Brian Roberts (concussion) is slated to play second base and bat leadoff in his return from the disabled list Tuesday. The Orioles have held off on making an official roster move, likely due to some of the inclement weather in the Baltimore area. However, if everything goes as planned, the 34-year-old will appear in a major league game for the first time since May 16, 2011. If he can stay on the field and avoid any setbacks with concussion symptoms, he should have value in most mixed leagues.
