ST. LOUIS — Three games into his Cardinals career, Mark DeRosa is hurt. He and the club are just hoping it’s not too serious.

DeRosa injured his left wrist on a swing in the fourth inning of St. Louis’ 6-3 loss to San Francisco on Tuesday night. He remained in the game for one more inning, but removed himself before taking another at-bat. He is expected to be re-examined on Wednesday.

"I took a swing there my second at-bat and felt a little tweak in my left wrist," DeRosa said. "I went in to hit off the tee after coming in from playing the field, and it just didn’t feel right. I felt like I should come out of the game and get it looked at."
