ZIP it... ZIP it good... - How ZIPS projects the 2010 Diamondbacks
As Zephon mentioned yesterday, Dan Szymborski's ZIPS system has come out with its 2010 numbers for Arizona. It's the last of the "big four" public projection systems [Bill James, CHONE, Marcel, ZIPS] to go to press, so that means I can begin work on the Communiry Projections. Those will be starting after I finish the 2010 preview by position series, so likely about when pitchers and catchers report. For the moment, however, let's just extract the basic numbers and see what ZIPS has to say about our everyday players next year
The good news on first eyeball is, ZIPS projects six everyday players to have an OPS+ of 100 or better in 2010. This would be a marked improvement on last season, when we had 3 1/2 there - Mark Reynolds, Justin Upton, Miguel Montero, with the half being Ryan Roberts. The first three are projected to repeat, though the numbers for the trio all show a slight regression, of between three and ten OPS+ points. This is something njjohn mentioned with particular regard to Upton, in the RF preview piece: all the projections for him see Upton slipping. I think it's because - and this goes for Montero and Reynolds too - 2009 was his first "good" season, and the ones prior to that still carry enough weight to drag down the numbers, countering the expected aging improvement.
Joining them in the 100+ club, ZIPS says will be our two new arrivals, Adam LaRoche and Kelly Johnson. The former is projected to bounce back almost exactly to the 2008 level, with ZIPS believing last year to have been an aberration. After two consecutive years of 122 OPS+ for LaRoche, Dan hardly sticks his neck out when he predicts a figure for Adam in 2010 of...122. Particularly encouraging, ZIPS also expects Conor Jackson to make a strong recovery from valley fever, and return to the kind of numbers produced from 2006-08. This joins the other systems, which have similar OPS expectations to the .798 from ZIPS [in the range .783 for CHONE to .806 for Bill James].
No great surprise that the two players not projected to reach 100, are Stephen Drew and Chris Young, though there is some scope for optimism with both. Drew's projected OPS+ of 93 is a mild uptick from 2009's figure of 89, and Chris Young's 90 would be ten points better than the 80 he delivered last year [and give Zephon a good chance of winning his bet]. What we are seeing here, on both ends, appears basically to be ZIPS projecting regression towards league average: good players will tend to get a bit worse, while bad ones will improve. Anyway, here's a chart for the eight anticipated "everyday" players, along with their 2009 OPS+, and also the OPS we got out of the position as a whole last year.
| 2009 Actual Results | 2010 ZIPS Projections | |||
| Player OPS+ | Pos Prod | Player OPS+ | Player Prod | |
| 1B Adam LaRoche | 122 | .228/.321/.396 | 122 | .287/.363/.520 |
| 2B Kelly Johnson | 83 | .298/.372/.448 | 108 | .279/.352/.472 |
| SS Stephen Drew | 89 | .265/.330/.417 | 93 | .265/.324/.444 |
| 3B Mark Reynolds | 123 | .247/.336/.487 | 113 | .258/.341/.509 |
| LF Conor Jackson | 33 | .265/.317/.402 | 103 | .278/.357/.441 |
| CF Chris Young | 80 | .219/.293/.379 | 90 | .236/.315/.440 |
| RF Justin Upton | 126 | .294/.358/.498 | 122 | .282/.363/.521 |
| C Miguel Montero | 110 | .266/.345/.437 | 100 | .275/.342/.451 |
Caution needs to be exercised comparing 2009 Position Production and 2010 Player Production, because the latter does not take into account production in games when our "everyday" player is replaced by someone off the bench - whether due to injury, rest, etc. Such outings would mean that the overall production from, say, 1B is likely to be less than 162 games of LaRoche. That said, the numbers suggest big improvements are projected in 1B, CF and LF, with marginal upticks at SS, 3B and RF, while 2B and C should be there or thereabouts with their 2009 numbers. Again, this is based on the players in question performing to expectations and getting the great majority of starts.
Speaking of the bench, it's a bit up and down. Ryan Roberts and Chris Snyder both project at an OPS+ of 95, which isn't too bad. However, Gerardo Parra is only at 88, hardly a breakout season over this year's 85 - Dan also gives Parra an 80% chance of being in the bottom twenty percent of left-fielders. ZIPS is also fairly bullish on Jeff Bailey, though not quite to the same extreme as CHONE, and Augie Ojeda's value will continue to be almost entirely from his glovework.
