Boston Red Sox right-hander Clay Buchholz underwent successful meniscus surgery on his right knee on Tuesday.

Dr. Peter Asnis performed the procedure at Massachusetts General Hospital.

Buchholz, who pitched six innings in Boston’s final game against the Yankees on Sunday, finished the season with an 8-11 record and 5.34 ERA -- the worst ERA of any starter in the league. According to GM Ben Cherington, Buchholz pitched with the injury during the season.

“This is something that he's had some off-and-on symptoms for some time now,” Cherington said on Sunday. “Not something that prevents him from pitching, but we just want to use the offseason to take care of this. It's a relatively routine procedure. Pretty quick recovery, shouldn't affect his offseason."

Cherington maintained that the meniscus issue had no impact on Buchholz's performance.

"It was not a debilitating issue," Cherington said. "It was something that he managed. I think he would tell you that it did not affect him. We're just trying to be proactive so that it doesn't turn into something bigger."
