ST. LOUIS — The Red Sox said again on Friday that righthander Clay Buchholz, who is dealing with a sore right shoulder, will start Game 4 of the World Series on Sunday.
Buchholz threw in the outfield at Busch Stadium and is scheduled to throw his usual short bullpen session on Saturday.
Manager John Farrell and head athletic trainer Rick Jameyson kept a close eye on Buchholz as he threw.
"He went through a throwing program today. Went back to about 100 feet with some increased intensity along the way, and he's starting Sunday," Farrell said.
For several days, Buchholz's throwing was done under medical supervision of some sort. He also has been receiving daily treatments.
General manager Ben Cherington said Buchholz did not suffer any sort of setback but has what essentially is arm fatigue related to his missing three months.
"From everything I understand, we're confident that he will pitch," Cherington said. "There's no reason we think he can't."
Cherington said Buchholz has more discomfort than an injury.
"He would not be pitching if that was a concern," Cherington said.
Lefthander Felix Doubront has been preparing to make the start in case Buchholz is scratched. Doubront has not started a game since Sept. 22 but has told the Sox he could go five or six innings.
Buchholz said Wednesday that he would not start if he did not feel he could help the team. But he did not expect that be the case.
Teammate Jake Peavy expects Buchholz to start.
"I think you could just physically have to not be able to play the game of baseball to not go out there and compete in this environment, when the adrenaline and the atmosphere can help you through a lot of that as well as maybe some drugs," Peavy said.
Peavy's comments drew laughs. But the Red Sox well could give Buchholz an anti-inflammatory injection to help get through the game.