In the pitchers, the one that stands out is Dan Haren For Cy Young. 17-7 and a 3.04 ERA, with an ERA+ of 155? For comparison, Timmeh the Toker is projected for an ERA+ of 162 when not hitting the bong; with just three teams left to do, Lincecum is the only pitcher to date better than Haren. I'll happily have another cup of that particular Sedona Red Kool-Aid. ZIPS is also fairly optimistic about Brandon Webb's return, though last season has, obviously, led to a drop in his projected starts to 26. It is also worth noting that Webb, over 2007-08, outperformed the estimates of seven of the eight projections, performing an average of one-third of a run better over the two seasons.
Edwin Jackson gets an ERA+ of 117, giving us a solid 1-2-3 at the top of the order. [Though ZIPS like Max Scherzer even better in Detroit, albeit over fewer innings - 3.70 ERA in 112 IP] After that, there's a bit of a drop-off, no-one else being projected as a starter has an ERA+ better than 95 - though that is probably close to league-average for a starter [relievers generally have a higher ERA+ as a group]. Curiously, ZIPS says Rodrigo Lopez would be the best pick as #5, with an ERA+ of 94, but there is basically little or no difference between him and Bryan Augenstein (93) or Billy Buckner (92). [Correction: There's a minor typo in the BTF piece: Augensterin's ERA+ is actually 96, but there's still not a clear difference between the trio] The table below lists the six pitchers who made five or more starts for Arizona last year, and the top six, by ERA+, as projected by ZIPS.
| 2009 Actual | 2010 ZIPS | ||||||
| Name | Starts | W-L | ERA | Name | Starts | W-L | ERA |
| 1. Dan Haren | 33 | 14-10 | 3.14 | 1. Dan Haren | 34 | 17-7 | 3.04 |
| 2. Doug Davis | 34 | 9-14 | 4.12 | 2. Brandon Webb | 26 | 12-7 | 3.50 |
| 3. Max Scherzer | 30 | 9-11 | 4.12 | 3. Edwin Jackson | 34 | 13-10 | 4.07 |
| 4. Jon Garland | 27 | 8-11 | 4.21 | 4. Ian Kennedy | 16 | 3-5 | 5.00 |
| 5. Yusmeiro Petit | 17 | 3-9 | 5.72 | 5. Rodrigo Lopez | 21 | 6-9 | 5.00 |
| 6. Billy Buckner | 13 | 4-6 | 5.89 | 6. Bryan Augenstein | 21 | 6-8 | 4.97 |
Just for amusement, let's sum the numbers for those six starters - ZIPS is somewhat uninterested in playing time estimates (as Dan said in a comment here yesterday, "Figuring out who’s going to actually play isn’t really a job for a projection model"), but it has the 2010 top six down for 152 starts, very close to the 154 by the top six in 2009.
2009: 154 starts, 927.1 IP, 4.16 ERA, 47-61 record
2010: 152 starts, 911.2 IP, 4.03 ERA, 57-46 record
A combination of better starting - especially out of the #2 spot and at the bottom of the rotation - and more runs being scored in support, clearly helps. If Buckner (or whoever mops up the remaining ten starts) and the bullpen can go .500, that's give us 86-87 wins. As another yardstick, five teams got a better W-L record than +11 out of their starters in the NL last year. Four of them made the playoffs (the exception, Atlanta's 65-49 rotation). So, if not quite there, it' certainly would be a step in the right direction for the Diamondbacks.
Finally, there's the relievers. At first, I was stunned to see us with no less than eight relievers posting an ERA+ of over 100. What a turnaround from 2009. Er...not really. Of the eight relievers to throw 25+ innings for Arizona in 2009, seven ended the season with an ERA+ of better than a hundred, and the eighth was Leo Rosales, at 96. Yes: I know it didn't seem like that at the time, but particularly in the second-half of the season, our bullpen was actually not bad at all. However, I'll get more into that when I reach them in our 'preview by position'. For now, however, just don't get over-excited by the ZIPS projections.
My enthusiasm is dampened even further by the realization that one of the over-100 crowd listed is Bobby Korecky, who seems to have dropped off the face of the Earth since the end of the season, and was presumably listed for us, in the absence of anywhere better to put him. Meanwhile, not listed is Zach Kroenke, our Rule 5 LOOGY, who has to be kept on the roster, yet whose ERA+ is projected to be slightly worse than...Tom Gordon. On the other hand, ZIPS likes Aaron Heilman and Bob Howry a good deal more than CHONE, which valued them as a collective "Meh." Howry, in particular, does a lot better: ERA here, 4.09, compared to CHONE's 4.72.
As with all projection systems, ZIPS isn't perfect and these numbers should just be taken as another piece in the puzzle. Bear that in mind when discussing these. But as Szymborski says in his introduction, "There's enough of a core here, with some things going right, to be a player in the wild card race." Here's to that.

