Andrew Heaney, LHP, Oklahoma State University: Listed at 6-2, 175, Heaney saw his fastball bump as high as 95 MPH this spring, to go with his already-strong slider and changeup. He went 8-2 in 15 starts this spring, with a 1.60 ERA and a 140/22 K/BB in 118 innings. His velocity boost convinced scouts that he can be more than just a strike-throwing efficiency expert., and he was considered the top left-hander available from the college ranks. He instantly becomes the most advanced pitching prospect in the Marlins' farm system, and should be ready to contribute in the majors within two years. He projects as a number-three starter, but a reliable one. Heaney was projected anywhere from ninth to 20th on pre-draft mock boards by the various experts. Oklahoma State isn’t the easiest environment in which to pitch, but Heaney certainly proved his moxie and mound presence in the Big 12.
