Giolito, 21, has posted a 3.82 ERA, 1.65 WHIP and 30:22 K:BB ratio over 35.1 innings at Double-A Harrisburg.
Giolito's control has been shakier than advertised through his eight starts with Harrisburg, but he's at least receiving the green light to begin working deeper in games. After having not thrown more than four innings in his first five starts of the season, Giolito has gone at least five innings in his last three turns.
