Carpenter was removed from Monday's game against the Padres due to right shoulder tendinitis, Derrick Goold of the St. Loius Post-Dispatch reports.
Carpenter appeared to injure himself while striking out in the top of the fifth inning, and he was subsequently replaced by Alex Mejia before the bottom half of the inning. This issue likely explains his absence over the weekend, as Carpenter was withheld from the starting nine on Saturday and Sunday with no explanation. More should be known about the severity of the ailment following the conclusion of Monday's contest.
