SnakePit Appraisals: Oliver Perez

What with all the excitement today, forgot about the writeup for our premier left-hander. Here you go... [Note, for similar reasons, the fifth part of Twitch's series will be carried over to tomorrow. Your arms deserve a rest from waving those pitch-forks...]

Mark J. Rebilas-USA TODAY Sports
  • "Oliver Perez was really good for the Dbacks in 2014 " - ford.williams.10
  • "Solid numbers, can be put in to get a lefty out and stay in to face the righty, relatively inexpensive and dependable." - TucsonTim
  • "Maintained Tower’s reputation as strong on finding bullpen help." Fangdango
  • "Lefty Relief Pitcher, 2014 results ERA=2.91 (only Diamondback relief pitcher with lower ERA was Marshall), FIP=3.23, faced 256 batters with 76 strikeouts, 24 walks, and 50 hits." - Makakilo
  • "He's a great piece to have on a team that matters. Sorry that couldn’t be us.:


  • "33 years old. Only Diamondback relief pitcher older is Ziegler, who is also the only higher paid relief pitcher." - Makakilo
  • "He fared poorly with 0 days rest,  and when his pitch count exceeded 25. Both would limit his value to any team, even if his stats vs LHB improved." - xmet
  • "Just don’t let the other team hit against him more than once thru the line up. And, don’t pitch him back to back days." - ford.williams.10
  • "Probably used too much after Ziggler was injured and his performance suffered in September because of it" - TucsonTim

Towards 2015

  • "A good influence for the young Spanish speaking guys on the team. He brings Big League experience, knowledge of how to pitch through stressful hitters and does not air out dirty laundry from the Clubhouse. - ford.williams.10
  • "Perez improved in 2014, and may improve again in 2015." - Makakilo
  • "Probably a trade candidate." - Edwong81
  • "Got to agree with Shoe, trade bait for a contending team (Tigers, anyone?)" - TucsonTime

Comment of the Thread


Gave him a 4

A few too many inherited runners scored…….but overall he did a good job.

Interesting to note even with that gaudy K/bb ratio, his FIP was still higher than his ERA. (3.23 FIP, 2.91 ERA) Thats because his walk total was still highesh for the innings he pitched (3.37 bb/9) and he gave up 5 homers in 58 innings.

Going forward, Ollie is a sell high candidate RIGHT NOW. The Velo he regained in 2012 with the Mariners in their pen has dropped back down.

2012 93.7
2013 92.2
2014 91.3

And the velo chart is one of the more inconsistent you’ll see. I think he has more of a chance to collapse than he does of repeating last year.

Good depth often has to come from within, in the form of younger talent. Depth is hard to build overnight, but it’s easy to deplete.: Jeff Sullican

The Tally

  • 5 - Highly Satisfied: 31%
  • 4 - Somewhat Satisfied: 54%
  • 3 - Neither Satisfied Nor Dissatisfied: 11%
  • 2 - Somewhat Dissatisfied: 4%
  • 1 - Very Dissatisfied: 0%

Solid left-handed relief work = solid left-handed scores, with only 4% [likely Mets fans with long memories] giving him below a median score. He did his job, and did it pretty well, seemed to be the consensus of the comments, though several people believe he may not get to finish his contract out in the desert. Whether that means he'll be dealt this winter, or follow Joe Thatcher in being traded as a rental for a few months, remains to be seen.
