The Dangerfield D-backs: We Don't Get No Respect

One of my SB Nation colleagues, Jay from Let's Go, Tribe got a nice job helping cover the post-season baseball for Esquire. However, in a preview, he wrote the following about the Cubs-Diamondbacks match-up:

While acknowledging a genuinely exciting Game One matchup, it's hard to work up much enthusiasm for this series. Its biggest mysteries are (a) how a club as unimpressive as the Diamondbacks ends up with the top seed, and (b) why the pathetic NL Central can't manage to produce a better playoff team than these Cubs... I am literally getting drowsy just typing this. It's a shame only one of these teams can lose this series, because we deserve better than either one of them.

Naturally, I was not happy with this view, and expressed my objections to Jay, pointing out things like the 49-1 differential in four blow-outs. He back-pedalled initially, and in fact, showed a degree of flip-floppery more appropriate to a Presidential candidate, by saying we were "a young, interesting and fast-improving team" - a sharp contrast to calling us "unimpressive" in his original entry. But he has gone back on the attack in his latest piece:

It would be nice if only Very Good Teams got the opportunity to win the World Series, and I'm skeptical that a team that can't win more than 85 games or outscore its opponents is a Very Good Team, let alone a Great Team. It offends me a little that they get to take their shot, and I feel that way not because I understand the math -- again, please don't throw things -- but because I simply want to see the best teams compete for the championship. Seriously, eight out of 16 teams in the NL outscored their opponents, is it really so much to ask that the D'backs be one of them?...

Well, the blowouts may distort the numbers, they're not good, and even if we throw out some "meaningless" runs, you still end up with a team that only scored one run on those four days while their pitchers got hammered. And the D'backs' bullpen patterns aren't all that different from all the other teams. The Diamondbacks got enormously lucky this season, to a degree that nearly always portends a huge step back in the next year.

Ah, yes: the old "the Diamondbacks were just lucky" argument. First, this demonstrates a basic misunderstanding, very common among statheads, about the game of baseball. It's not about having the highest team batting average. It's not about posting the best run-differential. The game is decided simply by scoring more runs than your opponent on the day. That is the only measure of "best" which actually means anything, because playoff spots are not awarded on the basis of Pythagorean Projections.

Certainly, you can look at other factors, to analyze where and how a team is performing,. But claiming the Diamondbacks are not a good team is like saying Bill Gates isn't rich because he drives a Lexus. You can look at someone's car, and it might give you a good idea of how rich they are - though why bother, when you can just look at their bank-account? Ditto baseball: while secondary stats are nice, using them to judge how "good" a team is folly.

Item #1. If the Diamondbacks were a 79-win team, as Pythagoras believes, this binomial calculator gives them only a 4.9% chance of reaching 90 wins. Item #2. Baseball Prospectus predicted a 7.0% chance of us sweeping the Cubs. Combining these two, the odds of both happening is one in 289. Really, there's a point at which blaming "luck" in the face of relentless evidence goes beyond stubborness, and begins to drift into idiocy. A good scientist, when the evidence piles up against them, will admit that their theory is flawed, and will begin to look around for a better theory. Jay, however, seems to feel that when the facts disagree with his theory, the facts must be disposed of. Blaming "luck" for an 11-game differential - especially two seasons after the same manager, for the same franchise, posted exactly the same improvement - is like continuing to play poker after your opponent gets three royal flushes in a row. There's a certain point beyond which it's time to check the deck.

Meanwhile, the Arizona Diamondbacks laugh, move along, and keep right on winning. To quote the great philosopher Eric Byrnes, "Sometimes every now and then there are teams out there that defy the numbers. We seem to be one of those teams. This is one of those things you can't really explain other than the fact that there are 25 guys in here who know how to win baseball games." Rather than whining about this, and saying the playoffs "deserve better", I would think any neutral fan would celebrate the team's slaughtering of the Run Differential sacred cow. Because sometimes, a reminder that we really don't know everything, is a refreshing thing.

Hear, hear
Upon reading this entry, I decided to register and post this comment. I am a Cardinals fan, but more importantly, a BASEBALL fan. I have been keeping track of all the blog entries for the teams in  contention this year.

And this is the best entry I have read so far. Simply put, while baseball is a game of numbers, it is not JUST a game of numbers. It is a game of numbers on any given day. The DBacks are an exciting, young team, who find ways to win(Anyone who sweeps the Cubs is tops in my books). And that is what baseball is. Who can win on a given day. (And I understand this methodology, I am a fan of the 2006 World Champions who are only that because they got hot at all the right times last year).

I am a stathead, so I know all of statistics that say the DBacks are a subpar contender. But I am also a student of the game, and a college baseball player. Stats are important and often time, CAN tell the story of a team. But when a team finds success despite these stats, that's true baseball: Finding a way to win. Through small ball, hustle, or timely run support. Just win. Which the DBacks do.

So I guess I'm saying: great post. And let's go DBacks! ... at least for the rest of this season.

You're very welcome here!
And thanks for the kind wishes. Stick around for the NLCS, and WS. (Should we make it!)

Nothing would make us more pleased than sticking it to all the "sage prognosticators" who want to talk down to the NL, and especially the Dbacks and Rockies. (How 'bout them ESPN writers, eight of whom out of ten picked the Cubs to win the NLDS!!)

Come on, Sandy Baby, loosen up. You're too tight.

Clearly, we were JUST lucky. For 90 games.
Same thing during the NLDS. Someone forgot to give those mighty Cubs the memo that we're just lucky and have no baseball ability. I guess it just goes to show that you can buy players for $300 million, but you can't buy a team.

Regarding the Esquire article, we were discussing the same thing at Purple Row. I think I'll just copy and paste my post from over there:

Well, the headline is 'Sox Win! Phillies Lose.'

I think that's all you need to read to know that it's going to be east coast centric. The next blog post is, 'Cubs lose a close one'. He mentions the outcomes in terms of the Phillies, Red Sox and Cubs; as if the Rockies, Angels and Dbacks had nothing to do with any of it.

Idiotic media. And now they get to pay, by having to watch an all-unknown NLCS.

DbacksSkins... I hail from here and here.

Let's go, Dbacks. Heck, now that the Rockies are the other NLCS team, we're still getting no respect.

We won the NL West for a reason, dipshits.

Another item that nobody wants to talk about...
...is the fact that we went 15-9 in September in meaningful games (not including those final 2 Colorado games when we used a split squad of Sidewinders and BayBears) and outscored the opposition for the month. The negative run differential is mostly due to earlier in the year, before our pitching was set, and as Jim pointed out, a few select blowouts.

