Foster Griffin

As a 6-foot-3 left-handed pitching prospect, Griffin showed the Royals enough upside for them to select him 28th overall in the 2014 first-year player draft. He went on to post a strong 3.21 ERA during 28 innings of rookie ball, but was helped out a bit by a 75.3% strand rate and uncharacteristically-low .210 BABIP. At just 19 years old, Griffin has plenty of time to develop his secondary pitches, and should be able to improve upon an upper-80s fastball as he moves through the ranks of the farm system. He projects as a strong lefty reliever at the big league level, with a chance to evolve into a mid-rotation option if he can display more consistency with his curveball.
