CBS Sports' Scott Miller reports that the Cardinals are hoping that Chris Carpenter (shoulder, neck) is able to join the starting rotation in late June or early July. Carpenter was originally considered unlikely to pitch this season due to a lingering nerve condition in his shoulder and neck. However, he has been encouraged by his throwing program and has suddenly progressed from an option for the bullpen to the starting rotation. The 38-year-old has already stretched himself out to 80 pitches and could begin facing live hitters next week if all goes well. The Cardinals aren't counting on anything, but his unexpected return would provide a major boost for a club which will likely be missing Jaime Garcia (shoulder) for a while.
