Castillo unveiled a two-seam fastball three weeks ago to go with a four-seamer, changeup and slider. He used the two-seamer the most over his six scoreless innings Tuesday and allowed two hits. His quick command of his four pitches has impressed.

The rookie southpaw’s fastball command has improved over his past two starts, but he still had to pitch around four walks while allowing three solo homers Tuesday at Coors Field. He has not used his slider in either of his past two starts.
