Baltimore second baseman Brian Roberts played his first game since sustaining a concussion more than a year ago, going three inning for AA Bowie on Wednesday night.
Roberts walked in both of his plate appearances against Richmond. He scored standing up from first base on a double. He also fielded one grounder.
The 34-year-old Roberts had not been in a game since he had his second concussion on May 16, 2011, in Boston.
Roberts is a two-time AL All-Star. He is set to play for Orioles' minor league affiliates during his rehabilitation assignment, which can last up to 20 days.
