The Orioles, who have surprised many this season, staying a top the standings in the American League East, are expected to activate second baseman Brian Roberts from the 60-day disabled list in time for the game Tuesday.

Roberts, who last played in the majors on May 16, 2011, due to concussion-like symptoms, has a career slash line of .281/.353/.416, and will likely be inserted back in the leadoff position in the lineup. The Orioles second baseman in his absence, Robert Andino, will be the odd man out in Roberts return, but will stay on the bench, and may even see more time at third base for Mark Reynolds, who has struggled.

Roberts, a two-time All-Star, posted a career best line of .314/.387/.515 in the 2005 season with 18 home runs and a 6.7 fWAR.
