Heaney’s draft stock has been surging all spring, as he’s emerged as the top left-handed collegiate arm in the 2012 draft class. He sets up all of his offspeed pitches with a 90-95 mph fastball that has late, arm-side action. Furthermore, he throws it with conviction to both sides of the plate.

Much like last year’s top college southpaw, Danny Hultzen, Heaney has fluid and repeatable mechanics and throws the ball with minimal effort. He has a quick release that’s capable of working at several arm slots, though he typically throws from a high three-quarters angle.

Heaney has also shown above-average command of his 79-83 mph curveball and 83-87 mph changeup, which adds to his overall game. His mechanics are smooth and repeatable, and his quick arm adds deception to all his pitches.

His arm angle and ability to manipulate both pitches have drawn comparisons to C.J. Wilson, though it’ll be interesting to see how he handles a heavy workload in the major leagues. He won’t be a fast riser like Hultzen, but Heaney could reach the major leagues by late 2014.
