Tillman (shoulder) is likely headed to the DL, MASN's Roch Kubatko reports.

EDGE Analysis

He may receive a cortisone shot in the shoulder, as he is dealing with the same discomfort he had prior to starting Saturday and then leaving after he was ineffective over two innings. The move will be backdated to Aug. 20, so Tillman would be able to come off the DL on Sept. 5 to start at Tampa Bay if the 15 days of rest proves to be a satisfactory remedy for his shoulder soreness. The Orioles don't have a quality option to step into the fifth spot in the rotation, and Ubaldo Jimenez might get the first crack in Washington on Thursday.
