"Lester will be available tomorrow," Red Sox manager John Farrell said. "Right now, Jake Peavy will start tomorrow. And everybody else is available in the bullpen."
As for more immediate matters, lefty Felix Doubront was a full-go for Game 6 after pitching two innings in Game 3 and another 2 2/3 in Game 4.
Doubront could likely pitch multiple innings again if Farrell needs him for that in Game 6.
"I think so," Farrell said. "Just talking with him yesterday during the workout, he felt good yesterday. That will always be in-game, how things are going, but yeah, multiple innings, I would expect him to be available for that."
A forgotten man when the postseason started -- Doubront didn't pitch in the American League Division Series -- he has become an important piece of late. Doubront was a starting pitcher all season, but he has been able to make a nice transition to relief after showing some initial reluctance.
"[When you pitch] just two innings, you have to give everything you have," Doubront said. "I've been focused and just throwing strikes. It's crazy, you have to be really focused on what you're doing. That's what I did. I just wanted to get quick outs and get out of there. I'm ready."
Game 4 starter Clay Buchholz, who has been dealing with right shoulder weakness, was pinch-hit for in the fifth inning of his start and threw just 66 pitches. He could pitch in Game 6, but Farrell hinted that with a fully-rested bullpen at his disposal, Buchholz would probably be limited to emergency duty.
