BALTIMORE — Brian Roberts' frustrating season is over.
The Orioles second baseman will have season-ending surgery to repair a torn labrum in his right hip. Roberts made the announcement Sunday, less than 24 hours after he began a rehab assignment with Class A Aberdeen.
"It just hasn't responded the way we were hoping it would," he said. "Deep down in my gut, I think I knew before last night."
Roberts went on the disabled list July 3. The first doctor he spoke to recommended surgery, but a second suggested rehabilitation. Robert received a cortisone shot and worked out at the team's facility in Florida before heading to Aberdeen.
After going 0-for-4 with a walk on Saturday night, he abandoned the plan.
"We kind of knew this was a possibility going in," Roberts said. "We wanted to give it the best possible shot we could to get back out there and try and help for the last two months of the season, but it's not going to put me in a position to play the way that I think is going to be necessary to help."
Roberts, 34, missed the start of the season with a concussion. He returned June 12 and got three hits against the Pirates but was batting .182 in 17 games before going on the disabled list. Last season, he played in just 39 games because of a concussion. And he played in 59 in 2010 because of back and abdominal injuries.
In other Orioles news, LF Lew Ford's contract was purchased from Triple-A Norfolk, and he went 0-for-3 with a walk and an outfield assist in his first big-league game since 2007.
