You can't dismiss the tendency to give up the long ball. Especially the fact that most of them (13 of 16) occured from the 4th inning on. His OPS against goes from .588 in innings 1-3 to .828 in 4-6 and a whopping 1.444 from the 7th on. Thats a formula where games get turned suddenly and contributes to his win total being so low along with poor run support and shoddy relief. His stuff is different, but Dave Bush had a similar tendency. I like Estrada, but I think he'd more have more value coming out of the pen. Pogo, I'm with you on this one. JB, you make good points, however there are three other things to consider: 1) Bouncing Estrada back and forth between the rotation and pen and the rehab stint has likely caused Estrada to not be fully stretched out at times. The significantly higher OPS-A in the later innings might be caused by this. B) Moving him to the pen assumes that there are better starters available. I'm sure most pitchers would probably make better relievers than starters. However you want your best pitchers pitching the most innings - i.e. being your starters. If there aren't five better starters in spring training, then he should be a starter. Pogo you're right, Estrada statistically has earned a starting spot more so than Rogers. And while Peralta has been on a nice run lately, his overall body of work for 2012 suggests he hasn't earned a starting spot over Estrada either. 3) Looking at his 3-year splits from 2009-2011, Estrada had a higher OPS-A as a reliever (.733) than as a starter (.719). For his career, it is almost equal - .750 as a reliever vs. .752 as a starter. For his career, as a starter he has given up 21 HRs in 551 PAs (1 per 26.2 PAs) and as a reliever he has given up 14 HRs in 376 PAs (1 per 26.9 PAs). So statistically it looks like he is roughly the same pitcher as a starter as a reliever, maybe slightly better as a starter. My prediction: 1) Gallardo 2) Free agent (Marcum or other, not Grienke) 3) Fiers 4) Estrada (actually well above average for a #4) 5) Rogers (allows them to skip his turn occasionally to gradually increase his innings)] Peralta, Thornburg, and Burgos in AAA as insurance.
