Lance Berkman left Tuesday's game in the third inning after being hit on the right knee by a Clayton Kershaw breaking pitch. It's the same knee that he had surgically-repaired earlier this season. Berkman went down in a heap immediately and was in obvious pain. He initially stayed in the game but was running very gingerly from first to second on a single, at which point the Cards took him out and inserted Matt Carpenter. He likely just has a bruise, but it wouldn't be surprising to see him sit out a day or two given the Cards' glut of hitting options.
