Acquired from the Yankees in the Vazquez deal, Michael Dunn was drafted in the 33rd round in 2004 out of a junior college. He was originally used as an outfielder, but after hitting .178 and .086 was moved to the mound. I think that this is fair rare for lefthanders; if they throw hard and there’s any question about their bat, they’re usually going to be pitchers. Anyway, he dominated the rookie league in brief relief work in 2006, then pitched pretty well in the Sally League in 2007 before hitting the wall in 2008 in High-A. The Yankees made him a full-time reliever in 2009, and he pitched well in AA and even better in AAA, earning a promotion to the big leagues, where he got to hang out with multimillionaires for awhile, though he only got into four games and put up a 6.75 ERA.
Dunn throws hard and gets lots of strikeouts, but often doesn’t know where it’s going. He throws a mid-nineties fastball, more than four-fifths of the time, and mixes in a slider — a usual LOOGY assortment. He probably needs to refine the breaking ball to become a top member of that group or move beyond it.
