Clay Buchholz sidelined with back soreness

BOSTON -- Red Sox pitcher Clay Buchholz suffered a lower-back injury while throwing a bullpen session on Friday and will not make his scheduled 29th start of the season on Saturday against the New York Yankees at Fenway Park.

The right-hander (17-7, 2.33 ERA) was throwing his normal session the day before a start when he felt his lower back “grab” at him. He came off the field and met with head trainer Mike Reinold and manager Terry Francona and it was decided it would be best to shut him down.

Buchholz admitted this is something he’s been dealing with for the past month.

“I would like to throw another [game],” he said. “[The back soreness] has been there for the last five or six starts. It might have something to do with the cold weather. [Monday in Chicago] was the first cold game I’ve pitched in a while, and I had a couple of innings I was in the dugout a little bit longer and then cranked it back up to 100 percent once I got off the bench. It was one of those that’s in a sensitive spot.”

It’s likely veteran knuckleballer Tim Wakefield will start against the Yankees on Saturday.
