OAKLAND -- A May return seems unlikely for utility player Adam Rosales, who confirmed on Sunday afternoon that he still hasn't been cleared for full baseball activities and likely won't be for at least another four weeks.

That's when Rosales is next scheduled to see his doctor, who told the infielder last week that his right foot has recovered 90 percent. Rosales was hoping he'd be at 100 percent by then, but bones around his surgically-repaired navicular bone are still gaining strength.

"It's frustrating," Rosales said, "because I really want to be out there."

The 27-year-old underwent surgery on Dec. 8, and he was initially expecting to face a recovery time of three-to-four months. Now, June seems the likely goal.

Before the onset of his injury, which initially crept up in August, Rosales was batting .271 with seven home runs and 31 RBIs in 80 games, and was the first A's player since 1995 to start at least one game at six positions.

In his stead, Andy LaRoche has fulfilled the utility role, making starts in 10 games at four different positions, including four at third base, where manager Bob Geren noted he wants to give LaRoche an "extended look" while regular Kevin Kouzmanoff continues to find an offensive and defensive groove.

Braden not optimistic about making next start

OAKLAND -- A's lefty Dallas Braden, who exited Saturday's outing after five frames because of shoulder stiffness, was scheduled to see the team orthopedist on Sunday to determine the severity of his injury and whether he'll be able to make his next start.

Following Sunday's game, an A's official said the results of Braden's visit with the doctor were unavailable.

Braden, uncharacteristically sporting a rather glum face on Sunday morning, did not appear optimistic about being ready for that start, which is slated for Friday in Seattle. He was a man of few words, simply saying his shoulder feels "tight and it hurts."

A's manager Bob Geren acknowledged Braden's gloomy nature but relayed a sense of understanding.

"He didn't look happy last night," Geren said. "Anytime he's pitching as well as he is and has to come out of the game, there's no way I'd expect him to be anything but disappointed. He's such a competitor."

Before exiting Saturday's contest against Detroit, Braden had allowed just three hits and one unearned run with five strikeouts and two walks. Carrying a 3-1 lead, he was replaced by Brad Ziegler to start the sixth in an eventual 6-2 victory.

"If there was any way he could have continued," Geren said, "he would have."

The A's have an off-day Monday, meaning Braden would be given an extra day of rest if cleared for Friday's outing. Geren noted that day could be "beneficial to us" and did not speculate who would start in Braden's place if he's unable to go.

Right-hander Tyson Ross and lefty Bobby Cramer, currently stationed as long-relief options in the bullpen, represent likely candidates.

The 27-year-old Braden, who said he has never experienced shoulder problems in his big league career, has been on the disabled list twice in four previous seasons. He is 1-1 with a 3.00 ERA in three starts this year.

Wuertz to make rehab appearance on Monday

OAKLAND -- Righty Michael Wuertz, rehabbing from a strained left hamstring, is scheduled to make his second Minor League rehab appearance with Class A Stockton on Monday, manager Bob Geren said. The reliever is slated to again throw one inning on Monday, but there is no timetable on his return.

"He needs to get sharp," Geren said. "When he's sharp and ready to help us, he'll be back."

Wuertz, coming off a 2010 campaign in which he posted a 4.31 ERA and 1.41 WHIP, had appeared in just one game this season before suffering the injury. He tossed one shutout inning with two strikeouts against the Mariners on Opening Night.

Worth noting

Andrew Bailey (forearm) threw a bullpen on Sunday and said all went well. The right-handed reliever continues to make progress toward a Minor League rehab stint, but there is still no timetable for his return. ... Ryan Sweeney experienced hamstring tightness after tripling in Saturday night's contest, but was available to pinch-hit on Sunday, Geren said.
