Cardinals Chris Carpenter undergoes surgery

Two to three month rehabilitation period anticipated

ST. LOUIS, Mo --  St. Louis Cardinals pitcher Chris Carpenter underwent neurogenic thoracic outlet surgery earlier today in Dallas, Texas.  The procedure was performed by Dr. Greg Pearl.

Carpenter, 37, will remain in Dallas for recovery the next couple of days before returning to St. Louis to begin his rehabilitation.  The anticipated time of rehabilitation is 2-to-3 months and Carpenter should be fully able to have a normal off-season in preparation for the 2013 season.

“We are pleased with today’s results and Chris will soon return to St. Louis to begin his rehab,” said Cardinals Sr. Vice President/General Manager John Mozeliak.  “We look forward to seeing Chris around the ballpark during his recovery.”
