Tillman (shoulder) will be placed on the 15-day DL on Wednesday, MASN Sports reports.

EDGE Analysis

His shot at 20 wins now seems out the window after Tillman developed some shoulder inflammation after his last start, which may necessitate a cortisone shot and subsequent shutdown period. Regardless of whether or not that treatment is necessary, Tillman is going on the DL and will not be eligible to return until Sept. 5, meaning the Orioles will have to turn back to Ubaldo Jimenez to fill a rotation spot for the time being.