Unbelievable
I thought (and still think) the Rockies got a lot of disrespect. But that's mostly in the form of (like in the Esquire blog) ignoring the team entirely.

Whining that a team shouldn't be in the playoffs, doesn't deserve to be in the playoffs, whatever, is a whole new level of stupidity. Like it or not, the DBacks, and hey, guess what, the Rockies won 90 games in a division where the third place team won 89 games and the fourth place team was over .500.

Everyone's said what's on my mind, which is, look, the team had a weird statistical year, but still won 90 games in the toughest division in baseball! That qualifies them as being a good team.

Compare that to the Indians, who won 96 but in a division where their opponents won 24 fewer games than opponents in the NL West, or the Sox, who won 96 where opponents won 20 fewer games, and you'll see that the DBacks and Rockies are very good baseball teams and do deserve to be there, maybe more so than teams in the ALCS. Because I'll tell you this: playing in the NL Central and maybe the East as well, is it a stretch to say that any one of these teams would have won 100 games?

Friendly Rox Fan. Is it just me, or does Eric Byrnes play baseball high?

now we're having some fun
Howdy everyone.  I'm the villain.

I hope to come back later and really go into more detail with this -- on Esquire.com, there is less opportunity to really go in-depth and get the nuance of some issues, both because of length and audience.  There is a very interesting debate in this -- though I hope you can drop the stupid "flip-flop" references.  I have not flip-flopped, and it's a cheap debating trick, beneath both of us.

For now, I just want to clear up a few misconceptions.

  1. Scott and I are both from the Cleveland area.  You may enjoy dismissing criticisms as East Coast bias, but it doesn't make any sense in our case.
  2. Scott and I are not the same person.  He's saying some stuff, and I'm saying other stuff.  It's clearly marked -- another sign that we have some "critics" who don't actually read what we wrote.  I won't defend everything he wrote, but I would defend some of it.
  3. I picked the Rockies, even though I now live in Philadelphia and somewhat root for the Phillies.  (How's that for bias?)
  4. Scott also picked the Rockies -- again, did the critics even read any of what we wrote?
  5. I never said the D'backs were boring, even though the excerpt above makes it look like I did.  That part about feeling drowsy was not about the D'backs, it was about the constant, same-old national TV coverage of the Cubs that I expected to see.  (Again, go read the article, you'll see.)
  6. Just for the record, I started talking favorably about the D'backs in my very next post.  I made a point of not making a pick, but I would have picked them.  It was, in fact, the first substantive thing I said about either team.
I like the Diamondbacks lineup. It's fun to watch a young, talented team, because there's an X-factor in not knowing if they're developing right there in front of you. (That also makes them harder to scout.) Young, Drew and Reynolds could all be great players, even if they're not yet, and they all showed signs of maturing as hitters over the course of the season. Granted, you kind of have to squint to see it in Drew's case, but it's there.

Maybe some other "mainstream writer" also made those observations, but I never saw them anywhere.

7. I hate big-payroll rent-a-player teams -- probably a lot more than you.  Geez, I'm an Indians fan, we're playing the Yankees, do you really have to ask whether I'd root for the D'backs or Cubs?  Think about it.

My final comment for the moment is that I know we have the best possible NLCS matchup ahead of us now, and as a fan, that pleases me a great deal.

Appreciate you stopping by
Now, if only we could get Nate Silver here for a merciless beating with blunt objects, er, I mean "discussion". :-) Perhaps "flip-floppery" was harsh, but your position certainly seems to have undergone some rapid revision, shall we say: the 'unimpressive' D-backs of your preview are, three games later, 'interesting and fast-improving'?

Anyway, look forward to hear a full response in due course, though I appreciate you probably have more important things to do right at the moment. :-)

by Jim McLennan on Oct 8, 2007 9:59 PM EDT to parent up reply reply actions actions   0 recs

actually
The answer to this particular charge is very simple.

Based on their full-season numbers, the team is unimpressive.  Looking more closely at the in-season development of individual players, it starts to get interesting.

I don't even see the two descriptions as contradictory.  I didn't originally say they were boring, just unimpressive.  And I didn't later say they were impressive, just fast-improving.

Of course they will be showcasing the ALCS between Boston and Cleveland or New York (network people probably hoping and praying it's NY) in primetime, so that's why we get the early afternoon start time.

Tell me about it
There is a reason I didn't go to any of the NLDS games: because I knew I wouldn't be able to afford them AND the NLCS. If we get to the World Series, we will be going - we promised ourselves that after missing out in 2001 - but, damn...still, our kids can pay for their own damn college education. ;-)

This just in
The Diamondbacks were the best team in the National League this year.  I have to restate this every once in a while because it seems that nobody outside of this board and our local paper remembers/recognizes this.  

I'm still cheering for a Cleveland/Arizona world series and I hope the national media enjoys every second having to cover these two medium market teams with no brand names.  It is, after all, what baseball deserves after all of this cable/satellite bullshit.

Here's to a Royals/Diamondbacks world series next year.

Luck v. Intelligent Design?
while secondary stats are nice, using them to judge how "good" a team is folly.

It depends what question you're asking, what you're  assessing; what level of measurable, reproducible "good" you're talking about. Jim, you often say the only thing that matters is the final W/L. And, at the most basic, important, recognizable, "fan" level, you're absolutely right. The team with the most wins, by definition, is "the best."

But, the issue of whether this W/L record results primarily from intelligent design or  happenstance is a different question, one with a less  self-evident answer.

On the one hand, this team exhibits many qualities that may enable it to "beat" Pythagoras somewhat.  They cant create alot of runs, but they can steal a base and manufacture the one run that wins a game. And they shut off oppenents' running game well. Obviously the pen is great, which provides pythagorean leverage. Maybe Josh stockpiling innings eating starters has something to do with it - I'm open to all that. But the problem at the end of the day is this: Even if one gives Josh and Bob Melvin all the credit in the world for the above construction and resource utilization, no GM that I know of goes into preseason saying, "Our plan is to get outscored by our opponents yet by shoring up the bullpen, improving the running game, etc, we'll manage our negative differential so well that we'll make a run at the pennant, have the league's best record, etc.

Nobody does that. As far as I know, nobody does that because it doesnt make any sense. It may "happen", but as a "plan", it doesnt work.  

There's a great deal of historical evidence that luck has played some role here, and reasserting this year's W/L record doesnt disprove that, so much as change the "question" - back to the one with the self evident answer.

