“I saw him when he was really good at Double-A — throwing BBs at the knees,” said catcher Lucas May. "When he stays down with that very heavy fastball and he finishes, very few people can do what he can do. He’s developing a curve and a change and has a good feel, but he lives off his fastball. When he’s down, he really doesn’t need any other pitch.

“His fastball is heavy — no real sink or cut to it — so when he’s up, he’s hittable. At the knees, he’s tough to hit. The electricity with the fastball is there like [Clayton] Kershaw. The competitive drive is there, too. Kershaw’s curve and change are more developed, but no reason Withrow can’t get there. The second start I caught him at Double-A, after five innings, I came off the field and went over to Dish [pitching coach Glenn Dishman] and said, ‘Watch out for this guy, he could take off.’”
