With strained arm muscle, Joba hits DL

Reliever unlikely to return when eligible in 15 days

NEW YORK -- Joba Chamberlain's right arm had been tender for the past couple of weeks, but not so much that Yankees manager Joe Girardi felt uncomfortable with having the right-hander throw 35 pitches against the Angels on Monday.

On Wednesday, Chamberlain was placed on the 15-day disabled list after an MRI exam in the morning revealed a strained flexor muscle in his throwing arm. He is not to resume throwing until 10-14 days have passed, and he won't be able to return after just 15 days down.

"It just gets tight," Chamberlain said. "There's no pain. You can do whatever you want to, it's just that as soon as I'm done throwing, it just gets tight."

"We've been careful with him in what we've done; he played catch yesterday, and he just said it feels pretty good today," Girardi said. "But it's been tender, and we had the doctor look at it. We decided to do an MRI this morning, and that's what he had."

Based on what he knew of Chamberlain's condition, Girardi said he would not have used Chamberlain differently. Girardi also said that Chamberlain would not need any more invasive treatment unless there was a setback.

"He'd been getting treatment on his elbow for a couple weeks, which is not really abnormal for a pitcher to ice after games," Girardi said. "After games at times, he'd be a little bit stiff, and there's days that we stay away from people. But his stuff had been really good and he had pitched really well, which didn't lead us to believe that he really had an issue."

The Yankees' bullpen, already down a key piece with Rafael Soriano on the disabled list, now becomes even more of a patchwork assembly. Chamberlain's move to the DL was one of four roster moves New York made before the second of three games against the Red Sox, all involving relievers.

The trickle down leaves David Robertson to take eighth-inning responsibilities in front of closer Mariano Rivera, and Luis Ayala and Boone Logan likewise will be asked to step up.

Right-hander Hector Noesi was optioned to Triple-A Scranton/Wilkes-Barre because he would have been unavailable for a few days after throwing six innings in relief of an ineffective Freddy Garcia on Tuesday night.

In place of Chamberlain and Noesi came right-handers Amauri Sanit and Jeffrey Marquez. Sanit, 31, made three relief appearances for the Yankees last month -- the last on May 19 -- the longest for 4 2/3 innings.

Marquez, 26, was a supplemental first-round Draft pick of the Yankees in 2004, and he returns to the organization on a waiver claim from the White Sox. He arrived at Yankee Stadium shortly before 6 p.m. ET, having been designated for assignment by Chicago on Sunday. Marquez's contract was purchased by the White Sox on May 30, but he did not appear for them this season.

Marquez's only career Major League appearance came last season with the White Sox, and he had spent this season with Chicago's Triple-A affiliate in Charlotte. He was 3-4 with a 3.97 ERA in nine starts and threw one shutout.

Marquez last pitched for the Yankees in 2008, at Triple-A.

Noesi has allowed three runs in 15 1/3 innings this season, spanning four appearances and two stints with the team.

"He did everything that we could ask of him," Girardi said of Noesi. "His performance was outstanding, especially for a young kid, because he was thrown in some tough situations. ... It really came down to, we needed some arms."

Knee 'remarkably better,' Teixeira returns

NEW YORK -- After writhing in pain on Tuesday night when a Jon Lester cut fastball hit his right knee, Yankees first baseman Mark Teixeira returned to the starting lineup and the field on Wednesday, the discomfort manageable.

"The pain is still there, but it's very tolerable," said Teixeira, who batted third against Red Sox knuckleballer Tim Wakefield in the middle game of three. "It feels so much better because there's no swelling in there."

Teixeira credited his fast return to how quickly the knee was treated on Tuesday night after his first-inning exit. He kept a wrap on the knee through the night, and despite not sleeping well, he woke up feeling better and texted manager Joe Girardi, saying he was good to go. Teixeira wore a compression sleeve on the knee Wednesday.

"I didn't know what to expect, because sometimes it's worse the next day," Teixeira said. "It's remarkably better."

Teixeira said there was no discussion of him DHing, and he tested the leg with some dry swings and basic activities.

Though Teixeira was one of two Yankees whom Lester hit on Tuesday -- along with Russell Martin -- and Red Sox veteran David Ortiz dramatically flipped his bat after homering, Girardi said he did not hear talk of bad blood carrying over past Tuesday.

"I didn't hear our guys talk about it at all," Girardi said. "It seems like it's been talked about more amongst the media than our guys. I didn't hear anything about it from our guys where they were upset [about] Big Papi's flipping his bat or Jon Lester's hitting two guys. It wasn't a situation where you're going to hit two guys on purpose."

The good news on his knee aside, Teixeira enjoyed some fun earlier in the day at Yankee Stadium. He and Alex Rodriguez shot a scene for the HBO show "Entourage."

"I've never done anything like that," Teixeira said. "I've never done a commercial, I've never done TV, a movie -- anything like that -- but spending an hour out there for a 20-second scene is kind of cool." Teixeira said there were about 10 takes, but he revealed no plot details.

Yanks rest Martin after back locks up

NEW YORK -- Russell Martin's back injury reduced the Yankees' bench to two on Wednesday, when the catcher was out of the starting lineup after his back locked up on Tuesday night.

Francisco Cervelli batted ninth in Martin's place, leaving only outfielders Chris Dickerson and Andruw Jones in reserve for manager Joe Girardi against the Red Sox. Jorge Posada was away from the team on Wednesday because of his son's surgery, and Eduardo Nunez was playing in Posada's place.

A timetable for Martin's return isn't clear, although Girardi made no mention of his starting catcher making a trip to the disabled list.

"When a back locks up, you really don't know," Girardi said. "It could take a couple days, it could take three days. I can't really tell you. It could be tomorrow."

If Cervelli were to be hurt on Wednesday, Girardi said Martin would probably be available, but that if Martin wasn't, Girardi was not sure to whom he'd turn. Martin expressed interest in trying to play on Wednesday, but Girardi nixed the idea.

"He said that he wanted to try to work it out," Girardi said. "And I said, 'You know you can try to work it out and go through treatment, but my guess is you're probably not going to be able to play today.'"

Posada misses game after son's surgery

NEW YORK -- Jorge Posada was not with the Yankees for their game against the Red Sox on Wednesday night in order to spend time with his 11-year-old son, who underwent surgery.

Posada's son, Jorge III, underwent another surgery for craniosynotosis, a birth defect in which the bones in the skull do not fuse correctly. Posada has said he hoped this would be the final surgery for his son, who has had numerous operations.

Although they were without Posada -- who has been used primarily as a designated hitter this season -- the Yankees did have first baseman Mark Teixeira back in the starting lineup a day after he was forced to exit upon being hit by a pitch from Boston's Jon Lester.

It was Posada who entered the game for Teixeira in the first inning on Tuesday. He went on to collect three hits, including his first two against a left-hander this season.

Through the Jorge Posada Foundation, the Yankees veteran and his family have raised money for those affected by the condition.
