Cardinals' Chris Carpenter Out Indefinitely With Nerve Inflammation

Cardinals hurler Chris Carpenter has undergone a series of medical exams in St. Louis over the last four days, and he's received a diagnosis for the weakness in his right shoulder -- the hard-throwing righty is suffering from nerve inflammation, according to

The nerve inflammation is entirely separate from the other issue with Carpenter's shoulder, a bulging cervical disc that was bothering him earlier this month. As a result of Carpenter's various ailments, the team has decided to keep Carpenter out indefinitely. He's unlikely to be ready for Opening Day.

"I know it's not great news," Cardinals manager Mike Matheny said. "We still don't know exactly how to take it."

Carpenter pitched 237.1 innings last season, tops in the National League, plus an additional 36.0 in the postseason as he helped the Cards win the World Series for the second time. Spring training has been slow for the 36-year-old -- he threw to batters on March 3 and has been shut down in the weeks since.
