First the Pittsburgh Pirates called up one of the best hitting prospects in all of baseball in Gregory Polanco.
Now the Miami Marlins have called up one of the best pitching prospects in southpaw Andrew Heaney. Heaney had a 2.47 ERA, 1.10 WHIP, and 79 strikeouts vs. 15 walks in 76.2 total innings this season between AA and AAA. He projects as a frontline starter, and that time may come sooner rather than later.
