Had to go to the media guide for this guy, as I've never heard of him. He's a 6'5" 185 lbs (skinny!) 25 year old left hander who has been mostly a reliever in the minors, never above A ball. Trying to figure out why he's been added to the 40 man roster, maybe it's because in 190.2 innings pitched over four years, he's struck out 191 with an overall 3.21 ERA. Maybe he's replacing Koronka in same grand scheme. If that isn't it, then I'm stumped.
