Hampton's rotator cuff surgery a success

Astros expect oft-injured southpaw to miss 2010 season

CINCINNATI -- Left-hander Mike Hampton will miss the entire 2010 season after undergoing surgery Tuesday morning to repair his left rotator cuff. The surgery revealed Hampton had a full tear of his rotator cuff and as well as damage to his labrum.

Astros general manager Ed Wade received the report Tuesday morning from Mark Rodgers, Hampton's agent. Wade said Dr. David Altcheck at the Hospital for Special Surgery in New York City found a full rotator cuff tear and a "big hole" in his rotator cuff.

"He's not to pick up a ball until January or February of next year and will not pitch in 2010," Wade said.

Hampton, 37, went 7-10 with a 5.30 ERA in 21 starts this year for the Astros, who signed him to a one-year, $2 million contract in the offseason. Various injuries, especially Tommy John elbow ligament replacement surgery, limited the left-hander to just 25 Major League starts from 2005-08.

Hampton said recently he also wants to have arthroscopic surgery on both knees at some point in the offseason.

"Obviously, he was trying to battle through all these issues that he's got and plus he's got the knees, and we haven't talked about that yet," Wade said. "It's unfortunate."

Wade said Hampton will likely join the team next week in Houston.
