Yeah, well, I didn’t know about the guy either, but Orix conitinue to scrape the bottom of the barrell with their attempts to sign some import pitchers (some tryouts earlier in the season didn’t work out, if I remember correctly). Koronka’s career minor league stats are 4.36 ERA, 6.75 K/9, and 3.94 BB/9. His cumulative MLB record from 2005-07 (mostly accumulated in 2006 when he was part of the Texas Rangers rotation for part of the season) is an avert your eyes 6.02 ERA, 4.35 K/9, and 3.58 BB/9 (though with a small sample size warning of 151 IP). If he manages to earn some playing time with the big club I expect his numbers to fall somewhere between his minor league and MLB numbers, as generally NPB is regarded to be about AAAA level.
The Buffaloes continue to grasp at straws after their Jeremy Powell fiasco (JP officially signed with the Fukuoka SoftBank Hawks while Orix management were twiddling their thumbs with an informal offer), but then again what can you expect from talent that’s available midseason, and also the Orix bumbling management. But, there is a chance that Japanese waters suit Koronka so well that he succeeds (or at least be useful) in NPB. So, if he’s a cheap signing (likely will be) then I guess it’s a low risk scenario (though I have about 95% doubt that it’ll pan out).
