Roberts played three consecutive rehab games at second base and took Saturday off. He will play again for Double-A Bowie on Sunday and Monday, with the plan to increase from two to three plate appearances. Roberts will head to the O's affiliate in Delmarva and play Tuesday and Wednesday, when the Baysox hit the road.
O's manager Buck Showalter said the plan is for Roberts to get four at-bats for the Shorebirds.
"The way he's got it drawn it up, he'd have the equivalent of Spring Training under his belt at-bats-wise, be in the mid-50s plate appearances [at the end of his rehab]," Showalter said. "So he's doing probably more work before the game, playing two or three innings."
Showalter, who was on hand for one of Roberts' games, said the other reports have been good and the biggest challenge for the veteran infielder is adjusting back to game speed.
Asked if he had discussed headfirst sliding with Roberts, a facet of his game that Roberts has admitted he may have to adjust, Showalter said: "We haven't gotten there yet. [I'll] kind of believe that when I see it. I think he's going to play the game with some energy. That's one thing, the couple games I saw his clock isn't quite there ... he'll get there."