P.S. Enjoy the playoffs :-)

If Jim wrote that the sky was blue, would you argue which shade? :)

Item 1 etc.
90% of printed statistics are lies and all, but if you're going to try to use them against the sabermetricians, you might want to get them straight - multiplying the probabilities of events together to get an overall probability only works in the case of independent events, and those two events you cited there are not independent. So the "1 in 289" claim is a bit dubious - the point you made is taken, but since you are basing some kind of argument about the scientific process on that stat, you should account for the fact that you're compiling the stats after the fact. The way you've stated them is akin to flipping a coin, having it come up heads ten times in a row, then flipping it an 11th time, getting a ehads and saying "there was only a 1 in 2 to the 11th chance that that last coin would come up heads!" Nope, it was 50-50. So the DBacks sweep of the series, if any accuracy can be attributed to BP, was just a 7% occurrence, not the 1 in 289 that you claim. And 7%, last I checked, is far bigger than the standard science p-value delimiters of .01 or .05, so I think your "rethinking the flawed theory" metaphor is less than accurate.

Also keep in mind that sabertmetric stats are "designed" largely to be predictive and not descriptive. The pythagorean win/loss stat is based off of years of evidence, and it does not purport to accurately reflect the records of every team in recorded baseball history - it's a correlation. So there's a heavy correlation between outscoring your opponent in toto for the season and having a good win loss record, but there's no claim that the opposite is impossible. In fact, it clearly is possible, and even sabermetricians would point to the DBacks as evidence of that very fact. I would say that the only thing that season end totals would indicate is this: if you only score 80 runs in a season, it is impossible to finish with 90 wins :)

That said, the DBacks did win 90 while being outscored, which apparently is something that occurs 5% of the time. And the DBacks fulfilled that 5%. Sweet. As a commentor mentioned, this is certainly possible if not desirable - I don't think anyone would go into the season planning to operate that way.

Probably the thing that has everyone so irked is the use of the word "lucky." On the one hand, I would say get over it - there's a lot of luck in baseball, and everyone knows it. But a more apt expression here is probably "good timing." Now, how much of the DBack's good timing is due to good fortune of lumped together hits and such versus how much is due to good managing and key performances is debatable. Regardless, you're only getting "no respect" from people who don't know any better - the sabermetric stats seek out trends and tendencies, not absolutes, and just because the DBacks record and performance has come up in the unlikely column does not devalue it - if anything it betters it, they are coming through DESPITE overwhelming odds to the contrary.

SO, in short, screw the negative vibes and bad application of statistics, but don't fall victim to delusional meta-narratives about the "awesome chemistry" of the Diamondbacks - they have been the benefactors of some incredibly well-timed play regardless of its sources in luck or some ability to step up when it matters, and it's okay to root for an "overachieving team" while still maintaining a level-headed stance that hey, Chris Young's .295 OBP probably could use some improvement.

Whining
First, Young, his second half OBP was .314!

I think we're more irked by the fact that while we did win 90 games, we're looked at as a team that's at the same ability of the Pirates and Giants.  A win is a win and I'm not sure I care too much about how you get there, when it's said and done.  Maybe we're all kinda mad that the Cubs, Yankees, Red Sox, and Dodgers are the best teams every year?  Not gonna happen, especially in the NL.

The fact is that we weren't the only team to defeat Pythagoras this year.  The Mariners had nearly the same run differential and finished with a nearly similar 88-74 record.  They didn't make the playoffs because they play in a league and division that's more top-heavy.

The Rockies outscored opponents by 102 runs, yet finished a half game back in their division.

10 teams finished better then the pythag record.  16 finished under.  (Red Sox -7, Yankees -5)

Instead of all of the sabermetricians, mathematicians, or "experts" hining about how terrible the Diamondbacks are, why not go and make yourselves useful and figure out why the league was so off this year.

Maybe because Pythagoras doesn't work when the league has parity?

by nihil67 on Oct 8, 2007 7:29 PM EDT to parent up reply reply actions actions   0 recs

Whining?
Okay, your leadoff hitter is still 20 points below league average, and he was even worse in the first half of the season! .314 is terrible! Why are you pointing that out?!??!?!!

Perhaps a course in bell curves and normal distributions is in order. My comment is not whining, and in fact is saying that people should stop whining altogether; statistics apply to norms and large data sets, not individual applications. Use of the phrase "defeating pythagoras" demonstrates a fundamental misunderstanding of what that stat attempts to divulge. If you flip a coin heads twice in a row, did you "defeat probability?"

To make it clear - props to the DBacks! They're having a great season. Their stats are fairly mediocre. It's cool, and it's a relative outlier, but it does not disprove anything sabermetricians are saying. besides, if the predictive stats were perfect, this would make for some fairly boring television.

But everyone else is.

"Okay, your leadoff hitter is still 20 points below league average, and he was even worse in the first half of the season! .314 is terrible! Why are you pointing that out?!??!?!!"

Because I knew it'd piss you off.  I don't want him to be our lead-off hitter, if it makes you feel better.  We won a lot of games with him up there though, didn't we?  That's got to hurt right in the math.

"If you flip a coin heads twice in a row, did you 'defeat probability?'"

Uhm, Yes.  Haven't you ever heard the term "beating the odds."  This is what they're talking about.  I'm secure, if probability beats me, I'll admit it.  Probability has a pretty weak pitching staff though, I think I could take him in a short series.

'If you flip a coin heads twice in a row, did you
"defeat probability?"'

Well, since probability says there should have been 2 tails in there, and heads is the desired outcome, then yes, you've defeated probability.

To Errrrrrr is human.
Actually, you shouldn't "expect" one tail, since it happens only 50% of the time. You should expect an average of one tail over several trials, but on one, you shouldn't really expect anything other than something within the realms of possibility - if you got three heads on two coin flips, that would be strange.

The point is that the stats are used to describe the entire wealth of experience, so a singular instance should not evoke such violent considerations. We're just seeing the once in a while - if there's a roughly 5% chance that this is going to happen, that means 1/20 times - true, it's rarer than other outcomes, but it's still an outcome that's going to happen occasionally.

Outlier
You don't expect first and second-year guys to be consistently good - when they are, like Tulowitzki and Braun, they're ROY candidates.  Rather, you expect them to be brilliant sometimes and awful others.  (You cannot find a clearer example of this than Young's hitting line for the NLDS; 2 HRs, 1 single, 3 BB... and 8 Ks.)  

And when you have the youngest lineup in the majors, you expect enormous game-to-game variations.  A team like Arizona, which combines talent and youth to such an unusual degree, is precisely the kind of team that's most likely to give BP a case of the screaming heebie-jeebies fall well outside the usual statistical norms.

Pythagorean Winning Percentage
I'm not doubting that PWP (as I'm going to call it for this post, because I'm lazy) is right 98% of the time (or pretty damn close) but what I wonder is the actually proof of why it works.  Everything I've read basically sums it up like this: "Bill James was tinkering around and figured out how to apply the Pythagorean theorem to baseball teams."  No one seems to know why it works, or if they do it certainly didn't come up in my basic Google search.

