Quantrill, 22, has a 3.38 ERA and 20:8 K:BB in 29.1 innings since being promoted to Double-A San Antonio.

EDGE Analysis

The stats certainly aren't terrible for Quantrill, though his strikeouts are down and his walks are up since the promotion. Quantrill has made a successful return from Tommy John surgery, though it remains to be seen if his lanky frame will hold up to the rigors of being a starting pitcher, and he must continue the development of a third pitch. Nevertheless, he is one of the better pitching prospects for the Padres.
