Medeiros, 21, has a 5.27 ERA and 58:21 K:BB through 56.1 innings for High-A Carolina.
The strikeouts are nice, but Medeiros has allowed a few too many baserunners, resulting in a bloated ERA. In addition, he has been allowing fewer groundballs than ever before. In fact, he's already allowed as many home runs this season as he did all of 2016.
