Jason Stoffel

The 6-foot-1, 225-pound Stoffel looked like a no-doubt first-rounder entering the season, and while he still flashes a fastball that sits 93-95 mph and a slider that can be unhittable, he has been inconsistent. His fastball and slider have straightened out and lost a few ticks at times this season, and his numbers this season aren't those of a dominant reliever. But Stoffel became Arizona's career saves leader this season with 26 and counting, passing Mark Melancon. Scouts who have seen him good put Stoffel in the same class as Arizona's first-round pitchers from last season, Ryan Perry and Daniel Schlereth. He's a fierce competitor but falls into the trap of many relievers in pitching to the situation. He pitches better in close games, and can lose focus when he comes in with a cushion. Some question Stoffel's decision to pass on pitching in the Cape Cod League or for Team USA the past two summers.
