Miller likely to miss season with foot surgery

Red Sox reliever was enjoying fine season in bullpen prior to injury

SEATTLE -- Red Sox manager John Farrell revealed before Monday's game against the Mariners that reliever Andrew Miller will need foot surgery, saying that it was "unlikely" the left-hander would return to the bullpen this season.

Miller left Saturday's game against the Angels with a left foot injury. The loss of Miller further depletes Boston's ailing bullpen. The Red Sox lost closer Joel Hanrahan for the season in May and reliever Franklin Morales is on the DL.

Preliminary X-rays taken on Saturday at a hospital in Anaheim did not show a break in Miller's foot. Miller, who was placed on the 15-day disabled list, flew back to Boston on Sunday night to be examined extensively on Monday by the team's renowned foot specialist, Dr. George Theodore

Prior to his injury, Miller had been enjoying one of his best seasons, now in his second full year as a reliever. The former first-round pick in the 2006 First-Year Player Draft was a starter with the Tigers, Marlins and Red Sox, This season, the 28-year old has a 2.64 ERA, striking out 48 batters in 30 2/3 innings. As a starter, his best year was in 2008 with the Marlins, when he went 6-10 with a 5.87 ERA.

"From the role change to the change in his delivery, which has allowed him to repeat a release point more consistently, and really to harness well above-average stuff," Farrell said. "There are many examples of lefties coming along at different points in their career, and he was another example of that happening a little bit later than maybe he first anticipated."

Craig Breslow is currently the only left-handed reliever in Boston's bullpen.

Ellsbury out of lineup nursing sore wrist

SEATTLE -- Outfielder Jacoby Ellsbury wasn't in the Red Sox lineup on Monday night, as he received treatment for a wrist injury sustained late in Sunday's loss to the Angels.

"In his second to last at-bat [Sunday] night, he felt some irritation in the left wrist. He was able to get through last night, was pretty sore afterwards, and has reported today with similar feelings," manager John Farrell said. "Rather than risk anything further, we're giving him a day out just to receive treatment."

Ellsbury is riding a 17-game hitting streak, during which he's batting .389 (28-for-72). He's also been a terror on the basepaths, leading the Majors with 36 stolen bases in 39 attempts.

Farrell said there aren't any immediate plans to have X-rays taken on Ellsbury's wrist.

"We're hopeful that this is something that will respond to treatment. If it doesn't, certainly, every test at that point would be taken," Farrell said.

Boston's outfield depth already is stretched razor-thin. Shane Victorino is recovering from a sore hamstring, although Farrell indicated he would be able to play in an emergency. That means more playing time for Mike Carp, who started in left field on Monday with Daniel Nava in center and Jonny Gomes in right.

"That's kind of a tentative situation, we've got some things to balance and weigh out," Farrell said. "As we get through today, we'll have a better read on how long each case, both for Shane and Ellsbury, will be."

Worth noting

• David Ortiz went 2-for-2 on Monday and needs just four hits to match Harold Baines' Major League record of 1,688 by a designated hitter. Former Mariners great Edgar Martinez is third on the list with 1,607.

• Red Sox starting pitchers had allowed no more than two earned runs in eight straight games before Monday's 11-4 loss. The team went 5-3 in that previous stretch.

• Boston has held first place in the American League East standings for 43 days in a row dating to May 27.
