2007 Game 18: Minnesota Twins at Kansas City Royals

Ramon Ortiz vs. Jorge De La Rosa

First three times through the rotation, sorted by xFIP:


Dude FIP xFIP GB% K/G BB/G HR/G HR/F
Ortiz 4.07 4.51 40.3% 3.6 0.9 0.91 8.8%
Silva 3.63 4.66 37.1% 4.5 2.0 0.50 4.6%
Ponson 6.72 4.71 56.5% 4.8 3.3 1.90 25.4%

So far this season, the major difference between Ortiz, Silva, and Ponson has been the HR/F rate, which has been shown to be largely (though not totally) out of a pitcher's hands. To me, it says that hitters have jumped on every mistake that Ponson has made, and that Silva and Ortiz have seen their mistake pitches go unpunished. When I looked at the ZiPS projections before the season, I saw three pitchers who were essentially equivalent in value. I still see three pitchers who are essentially equivalent in value.

Some of Ortiz's peripherals that I posted last time moved in the right direction in that last start, but his contact rate went up from 84% to 86%. I don't see Ortiz maintaining much success with that contact rate, but who knows...

Jorge De La Rosa has been one of those Nuke LaLoosh-style pitchers who gets a lot of strikeouts, but also allows a ton of walks. Except that last year he didn't really get all that many strikeouts, either. In his first three games this season, his walk rate is way down. Has he turned a new leaf? I'm awfully skeptical.
