Cards put Carpenter on DL
Boggs likely would fill Carpenter's spot in the rotation. Perez was one of three pitchers competing for the closer's job in spring training.
Carpenter was injured grounding out to third base to end the top of the fourth inning Tuesday night against the Diamondbacks. He called for a trainer after warming up before the bottom of the inning.
Carpenter missed virtually all of the last two seasons with elbow and shoulder injuries. He was the NL Cy Young Award winner in 2005.
