john koronka

Raw data:
year  ORG   level    IP    H    K   BB  HR
2004 CHC AAA 153 164 116 65 19
2005 CHC AAA/MLB 151 154 106 56 14
2006 TEX AAA/MLB 144 164 78 54 19
2007 TEX AAA 35 38 25 13 4
this basically profiles koronka as a bottom of the rotation innings eater in the mold of a mark redman. but is that an apt comparison? here are their comparitive peripheral statistics from 2006:
player     IP   FIP   k/bb   GB%   +WPA
koronka 125 5.24 1.30 42.3 8.63
redman 167 5.04 1.21 44.4 12.47
well, i think we have a match. koronka's WPA added was about 30% less than redman's but he also pitched about 30% fewer innings. koronka has the advantage of being 7 years younger, but he has the disadvantages of being relatively unproven and having his only major league exposure in a hitter friendly environment.

redman's most successful campaign came in 2003 when he played in dolpin stadium with juan pierre and juan encarnacion manning the outfield along with miguel cabrera. the difference between his home era and his road era was about 1.5 runs, and he got slightly hit lucky, having a BABIP 25 points under his career average.

what can he do to improve?

i think koronka could be a moderately effective pitcher if used correctly. his flyball tendencies would play best in a city with a large ballpark and a speedy outfield. specifically, though, there is one thing that i think he needs to improve. assuming there is nothing he can do about his homerun rate due to the environments in which he will pitch, koronka needs to throw his changeup early in the count, especially while he is in AAA.

batters teed off against him when he was behind in the count. if he could turn his changeup into a pitch that he can throw over the plate for a strike, at will, he would benefit from being less predictable as well as from having a pitch that would throw off the rythm of right handed batters.

i like koronka. i think he can be a useful part on a team that is smart enough to put him alongside the right pieces. he's certainly more valuable than esteban loaiza, horacio ramirez, and david wells.
