BOSTON -- Lefty Craig Breslow has been unable to find the form that made him one of the most reliable relievers the Red Sox had last year.

Breslow has pitched in 29 games, posting a 5.40 ERA. Opponents are hitting .296 against him. Manager John Farrell doesn't believe the lefty is injured.

"Two nights ago, I thought he was throwing some of his better stuff of late. There's been multiple conversations on more approach, rather than physical side that might play into the number of walks," said Farrell. "I thought he was more aggressive the other night and yet there were a couple of base hits were when he was ahead in the count. But we're still trying to seek some consistency with the performance."

In essence, the Sox would like Breslow to trust his stuff more.

"I think more just in terms of being aggressive overall rather than thinking there's got to be a perfect pitch made each time," Farrell said.

Could it be that Breslow is feeling the after-effects of a long season in which the Red Sox went all the way to the World Series?

"Well I can't say that October doesn't have a carryover effect for every guy, regardless of position," said Farrell. "You take all that into account. The one area of greatest unpredictability is the bullpen from year-to-year performance. There's no injury, he's pitched a lot over the last four or five years. All I can speak to is there are no physical ailments right now that specifically he's dealing with."

BOSTON -- Red Sox manager John Farrell is looking forward to knowing what his All-Star roster will look like once the squad is unveiled Sunday. In the meantime, he's doing what he can to keep the candidates on his team updated.

"Given all the information we've received over the last three days, you kind of keep guys apprised of who would be in consideration, what scenarios may or may not play out like," said Farrell. "You deal with them as straight up as possible and know that guys in our uniform did an awful lot last year for us to be in this position to be able to go to Minnesota. You keep that in mind, but I think guys recognize, too, that they're voting members, so they see years that players are having and they're realistic in their own right."

Fans vote for the starters, while players from around the league select the reserves and most of the pitchers.

Farrell selects seven players, in conjunction with Major League Baseball.

"But you have to take into account a number of factors," Farrell said. "Every team being represented; we're mandated to have a 13-man pitching staff. There are a few things that kind of narrow down your overall selections."

Brock Holt, who has come out of nowhere to have a solid season for Boston, is one intriguing candidate.

"There's been some conversation about him, and yet because of the other factors just mentioned, you don't have carte blanche to have a 34-man roster," Farrell said.