someone needs to chop some snakepit faces on the devo pic above. tia.

Not many people know this
But Jim was actually one of the members of Devo. I won’t point him out, but it’s pretty obvious when you look at the picture.

Ian Kennedy
If ZIPS is anywhere near correct, and all we get out of Ian Kennedy is 3-5 with an ERA of 5.00, the Sherzer trade will be a completey bust for the snakes, IMO.
The way I'm looking at that trade is
Scherzer into Jackson
Schlereth into Kennedy
I’ve not got ZIPS for Schlereth, but to compare apples to apples, CHONE has him at 4.64 and only 33 innings, with Kennedy at 4.40 and 94 IP. Rather better for us, especially given Detroit is a more pitcher-friendly park than Phoenix.

But
We gave up years of control on Sherzer for Jackson/Kennedy, and are spending more money this year also. We also gave up possible upside on Sherzer that probably doesn’t exist for Jackson/Kennedy. In my mind, this trade only makes sense for Arizona if we get a decent #4 starter (lots better than 3-5 with a 5.00 ERA), OR if Sherzer gets injured (therefore we could rationalize trading him becasue of delivery concerns). If all we get is a “push” between Sherzer/Jackson, and a mild improvement over Schlereth and not a viable #4 starter, I think the trade sucks.

We may lose upside
But we also lose a ton of downside. Look at what Seattle got for Morrow.

I don’t think it’s fair to say that the upside on Scherzer that doesn’t exist for Kennedy. Quite the contrary, Jackson has proven himself a better starter at the same age. The big issue are the years of control on Scherzer vs. Jackson. That could wind up being huge, no doubt. The injuries are really the wildcard here.

Zips
My projections vs Zips would say…
OPS / Player
.824 / K.Johnson (Big Under)
.793 / M.Montero (Over)
.798 / C.Jackson (Under)
.765 / R.Roberts (Under)
.768 / S.Drew (Even)
.850 / M.Reynolds (Slight Over)
.741 / G.Parra (Slight Over)
.755 / C.Young (Slight Under)
.884 / J.Upton (Even)
.744 / Allen (Over)
.703 / A.Ojeda (Under)
.753 / T.Abreu (Under)
.883 / A.LaRoche (Big Under)
Xei, do your predictions tend to run lower than ZIPS, or do you just not like the DBacks this year? I’d be interested to have your projections for LAD compared with ZIPS.

Similar chart
as with the DBacks, but for the Dodgers this time. My projections vs Zips. Over = I think he will do better than Zips, Under = I think he will do worse than Zips.
Dodgers
OPS / Player
M.Ramirez / .943 (Under)
A.Ethier / .871(Even)
M.Kemp / .855 (Under)
J.Loney / .800 (Under)
C.Blake / .798 (Slightly Over)
R.Martin / .759 (Way Under)
R.Furcal / .725 (Even)
B.Dewitt / .726 (Even)
J.Carroll / .666 (Even)
J.Repko / .661(Under)
According to my own projections, Zips way over-inflates the Dodgers hitting stats.
vr, Xei
Yes...
Zips imo is way to overly optimistic for Dodgers hitting stats. That being said, I still think the Dodgers will win the NL West again this year. But of course 3 or 4 teams all have a realistic shot at winning it.
vr, Xei
Do you think ZIPs is too optimistic in general or is it a fluke that they were too optimistic with the DBacks/Dodgers?

To be honest with you
I haven’t studied Zips close enough to make that call. But here are the three main critieria I would use to judge how good a projection system is.
1. Accuracy of rate stats. (ie – HR%, 2B%, 3B%, SO% BB%).
2. 50/50 (or close to) split on over/under of plate appearances (hitters) and innings pitched (pitchers) compared to actual empirical results.
3. Counting stats of total projected population should be close to or just slightly below actual empirical results of counting stats.
I will let others come up with the correct yardstick to measure these three things and come up with the proper weighting, but I believe a good system should do all three things well.
