BOSTON -- After allowing five runs on four hits in one inning of relief in the Rays' 13-5 loss to the Red Sox on Saturday, Dane De La Rosa was optioned back to Triple-A Durham, and the club recalled right-hander Alex Cobb on Sunday.

Cobb was 0-1 with a 2.25 ERA in two starts for the Bulls this season. He made 12 starts with Durham and nine for the Rays over three stints in the Major Leagues in 2011. Logging his first experience in The Show, Cobb was impressive while posting a 3-2 record with a 3.42 ERA. On Aug. 18, he had season-ending surgery to remove a blood clot and blockage in the area of his first right rib.

"Arm feels good," Cobb said. "That's all I was really concerned about going into the year after the surgery. The arm's healthy. The [velocity is] coming back a little bit, so everything is going well. I'm pitching just like I would any other year."

Entering Sunday afternoon's contest with the Red Sox, the Rays' bullpen was running on fumes after a busy week. Manager Joe Maddon said they will be looking for Cobb to give the bullpen some length.

"I wasn't expecting to be back this quick, and in a reliever role, which is what it looks like I'll be in," Cobb said.

Cobb had been scheduled to start for Durham on Sunday.

Gimenez promoted, starts Sunday vs. Red Sox

BOSTON -- Chris Gimenez arrived Sunday morning to take the place of catcher Jose Lobaton, who went on the disabled list with a sore right shoulder. Gimenez was hitting .375 with an RBI in two games at Triple-A Durham.

"Things like these you always have to be ready for whenever the case comes up," said Gimenez, who got the start behind the plate and batted ninth vs. the Red Sox. "It's just like we talked about -- you have to go down there and do your work, because you never know when that opportunity is going to arise. And hopefully you take advantage of it."

Gimenez had been on the seven-day disabled list with a testicular bruise. He said surgery had initially been a possibility when they weren't sure if the testicle was ruptured.

"It was kind of unfortunate, wrong place at the wrong time," Gimenez said. "It was a tie game in the ninth inning with the bases loaded. It was a fastball [from Cesar Ramos] in the dirt. I tried to do everything I could to block it. It was just one of those where it kind of skipped and missed me in the glove and hit me perfect, right in the right spot. And it was extremely unpleasant."

After incurring the injury, Gimenez said he was restricted for three days.

"They didn't want me doing anything," Gimenez said. "It was an unfortunate accident, didn't feel very good. But it was kind of funny they put 'groin strain' on the official report. That was funny."

Manager Joe Maddon said the possibility exists for Gimenez to play and win the backup catcher's role. Gimenez views his callup as an opportunity.

"I mean, every time you get a chance to go out and play, it's an opportunity," Gimenez said. "I mean, am I looking at it as a battle? No. I'm just trying to do what they're asking me to do every day that I'm in there. If I can just take care of business and take advantage of the opportunities that I do get, let that maybe lead to where it leads.

"I told them I'm here to do whatever you want me to do, whether that's play outfield or infield or catch. Whatever the case may be, or sit there and be a good teammate."

Extra bases

• Entering Sunday's game, Rays pitchers had walked 38 batters (11 have scored), which is the most in the American League. In addition, the total is the most by a Tampa Bay staff after eight games since 2003.

• B.J. Upton (lower back soreness) played in his fourth rehab assignment game with Class A Charlotte on Saturday night and went 0-for-4 in Charlotte's 2-1 win over Jupiter. Manager Joe Maddon said Sunday that Upton is headed for further rehab action at Double-A Montgomery. Maddon does not expect Upton to be big league ready before the end of the Rays' current road trip.

• Maddon will be featured on HBO Real Sports with Bryant Gumbel in a segment on its 2012 premiere Tuesday at 10 p.m. ET. Armen Keteyian interviewed Maddon for the piece.