So I guess my question is for you, sir, is what is the mathematical proof for the theorem?

Stay grindy, my friends.

That's the problem.
As far as I can tell, there's no causal link involved here. It seems as though they simply averaged the run differentials per win/loss record and called it gospel. One formula fits all.

It's a question of mistaking the symptoms for the disease.

Come on, Sandy Baby, loosen up. You're too tight.

Statistical stuff
Hmmm. The chance of the "79-win" D-backs getting 90 victories is 5%. The chances of them sweeping the Cubs was, independently, 7%. The odds of both happening is, it would seem to me, .05 x .07 = .0035, and that's where the 1-in-289 claim came from, not just the sweep of the Cubs. You can argue how truly "independent" these events are. But it seems undeniable that the D-backs are beating the odds with such relentless effectiveness, that it's time to examine the deck rather than airily dismissing it as "luck".

As you wisely point out, some lose track of the fact that there is a correlation between run differential and results, not a direct causation. The problem is some people now choose to regard run differential as more important than the actual number of wins, as a measure of a team's quality. Maybe someday they'll use run differential to decide playoff spots. But until then, the Pythagorean Standings are a second-order statistic, providing a mediocre estimate of a figure - wins and losses - which we already know exactly.

Certainly, I dislike the usage of the word "luck", simply because it's basically being used by most people as the antonym of the word "skill". I'm not strictly sure how much genuine "luck" - in the sense of random chance - plays a part in baseball. To me, poker is a game where luck plays an obvious part, but in baseball, it's less clear. I guess I'm with Thomas Jefferson: "I'm a great believer in luck and I find the harder I work, the more I have of it." [A version thereof is also attributed to Sam Goldwyn and Gary Player, but there's no evidence either of them could hit a curveball] But what I really object to is that run differential is a blunt object, which assumes every run is equal in value as a predictive tool. That's so ludicrously wrong, I'm not even going to go there: I will just remind you that Arizona used Jeff Cirillo and Augie Ojeda as pitchers this year.

Could the Diamondbacks improve? No doubt. Though you could frame the question the reverse way: why aren't the other teams performing better? But with Melvin having delivered two of the all-time biggest Pythagoras-busting seasons in his three years as manager, I wouldn't bet against our 2008 record being another 'over-achievement'. And that should put the fear of God into the rest of the National League - if we can win 90 games while being outscored, what the hell are we going to do when we start outscoring people?

I don't think
the poker analogy is apt. If a guy has picked up four royal flushes, he has certainly been lucky (or he's fixing the deck, and I hope you're not trying to say that the Dbacks are cheating).

I think part of the problem here is that people misunderstand probability theory. If a predictive tool (say, run differential) says you shoud have a certain outcome (79 wins) 45% of the time and another one (90 wins) 7 % of the time, that does not mean that the times you get 90 wins they are somehow not legitimat. If the meteorologist looks at the radar and says that there is a 7% chance of rain tomorrow, and when you wake up it's raining, you'll still take your umbrella outside with you.

Run differntial is not causal -- it does not say the number of games a team SHOULD win in a perfectly fair world, but the number of games that one should EXPECT a team to win a certain percentage of times. There is a lot of chaos in baseball, there are a lot of situational matchups, and I think that the low level war between people who talk about stats and people who talk about heart and clutch improperly drives us to extremes.

Luck in baseball
I would argue that the difference between slamming a line drive at the shortstop for an out and slamming it two feet over his outstretched glove is not something that batters can control with extreme accuracy - I will naturally concede that baseball players increase their chances of "being lucky" by being consistently skillful, but there are way too many plays where a margin of inches makes all the difference in the world. These guys are sweet, but I don't think they can control every aspect of the game; sometimes nasty hard hit balls turn into outs and sometimes weak grounders are hits, ergo some luck is involved.

The "luck" that sabermetricians speak of is not luck as in anti-skill, it's luck as in the fortunate clustering of the few hits and walks that you are getting. Again, no one's saying the DBacks are closing there eyes and getting blind-ass lucky; they are saying that the clumping of their hits and walks into the runs they are getting and at the appropriate times are more than you would expect given their numbers. And there have been a ton of saber-studies to show that claims at "clutchness" and the like are off base; it's easy enough to say that a guy WAS clutch in a previous year, but it is exceedingly difficult to predict who will be clutch in the following year - much harder than it would be to, say, predict that Augie Ojeda will not hit 50 HRs next year. That is also, incidentally, the same claim that is made by the pythag theorem, that given average clumpiness of runs scored and runs allowed, you would expect a given record.

So maybe a better claim is this - the DBacks are clumpy. And you can argue like crazy whether this is due to some skill of clumping that Melvin or the players bring (which is clearly part of the answer, given his penchant for properly using his bullpen and/or infielders in blowouts) or whether it's just the way the chips fell. One problem is that the ability of a team to play consistently clumpily - in other words, clumpiness as a repeatable skill - has not been shown to be  a probably supposition in baseball's history. There is a similar argument with bullpen strength and 1 run games - people tend to attribute a good 1 run game record to a great bullpen, but again, this is something that does not have a strong year to year correlation across the leagues in past seasons. The general feeling is that if you are a good team and consistently drumming your opponents, you won't be involved in as many one-run games. (In contrast, things like average, OBP, SLG, and such do have predictive correlations, so the assumption is that something controllable/skillful is happening there).

Regardless, I think it's the semantic use of clumpy = lazy that's irking the fans here. So I would suggest the more objective, less value-laden use of "clumpy" over lucky, and we can let the DBacks have their mystique over why they have been able to perform this way.

As for the probabilities, the problem is declaring things after their occurrence. See if this makes sense - what is the probability that the diamondbacks would have won and lost their games in the precise order that they did? (E.g. WWLWWWLWWLLLLWLWLWLWWWWW, etc.). The chances of that are probably one in a gerbillion, but I can't very well then say that "wow, the chances that the diamondbacks would have won their games in that exact order and then beaten the Cubs in three games are one in gerbillion times 7%. They're really beating the odds; something's happening here."

I'm not arguing that before the season it was improbable, I'm just saying that it's misleading to multiply together probabilities in a predictive fashion after one of the events has already occurred. You have to look for the collective set of outcomes that would have satisfied you in this after-the-fact state, which should really include all instances where the DBacks make the playoffs and then win the first round, since that is what we really care about anyways. And I can't calculate that, but it's invariably higher than 1/289.

