PHILADELPHIA (AP) - St. Louis Cardinals right-hander Michael Wacha has left Wednesday's start against the Philadelphia Phillies with a left oblique strain.
Wacha exited the game in the bottom of the fourth. He allowed three runs - one earned - in 3 2/3 innings.
Wacha surrendered a two-run homer to Cesar Hernandez and pitched to one more batter before he was replaced by Mike Mayers.
