Brian Roberts knew going into his minor league rehab assignment with short-season Class-A Aberdeen that it might be the last few innings of baseball he would play this season.

A second opinion on the torn labrum in his right hip gave the second baseman optimism that he might be able to return to help the Orioles for the stretch run. An initial review suggested surgery. Roberts wanted to test his own limits, and in his first game with Aberdeen on Saturday, he played the entire game.
