Bailey's ailing biceps may need more time

ARLINGTON -- In a bit of a surprise, closer Andrew Bailey was not available for Saturday's game against the Rangers. The club determined Bailey wouldn't be able to pitch after he threw before the game.

Manager John Farrell felt Bailey could have pitched in an emergency situation on Friday and was anticipating a Saturday return for the righty.

But Bailey needs a little more time to recover from a right biceps injury that has prevented him from pitching since April 28.

"I went out, and played catch normally and I guess it's not ready yet," Bailey said. "I'm very frustrated. I just have to wake up tomorrow and see how it goes."

However, there's a chance the Red Sox might have Bailey take it easy on Sunday, and then have the medical staff examine him when the club returns home Monday.

"At some point we'll have to get him looked at, most likely, first thing Monday morning," Farrell said.

As it turns out, only one save situation has presented itself during Bailey's absence. Joel Hanrahan, who opened the year as Boston's closer, handled that one cleanly.

In 13 games this season, Bailey has a 1.46 ERA and has held opponents to a .140 batting average.

Breslow sharp in rehab assignment, nearing return

ARLINGTON -- Lefty reliever Craig Breslow made the fifth appearance of his Minor League rehab assignment on Saturday, firing a scoreless inning for Triple-A Pawtucket in a game against Durham. Breslow struck out one.

Breslow was sidelined by shoulder tendinitis that developed during Spring Training and hasn't pitched for the Red Sox this season.

He could be activated soon, perhaps by Monday, when the Sox open a homestand against the Twins.

"He's certainly getting closer," said Red Sox manager John Farrell. "Certainly we'll review that internally and determine if that's going to be when we return immediately on the homestand, or is there an additional need for another appearance? Still, the most important thing is, with each outing, he's gotten more crisp with all his pitches and moving in the right direction."

With Franklin Morales also sidelined, Andrew Miller has been Boston's lone lefty in the bullpen.

The return of Breslow could give Farrell a significant advantage with in-game strategy.

"Well, it gives you the ability to match up if you need to earlier in the game," Farrell said. "Craig is a proven mid- to late-inning reliever. So any time you can add that experience and that performance level, that's going to be a good thing. However, we can't look past what Alex Wilson did for us last night, giving us the nearly three innings of work. So Craig's return to us, as we mentioned with Joel's healthy return, will continue to give us a boost."

Doubront to make next start against Twins

ARLINGTON -- Despite a shaky performance by Felix Doubront on Friday and some overall inconsistency in the early part of his season, the lefty will make his next scheduled start on Wednesday night against the Twins, manager John Farrell confirmed.

"Then you're talking about a complete adjustment to the roster with no off-days," Farrell said. "[Skipping a start] hasn't been contemplated right now in this next turn."

Doubront's arm strength doesn't seem to be what it was in the past, at least according to the radar-gun readings.

The Red Sox continue to find nothing wrong with Doubront from a health standpoint.

"Yes, same as he came out of last night's game," Farrell said. "No additional soreness or anything unforeseen."
