BP Annual Player Comments

YearComment
2010 Journeyman John Koronka joined the Marlins on the rebound from Japan and got called up when a hot start at New Orleans happened to coincide with Anibal Sanchez's injury; he was soon deselected for Sean West.
2007 Koronka was doing a credible job as a back-end rotation man until the All-Star break when the wheels came off the cart. Several rough outings later and he was sent back to the OKC. Koronka hasn`t been much better against lefties than righties, so a bullpen specialist role is right out. What seems more likely is trash time middle relief/Kevin Jarvis work as a desperation starter. Anything he does beyond acting as a place holder would be gravy. Still, he`ll get a shot at the rotation again in 2007.
