A Dominican who will probably be most-remembered for being one of the prospects traded for new Miami manager Ozzie Guillen, Jhan Marinez is a bit of an under-the-radar sleeper prospect now in the White Sox system who doesn't get as much attention as he probably deserves, despite his appearance in the Futures Game last season. Marinez is a slight player with a power fastball that can touch 98, but he has more success with his two-seamer, a 92mph offering with exceptional movement. His change and slider still need to improve before they're ready for the big stage, but he has so much raw talent that he's bound to make it sooner or later.
