BOSTON -- Kevin Youkilis' locker in the Red Sox clubhouse was occupied Monday by the newest member of the team, utility man Brent Lillibridge.

Acquired from the White Sox on Sunday in the trade that sent Youkilis to Chicago, Lillibridge was trying to get his bearings straight Monday with his third organization since breaking into the big leagues with Atlanta in 2008.

"Kind of just have to turn the page pretty quick in this game, and excited to be part of this team," he said. "Obviously with a historic franchise and it's going to be a lot of fun."

Lillibridge, 28, was 11-for-63 (.175) in 49 games with Chicago this season. He split time at first base, third base, left field and center field.

"That's why I think I've been in the big leagues as long as I have, just being able to play the places I've been able to do, outfield, infield all that stuff," he said. "Hopefully that can help get me in the lineup here, too, but for the most part, I don't really have any expectations other than just being part of this team and helping us try to win and moving on past the White Sox."

Lillibridge is a career .237 hitter against left-handers. That statistic caught the eye of Red Sox manager Bobby Valentine.

"He looks like he could be a real contributing factor on a winning team," Valentine said. "He played well last year. And he's hit well against left-handers in his career, very well."

While most Red Sox fans might not have seen Lillibridge play, he turned heads last April 26 with a pair of game-saving catches in right field vs. the Yankees.

In the bottom of the ninth, Lillibridge made a leaping catch at the wall to rob Alex Rodriguez of a hit that could have driven in the tying run. He followed with a diving catch to end the game on line drive by Robinson Cano.

"I guess it ranks pretty well here with everyone who doesn't like the Yankees," Lillibridge said. "It's cool, it was a lot of fun. ... But got to make catches, make plays now that I'm here as a Red Sox. I look forward to it."

Lillibridge also has some family ties to New England. His father's side hails from Rhode Island.

"Growing up, my family were huge Red Sox fans, a lot of people from the New England area, Rhode Island, so my dad is pretty excited," he said.

Buchholz still ailing, but Beckett nears return

BOSTON -- Josh Beckett is progressing toward a return to Boston's rotation. The same does not hold true for Clay Buchholz.

Placed on the 15-day disabled list on Sunday with stomach illness, Buchholz remained hospitalized on Monday.

"Last night he was hoping to get out [Monday], but I was just in the training room, and it was decided to keep him a little longer," said manager Bobby Valentine. "Not because anything got worse, but they wanted to make sure it was as stable as possible before he gets out."

The right-hander is suffering from internal bleeding, but the Red Sox have not determined the exact source of the problem.

"I don't think so, no," Valentine said. "I'm concerned, but it's a personal matter with Clay. I bet you he feels OK. He sounded it last night."

Aaron Cook started in Buchholz's place on Sunday vs. the Braves, allowing three runs in five innings to win his first game with Boston.

Beckett, on the 15-day DL with right shoulder inflammation, threw a bullpen session prior to Monday's series opener vs. the Blue Jays. Still, the Red Sox won't place a timetable on his return.

"He said his shoulder felt great," Valentine said. "Because we have him on this disabled list, we're not going to let the calendar dictate. We're going to make sure he's really feeling good. So we'll wait before we make that determination, see how he feels tomorrow."

Beckett did not make himself available to the media on Monday.

He is eligible to return from the DL on Wednesday vs. Toronto, a game Jon Lester is scheduled to start.

Could Beckett start Thursday's game, when Boston begins a seven-game road trip with a four-game series at Seattle?

"I don't think it would be Thursday," Valentine said. "And that, again, is only because of the trip out there [to Seattle]. Why have that as another compounding situation that we have to deal with? Maybe the next day, if everything is going well, but we'll see. He's planning on pitching sometime soon."

Former reliever Franklin Morales has made two starts in Beckett's place, going 1-0 with 17 strikeouts in 11 innings.

Beckett is 4-7 with a 4.14 ERA in 12 starts this season. His last outing was June 11 at Miami, when he allowed four runs over seven innings in a loss.
