Perez held the Rockies to a single run on four hits and two walks over 5.2 innings Wednesday. He struck out three and didn't factor into the decision.
Perez has been putting on a Jekyll-and-Hyde act lately; over his last seven outings, he's allowed five or more runs five times, but has limited the opposition to a single run in the other two. His K:BB is still awful at 70:60 over 145 innings, and although his groundballing ways allow Perez to have a modicum of success here and there, that plentiful contact he surrenders always catches up to him in the end.
