Brett Gardner suffers setback

NEW YORK -- Yankees left fielder Brett Gardner suffered a setback after playing in a rehab game Wednesday night in Rochester, and has been shut down by the team again after an MRI on Thursday.

Gardner has been on the disabled list since April 18 because of a bruised right elbow and a strained arm muscle.

"It's the muscle that he strained, that healed, that he's re-strained basically," Yankees manager Joe Girardi said. "He will not pick up a bat for 10 days, and then we'll go from there."

"I don't necessarily think this is a three-month thing," Girardi added. "But, unfortunately, I think we're gonna be without him for another 15 to 25 days."

Gardner, 28, was off to a good start this season for the Yankees. He was hitting .321 with a .424 on-base percentage in nine games. Last season, in 159 games, Gardner hit .259 with seven home runs, 36 RBIs and an American League-best 49 stolen bases.

"We miss him. There's no doubt about it," Girardi said. "The way he was swinging the bat, his defense, the way he puts pressure on defenses -- we miss his presence in left field. But we have to find a way to get it done without him."

Gardner suffered the injury while making a sliding catch in a game against the Minnesota Twins.

"It's not something structural, it's a muscle, we know that will heal," Girardi said. "But it's frustrating."
