Quintana throws his four-seam fastball way too much (48%, more than any other pitch). It’s a below-average fastball by every metric you can think of: velocity (91.1), spin rate (2,029 rmp) and batting average allowed (.299). Only Chad Bettis of the Rockies has less spin on his fastball than does Quintana. In addition, Quintana has an easy delivery to time with no deception and no tilt in his shoulders to create life and leverage on the ball.
