Astros ace Justin Verlander left his start on Sunday after three innings and 60 pitches, with the team later announcing he has right calf discomfort.

Verlander struck out six and allowed three hits and one walk to the visiting Orioles before departing his shortest outing of the season. The game was scoreless at the time.

 "He's going in for some imaging [Monday]," Houston manager Dusty Baker said. "He felt that -- when he was covering first base -- that it was his calf. And that is the best of bad news. We were really glad that it wasn't anything to do with his arm or elbow or anything like that."
