Theriot was hit on the left shin by a Randy Wolf pitch in the first inning. When he got to second base following a Colby Rasmus single, the Cardinals' training staff came out to check on him, but he remained in the game. Theriot took another at-bat, singling in the third, before being removed.
"It just got a little bit more sore as it went on," Theriot said. "I kind of wanted to see if it would loosen up as the game went on. But it didn't."
Daniel Descalso pinch-hit for Theriot with two outs in the fourth, and was also hit by a pitch. Theriot joins a list of ailing Cardinals infielders, as second baseman Skip Schumaker and third baseman David Freese are on the disabled list.