Good stuff
Appreciate the input: it's good to have a real debate about this, rather than "the D-backs suck," "No, they don't." :-)

[ there have been a ton of saber-studies to show that claims at "clutchness" and the like are off base ]

I dunno, last I read from Bill James was that clutchness might exist, but was largely undetectable, because its effect got lost in the noise of random variation. It's easy for a batting average, say, to vary by 50 points from season to season, and that can conceal a lot of things. Again, however, we're back to the sabermetricians' tendency to claim "luck" for any result that doesn't fit in with their expectations. That offends my scientific leanings, because it seems the easy way out: luck is the "Magic Bullet" of baseball stats.

[ So maybe a better claim is this - the DBacks are clumpy. ]

You would expect that to show up somewhere in the stats too, but the D-backs were dead-last in the National League for BA, OBP and OPS with runners in scoring position. 2 outs, RISP, we were 9th. Late and close, 5th; within 1 run, 10th. Even BABIP, the quintessential "luck" statistic, had us 15th. [I note, 41 points below the league-leading Rockies: either they were extremely lucky, or there's something to that religion thing. :-)] Any clumpiness seems strangely limited. About the only point I can find is that we were 2nd in pinch-hit OPS - and again, that's like bullpen use, an area where the manager can use the "right" player in a high-leverage situation.

[ As for the probabilities, the problem is declaring things after their occurrence. ]

We can't very well look at the projections before the season, because there aren't any. If the hypothesis is, that the D-backs are a 79-win team, how do you prove that on Opening Day? In addition, since everyone's run differential is zero at the start of the season, Pythagoras isn't exactly of much use. But Arizona outperformed Pythagoras every month during the season, until September: and the topic was brought up very early on, so we're not engaging in post-facto hypothesizing here. How often or for how long does the same team have to outperform before you should look at the engine?

Luck
might be invoked with degree of plausibility if a team has one insane fifteen or twenty game hot streak that offsets endless weeks of mediocrity; but it should be a lot harder to ride the luck train after one realises that Arizona went .500 in its worst month and a respectable but hardly scorching .593 in its best.  The very high game-to-game variability shouldn't obscure the longer-term consistency.

by peachy rex on Oct 9, 2007 12:28 PM EDT to parent up reply reply actions actions   0 recs

Right on
You're right on the averages with RISP and such - I suppose the clumpiness I was referring to is more that they clump the runs they do score into the games in which it serves them best. Also, and again this is just to point out the argument, not to say "DBacks suck" - they don't - but Arizona was pretty close to last in OBP, BA and SLG overall, so it's not all that surprising that they are last when R are ISP, too.

Everything I've read about "being clutch" is that it is a non-reproducible skill, that there's little correlation from year to year for player's ability to hit int he clutch (outside of the fact that, say, Albret Pujols hits better in the clutch than Chris Young, but that's just because he hits better generally, not because he rises to the occasion). The noise certainly obscures it if you study the stats of an individual player, largely due to natural flux and the lack of samples, but when you look at all players, there is no tendency for one who is clutch in year A to be clutch the following year. When BJ et al talk about hidden clutch, I gather that they mean that if there is clutch, it is not an attribute like most other things we use to describe baseball players - most players can take the label "is a home run hitter" or "is not a homerun hitter" since that stat tends to follow correlated trends, but since clutch does not across the board, you cannot equally apply clutch/not-clutch labels to players. So maybe a privileged few perform clutchedly and an unprivileged few perform unclutchedly , but since it does not differ from the expected distribution that you would get from outright randomness, you can't attribute that to anything about the players themselves.

Where you are spot on is that "luck" is a laden term that gets thrown around by the sabermetric folks. Unfortunately, what is going on is subtle - it's that the outcomes are matching predictions that would be entirely based on luck and are not differing significantly from them, so they can't attribute it to something beyond the random distribution. That is just how stats work, for better or for worse - if you can't see a difference between your outcomes and predicted random distributions, you are unable to reject the null hyp and claim that anything is going on. SO calling it luck is equally fallacious because you don't know that it's luck, you just know that it's certainly not the same kind of demonstrable skill as e.g. homerun hitting. What they should say is "we can't pinpoint what's causing this because it looks the same as a random normal distribution" and just leave it at that.

There's a whole 'nother argument that sabermetrics itself is fundamentally flawed because it assumes static abilities of players on a day to day basis and static applications of strategy over the course of years, but that's neither here nor there. But you do see it somewhat in the DBacks case - someone above was commenting on what the "proof" for the pythag theorerm is, and again, it's a statistic that describes the distribution, not one that pretends to be able to pinpoint exactly what happens in a season. The proof for why it serves as a reasonable approximation is the commonsensical thought that runs scored / runs against stat determines a win in an individual game, so extrapolate it to the regular season and mess around with exponents until you get something that reasonably models the win-loss records of teams via your formula. It's not perfect - and BJ himself admits that it falls apart at the extremes - and it's especially going to not be perfect if you intentionally thwart it. And I would argue that Bob Melvin did thwart it on occasion, by throwing Augie et al out there in blowouts and using his worse relievers when he was far behind as well. Essentially, if you don't follow "average manager tendencies," it's not surprising that your RS-RA does not follow the average prediction. Still, the question is whether the manager and players account for all of that exception to the model, and this is outside the grasp of the stats - but it certainly seems that the DBacks did a good job of scoring runs and preventing runs in a fashion that led to more wins than expected. Again, probably partially due to good managing/playing, but also probably due to some  happenstance timing.

Which is not a bad thing! As I hopefully convinced you above, luck happens in baseball. Going 90-72 instead of 81-81 is a swing of 9 games. So if you want to say that 5 of those games were due to sweet managing and 4 were due to timeliness, then fine. But it boils down to trying to make objective assessments, and betting on the team that gets outscored on the season, given the available data, seems unwise. Does that mean the Dbacks won't win or that you shouldn't root for them? Hell no! But the "no respect" line is tired - people are trying to make accurate predictions based on data, and the data are what they are. It's dumb for them to get uppity and attribute your success to luck, but it's equally dumb to feel offended that people are saying your team doesn't look good on paper. They don't! So what? Appealing to intangibles as a predictor of your playoff success is illogical - if there intangible, then you can't see them to use as predictors.

Really all of this boils down to an inescapable human desire to apply logical narratives to things that are not beholden to follow them. It's best to just enjoy the series drama than to get all cranky over who's disrespecting whom. Besides, aren't we supposed to enjoy rooting for underdogs? Won't that "I told you so" moment feel that much sweeter when you prove them wrong? You know, if you do?

Suffice it to say, this isn't how things are done in Phoenix and Denver. The D-backs and Rockies have exceptional young talent, and they're going to be serious contenders for the foreseeable future."

