Zach Cooper

A successful starter at Central Michigan since midway through his sophomore season in 2010, Cooper profiles as a reliever in pro ball. He's just 5-foot-10 and 190 pounds and lacks the command to stick in a pro rotation, but he has the stuff to be a weapon out of the bullpen. He can maintain a 91-93 mph fastball deep into games and has hit 95 in the past, so his velocity figures to increase in shorter stints. He flashed a wipeout slider in the past but it's more of an average pitch now, occasionally flattening out. The Marlins drafted him in the 46th round a year ago.
