Baltimore Orioles Brian Roberts, who hasn't played a Major League game in more than a year because of concussion symptoms, could return to the Orioles on Tuesday, MLB.com reported. Roberts is scheduled to play the last game of his 20-day rehab period on Monday, and if things go according to plan, he will be activated from the 60-day disabled list and available to play for the Orioles on Tuesday. Manager Buck Showalter did not say when or how Roberts might be used. "I don't know, we'll see," Showalter told MLB.com. "As far as where he's playing and what position he's hitting and all that stuff, I haven't made that lineup out yet." In 13 Minor League games with several teams, Roberts has hit .263 with a home run and four RBIs. It's unclear what Roberts' return will mean for Robert Andino, who has filled in for Roberts at second base.