Here's your answer
"Well, the blowouts may distort the numbers, they're not good, and even if we throw out some "meaningless" runs, you still end up with a team that only scored one run on those four days while their pitchers got hammered."

4 days?

I looked through the entire schedule and here's what we scored in games that we lost by 5 or more:

-7, scored 4
-5, scored 6
-5, scored 5
-6, scored 3
-6, scored 4
-6, scored 5
-6, scored 1
-7, scored 3
-6, scored 1
-8, scored 2
-6, scored 1
-7, scored 1
-13, scored 0
-8, scored 3

-9, scored 1
-14, scored 0
-11, scored 0
-5, scored 3
-9, scored 5
-9, scored 0
-8, scored 2
-6, scored 1
-10, scored 1

24 of our 72 losses were by 5 runs or more.  Our run differential was -184 runs in these 24 games.  Everyone should be more amazed that we made it back to only being down by 30.

Throw out the stats, look at this fact. The Diamondbacks play in the best division in baseball. From A(rizona) to Z(ito) the NL West is stacked with great pitching and tough hitting ballparks. The Cubs and Phillies were lucky that Bud Selig allowed them to participate in the playoffs. The Padres could have swept either team and the Dodgers probably would have taken them in five. The top pitchers in the National League when you look at ERA and Wins was Webb, Peavy, Penny, Zambrano, and Francis.

[ The top two teams in the National League are playing each other in the NLCS, how often does that really happen? ]

Welcome, Charlie. The last time the two teams with the best records in the NL faced each other in the NLCS seems to have been 1995, in a shortened season, when the Braves (90 wins) faced the Reds (85). The next-best team had only 78 wins. Of course, "most wins" doesn't necessarily mean "best", as we all know, but in this case, it's hard to argue the D-backs and Rockies are not truly the best - much though the Disciples of Differential would have you believe Atlanta should be here, rather than Arizona!

there's definitely a lack of love for the D'Backs.  The Rockies may not get much respect either, but people clearly favor them over the D'Backs.

Just check out the poll on the SI MLB front page which asks who do you WANT to see in the playoffs and a whopping 74% say they want some form of a Rockies WS.

I'm not sure why the Rockies are more beloved than the D'Backs, but I'd venture to guess Todd Helton is a big reason.

I really just think
That one of the earliest comments was the best.

It strikes me as ironic in a sport where the only result is a win or a loss that there can be so much debate as to the statistics involved....

To my knowledge the most common mantra in all of sport is 'we're taking each day as it comes' if a closer blows a save he thinks about 'the next game'

If such things are true, then why does it matter what happened yesterday,last week, two weeks ago or 161 games ago? If you win that day then guess what you're the best team on the field. The D-Backs were the best team on the field in 90 games that they played this season. Every other team in baseball had the same number of games to win 90 and in the National League nobody else did that.

For me at least that's all that matters however the heck you got to the postseason you made it and you DESERVE to be there.

Whether you're Wimbledon playing long ball football or Liverpool who play some skillfull classy football, any team can win on the day (for reference see 1988 F.A Cup Final) Yes 'on paper' the Diamondbacks shouldn't win 90 games. On paper alot of things should happen....

Just remember that a win is a win, theres no such thing as 'bonus points' or a 'quality win' perhaps these things can be added in the future? heck why not put a target into centre field that if you hit you get 3 bonus wins and you're player is alowed to run 6 bases then the other team loses 2 wins. But that's not the game of baseball and the league rules the Diamondbacks played in.

I think the issue is this: we feel like we're being set up to be labeled by the media the StL Cardinals 2.0 and that just isn't the case.  We won 90 games in the toughest division in the NL, we have arguably the best bullpen in baseball, and also, arguably, the second best starter in the NL.  Our lineup is certainly no AL lineup, but it may well be a top tier lineup in just a matter of a few years.

More on Stats
I don't have time, alas, to read all the comments here. But, kind of like the D-Bax themselves, the comments look interesting and intelligent. Mostly. Two points:

Point 1: statistics is about whole data sets. Not about individual data values. You can summarize a season with some statistics, but the game is played game by game. That's why emotion and morale are so important.

Point 2: the two best teams in the NL are really going to play in the NLCS. For Easterners, if they ever bothered to look, it should have been obvious from Day 1 of the 2007 season that the Rox and D-Bax were good teams. The Rockies, in fact, may be the best team. Ever. That doesn't mean they'll win, but the Rockies are really, really, really good (and if I say it three times, it's true). Yankee fans are fond of thinking, in the aftermath of what Cleveland did to them, that somehow the Grand and Glorious Yankees were jobbed. They were beaten by a clearly superior team, and the Rockies are, I suspect, going to show everyone that they, in their turn, are better than either the Sox or the Indians.

But for Diamondbacks fans, there's always hope. And that's the greatness of the 2007 Diamondbacks: they never gave up hope. They never stopped trying.

nice
This turned into a very interesting exchange, which is cool.  I'll throw in a few cents of my own, as promised.

First, nobody ever said the Pyth method is perfectly predictive or perfectly constructed.  It makes no attempt to account for the effects of an unusually well leveraged bullpen.  It makes no attempt to account for marginally "unimportant" runs in blowouts.  I don't even know if it really should attempt these things, I just know that it doesn't, and those things do matter.

And let's also not forget, there is some luck (sorry, "timing") involved in the raw runs scored/allowed numbers, too, and even in the raw plate appearance stats used for "equivalent runs" and the like, and of course in one-run games.

Second, there is a specific reason that we know that Pyth record is a real indicator of how "good" a team is, and that is its predictive power compared to win-loss record.  That is, if you want to predict your team's actual record next season, their Pyth record this season is a more accurate predictor than their actual record this season.  That is, the correlation is higher.

And by the same token, the research shows that no team exhibits an ability to "beat Pythagoras" on a consistent basis.  That is to say, there is no evidence that it is an actual skill, or an actual sum of attributes of a team.  I know that the D'backs have beat Pythagoras pretty good two years out of the last three, and as it happens, the Indians have gotten beat two of the last three.  Unsurprisingly, fans of both teams have scrambled to try to figure out why, to say, as one user above has, that it's time to get a new f'ing theory.  But nobody's found a "why" that holds up to any scrutiny.  It really might just be a fluke.

As a fun aside, a post above bragged about how many more wins the D'backs' divisional rivals had compared to the Indians' divisional rivals.  The reason the Indians' rivals don't have as many wins because the Indians crushed those rivals head-to-head.  That is, the Indians' rivals went 24 games under .500 against the Indians, while the D'backs rivals went exactly .500 against the D'backs.  I'm not even saying that's better or worse for one team or the other, because both teams had to get their wins somewhere, I just though it was kind of funny.

