Diamondbacks starter Wade Miley experienced a drop in velocity during his last outing Friday night against the Padres.

Miley, who gave up four runs on nine hits in five innings, watched video of his start in an attempt to understand what went wrong.

"Mechanics weren't too bad," Miley said to MLB.com. "Might have been rushing, flying open a little bit. Nothing major."

Miley is projected to make his next start Wednesday at the Dodgers. He is 2-0 with a 2.11 ERA in his last three starts at Dodger Stadium.
