After a month and half away because of tightness in his throwing forearm, the right-hander returned with 1 1/3 scoreless innings to end Saturday's 9-2 win over the Red Sox at Fenway Park. The 35-year-old faced five batters, struck out two and gave up one hit on 25 pitches, just eight of which were balls.
"We wanted to be careful with an up and down [pitching across multiple innings], but he felt great and threw the ball as you saw," manager John Farrell said.
Before the game, Farrell said part of the logic that had kept Frasor out of action was that he wanted to find the right situation for him having not pitched in a big league game since July 16.
"Frasor's been a very good reliever for a long time and still has a lot of pitching left in him," Farrell said. "The fact is we've got more options available to us. We're still lining up to win every single night and yet his situation, his coming back, we want to get him where he's got his feet back on the ground, regardless of the stage in his career. But there's no lack of confidence in getting him on the mound."