As another aside, the contention that the run differential was run up early in the year "before our pitching was set" is just false.  In April and May, they went 32-23 while outscoring opponents 239-224, which suggested they had gotten just a little lucky.  June and July were more jarring, 27-26 and 207-249.  I mean ... wow.

But August was the height of this, far beyond anything earlier in the season:  they went 16-12 while being outscored 127-141.  Over a full season, that's like going 93-69 while being outscored by 81 runs -- 735-816.  Three worst games: 5-34 = -29.  Three best games: 27-10 = +17.  Throw those six games out and you get a 13-9 record and a 95-97 score.  They were also 6-1 in one-run games that month.

Now we get to the lucky vs. timely thing.  I actually don't like the "lucky" tag, though I can't seem to stop using it.  When statheads throw this out, what they generally are referring to is a situation where we have not yet quantified any specific cause for the trend other than randomness.  That doesn't mean that there isn't a specific cause, it just means we haven't found one.  Realistically, at this point, it means it's probably luck, but it isn't definitely luck.

Bill James himself has written about this, and not without controversy.  He wrote, basically, that we can't prove clutch hitting exists, but that we also can't prove that it doesn't exist -- and we probably never will.  The data is just too noisy, there are too many other factors to isolate clutchness.  He was talking about individuals, but it might as well be said about teams, too.

And that's where I get off.  I can't tell you that the D'backs aren't heroic or clutch or timely, only that my understanding of the numbers historically is that they won't be able to keep it up.  That is, they can't keep beating Pythagoras forever, but as I wrote for Esquire, they're likely to keep winning by simply simply improving their raw production.

Because, you know, they're so young and talented.  And interesting.

I guess I'll ask you instead
I asked this above but still haven't gotten an answer.  Why does Pythagorean winning percentage work?  What is the mathematical proof?
Stay grindy, my friends.

There have been some interesting claims
And I think that it deserves a deep-dive study by someone.  Specifically, I'd love for someone to investigate how teams perform vs. previous year Pythag record.  I can't believe that it's any possible indicator of future performance.  Hell, I still don't believe that it's an indicator of past performance.  The current formula shouldn't even be called "Pythagorean" anymore, as they raise to the power of 1.83 instead of 2 now.

by nihil67 on Oct 10, 2007 9:49 AM EDT to parent up reply reply actions actions   0 recs

what's the proof
The proof is the higher correlation it gives from year to year as compared to the win-loss records. It was developed as an empirical stat, so asking for a mathematical proof is a bit out of bounds. For comparison, how do we know that gravity has an approximate acceleration of -9.8 m/s^2? It's because we tested it over and over and that's how the numbers came out; there's no way to mathematically "prove" it, it's just a model that successfully represents the data.

Obviously the baseball pythag theorem is not as set-in-stone as gravity, but it was developed in an empirical way as well. The empirical way boils down to people tinkering around with formulas and powers until they got something that models correctly - and, as mentioned above, since the outcome of individual games is dependent on rusn scored and runs against, some formula involving your ratio of runs scored for to against was a rational place to start.

Again, don't confuse a pythag theory, which correlates effectively with the entire mass of stats, over a deterministic theory that says if A then definitely B. The pythag stat models the entire league over time, not just individual occurrences in individual years, so one team outperforming it in one year does not call for a rethink of the entire system.

Again, if you can think of things in terms of normal distributions it helps - there is a general rule that if you have a disproportionate body mass to your height, you are likely to die earlier. One  very fat short person surviving to ninety does not disprove the general rule.

that's right
It's a curve-fitting algorithm -- it was designed to describe the relationship between runs and wins (and losses).  And it turns out that that relationship has significant predictive value.  And it also turns out that baseball is not so easy to predict anyway.

One thing I didn't touch on was its in-season predictive power.  That is, a team's second-half record is far better correlated to their first-half Pyth record than its first-half actual record.  And by the time you get down to September, you've got five month of runs data to use.

Of course, the D'backs totally blew that projection out of the water -- but not by staying "lucky" or "timely."  In September, their actual run performance jumped.  They outscored opponents 138-119, which is a Pyth record of 15-11.

Their actual record in September?  15-11.  Which is one more reason why I have suggested that while some "luck" or "timing" surely is involved in their seasons record, they may have "grown into" their record at the end of the year.

Nate Silver at BP
just wrote something to the same effect :

"Considering how young these players are, I think we need to ask ourselves whether the Diamondbacks were getting hot in September ... or whether they were simply regressing back toward their true levels of performance. It was the April through August performance that was the aberration, in some sense."

Of course, this is what Arizona fans have been saying for months.

how nice of him to come on board...
Yeah, I was just about to comment on his unfiltered post. I am happy to see that somebody at BP is finally willing to live up to their usual standard when it comes to seeking a variety of explanations for unusual data, such as our current success.

Hop on board the bandwagon, Nate. I know it's hard to find, and kind of empty, but you're more than welcome here!

our win differential is more important than your run differential...

Certainly bodes well
Especially with a young team like this, I'd far rather have players that showed improvement over the course of a season [well, generally...someone's improvement didn't last long past the $30m contract! :-)] rather than flying out of the gates, and barely hanging on.

Run Differential Redux
Frankly, I wish we could give old Pythagoras a decent burial.  As was pointed out above, the name no longer applies because the exponent has changed from 2 to 1.83.  More importantly, neither version explains why Runs Scored (RS) and Allowed (RA) need to be raised to a power to estimate wins and losses.  The truth is, they don't.  Here is a formula that works just as well (or just as badly, in the case of the D'backs) and is far more intuitive.

Win Pctg. = .500 + (RS-RA)/(RS+RA)

Note there are no exponents.  A team that scores 800 runs and allows the same is expected to win half its games.  For every additional 10 runs it scores (or prevents its opponents from scoring) the winning percentage goes up by .006. .006 x 162 games = 1 game.  This is the source of the rule-of-thumb that says 10 runs = 1 win.

Still wrong
I do that and I come up with 79 wins... but the Diamondbacks won 90.

Nice try though :)

by nihil67 on Oct 11, 2007 11:58 AM EDT to parent up reply reply actions actions   0 recs

The other key here
is the erroneous assumption that the DBacks over the course of the year were a static team - their "young players" may have been improving steadily, as seems to be the same with the September positive run diff and such, but there's the more pressing point that they plainly did not have all the same players throughout they year. Upton coming up, Quentin going down, Hudson getting hurt, etc. - there are a lot of changes over the course of a season. Identifying a group effort, especially an effort from a dynamic group, as though it were a single static entity is a common reductionist flaw and one which, because of the limitations of statistics, sabermetrics has to unfortunately include each time it makes a claim. For one example, in order to have some kind of coherency to an argument about "Chris Young" or "the DBacks" or "the NL West," you behave as though these are static entities with static skillsets, when the reality is probably more nuanced.

