ST. PETERSBURG, Fla. – All-Star pitcher Clay Buchholz of the banged-up Boston Red Sox is going on the 15-day disabled list because of a strained left hamstring.

Buchholz, 10-4 with a 2.45 ERA in 15 starts this season, is expected to be at next week’s All-Star game, but will not participate.

Buchholz was hurt while running the bases June 26 in San Francisco.

Red Sox Manager Terry Francona made the announcement before Monday night’s game at Tampa Bay.

Buchholz could return to the rotation right after the All-Star break.

“We just weren’t comfortable about the running part,” Francona said. “There’s no reason for us to rush it.”

The Red Sox put catcher Jason Varitek and reliever Manny Delcarmen on the disabled list last Friday — at that point, 10 Red Sox players were on the DL, including Josh Beckett, Dustin Pedroia and Victor Martinez.

Left-hander Felix Doubront is being recalled from Triple-A Pawtucket to replace Buchholz as the starting pitcher for tonight’s game with the Rays.

He won his major league debut June 18, allowing three earned runs over five innings in Boston’s 10-6 win over the Los Angeles Dodgers.

“I feel more confident, more relaxed this time,” Doubront said.

Beckett, on the disabled list since May 19 with a lower back strain, is scheduled to pitch in a rookie-level Gulf Coast League game today with a limit of about 55 pitches.

If recent rainy weather in Florida continues and the GCL game is postponed, Beckett would instead throw a simulated game at Tropicana Field against Red Sox minor leaguers.
