    View Draft Report
    A draft-eligible sophomore, Heasley's results haven't matched his stuff. He can touch 94-95 mph with his fastball, his power slider can earn above-average grades and he mixes in a below-average curve and change as well. But he's proven very hittable this spring as he's moved from a relief role to a spot in Oklahoma State's rotation. Heasley's below-average control needs to improve. He was 3-6, 6.72 at the end of the regular season with 86 hits allowed in 71 innings, 36 walks and 72 strikeouts.
