JUPITER — Cardinals ace Chris Carpenter won't start opening day after a setback in his recovery from a bulging disc in his neck.
The right-hander, 37, returned to St. Louis on Tuesday for tests. He threw live batting practice Sunday but didn't feel right the next day.
"He looked really good and felt good; the next day he just didn't respond like we had hoped," manager Mike Matheny said Wednesday. "His shoulder is just not responding and they're uncertain of the root of it. That's what they're trying to get to with tests on the neck and shoulder and trying to figure out where it's all coming from."
Right-hander Kyle Lohse will start April 4 at Miami in his place. Lohse was 14-8 with a 3.39 ERA last season, leading the Cardinals in wins and ERA.
"It's an honor," Lohse said. "But it comes meaning that Carp's not available; that's the tough part about it. I wish it were under different circumstances, but I'm proud to take the ball on opening day."
Right-hander Lance Lynn, a setup man, will take Carpenter's spot in the rotation.