On the other hand, Mr. Nihilist - repeatedly pointing out that the DBacks won 90 games doesn't really accomplish anything, as it has already been pointed out that this was an acknowledged possibility within the statistical analysis done in previous years using the pythag or related formulas. And all anyone continues to say is that the Dbacks poor run differential indicates a historically probable regression in the upcoming years, not a definite one. We'll see what happens, but pretending that you would want your team to get outscored year to year is absurd. I would also ask how far this neglect of runs scored and runs allowed should extend - do we stop worrying about ERA's or HR in our evaluation of players, too?

(And sorry if I offended you earlier with my joke about removing all the DBacks losses; I was just illustrating that removing certain games in a biased fashion is naturally going to affect the run outcome, so any kind of claims to hey, look at all the 5 run games the DBacks lost, is explaining away the stats in a manner that is obvious - the only way you can finish 90-72 with more runs allowed than scored is if you won a disproportionate amount of close games and lost a disproportionate amount of wide games. In short, duh. Explaining that trend would be much more interesting that simply repeating its existence ad nauseum).

And as long as I'm commenting over-verbosely, Jim, the point I was making about the odds is that it's misleading to combine those stats after the fact because it makes the outcome seem more outlandish than it is. Isolating just the Cubs series, for example - if the DBacks and Cubs are perfectly evenly matched, and you think each game is a 50/50 shot, then the DBacks have a (1/2)^3 chance of sweeping the series, or a 12.5% chance. In saying that they had a 7% chance of sweeping the series, you are saying that the DBacks had something like a 42% chance of winning each game. That's a pretty big difference, but it's not like saying the Cubs had a 2-1 shot on each game. But let's say you though that based on the regular season, you thought it should have been a more even 50-50 shot of the DBacks winning each game. Then they sweep. The problem is, you got what you wanted - more respect for the DBacks - but you can still make the same argument, that the 5% for the run differential during the regular season times the 12.5% for the post-season means the odds for these things happening was 1/160, so "something's wrong here."

The real problem is that a 5 game series is subject to lot of happenstance. Even if you've got an insane favorite playing an underdog, something like team a with an 66.7% chance of winning v. team b with a 33.3% chance in a given game, the chance that team a sweeps is only 29.6%, and that they win the series around 3/4 of the time. So if a team is theoretically twice as good as their opponent, they still lose the series a quarter of the time.

In short, it's difficult to use evidence from a five game series (or in this case, a three game series - HA!) to prove that your input probabilities were wrong. More data is necessary, which is exactly what someone commented above - baseball is difficult to predict.

ok
"do we stop worrying about ERA's or HR in our evaluation of players, too?"

Can we?  Add batting average and pitcher wins to that list and I'm on board.  Anyway, I think you're posting in the wrong board with the first paragraph.  As far as I can tell, we're the ones trying to convince everyone else that our team is non-static and improved over the year.  Others just want to say how boring and unimpressive our team is without looking past their sabermetric security blanket.

"On the other hand, Mr. Nihilist - repeatedly pointing out that the DBacks won 90 games doesn't really accomplish anything, as it has already been pointed out that this was an acknowledged possibility within the statistical analysis done in previous years using the pythag or related formulas."

Actually, I think it's quite necessary to continue pointing out what we had the best team in the NL this year by the only statistic that matters.  How else can we combat claims that this team is unimpressive or terrible?  

Please link me to where someone predicted a 90 win season for the Diamondbacks this year based on statistical analysis of previous seasons.  With free agency, player progression, player regression, and random player movement (like having 2 starters called up from AA), I can't believe for a second that it exists.

"(And sorry if I offended you earlier with my joke about removing all the DBacks losses; I was just illustrating that removing certain games in a biased fashion is naturally going to affect the run outcome..."

No offense taken because you didn't read what I said.  I wasn't taking them away, I was highlighting them.  We got beaten so badly in quite a few games, it would have taken us putting up 20 runs in some games for us to even think about getting back to even.  I was trying to illustrate that with some of the deficits, us only finishing down by 20 runs should actually be looked at as an accomplishment.

at least it's an ethos
Actually, PECOTA predicted 88 wins for the D'backs this season.  Is that close enough?

I wouldn't toss out HR just yet.  ERA is problematic but quite doesn't deserve to be lumped in with batting average -- let alone "Wins," which I simply won't reference at all anymore.

(Side note, Gammons has been touting Sabathia's 5-1 "record" against Santana and Verlander as a reason he should win the Cy Young.  It's been hard to convince my fellow Indians fans that this argument is every bit as stupid as giving the Cy Young to the guy with the most wins overall -- the Win stat is just as stupid for splits as it is in the aggregate.)

Finally, I feel like you're going to give yourself a coronary if you can't start having a sense of humor about this -- and maybe you do, but it sure doesn't come across in your replies.  It is what it is, and 90 wins is not some big impressive total anyway -- lots of teams have won 103 games and gotten beat in the first round -- and five NL teams won between 88 and 90 games.  So even if we only look at wins, the D'backs' superiority is marginal at best.

When the mediocre Cards won it all last year, I wasn't mad about it, mostly because they're a great franchise that had great teams for several years in a row.  It just so happened that this one year, they had some bad breaks in the regular season, injuries and off-years, yet they had the good fortune to get into the playoffs anyway, and the good fortune to win the whole thing.  All that good luck didn't change the fact that they were at the end of a great run as a team.  This year's D'backs kind of have the same story in the opposite direction -- this year they may have needed luck, but there's no denying their talent.  The '97 Indians were kind of in-between the two.

Bottom line, rather than bury your head in the sand and argue everything to death, why not just enjoy a bunch of talented kids basically going around de-pantsing all the teams with overpaid veterans?  That's what I'd be doing.

"Didn't read it"
You highlighted them and then said everyone should be surprised that the DBacks made it back to down by 30/20. I'm stipulating that when you go hunting and take out all of the 5 run loss games, then of course those are going to have a huge negative differential, and of course the other games are going to bring the differential back to where it was. We shouldn't be surprised that the other games made up the difference - in other words, "highlighting" any team's 5+ run losses shouldn't engender some surprise that the remaining games make up the difference.

And you said something along the lines of

"Holy shit!

Really!?

You done yet?"

which, apparently I mistook for offense instead of the constructive conversation that it clearly is.
