The Baltimore Orioles are placing Chris Tillman on the disabled list with right shoulder inflammation.

Tillman received a cortisone shot on Tuesday.

"I thought once it got loose it would really go away, but it never really did, and that was my first time actually experiencing it while throwing," Tillman said. "Last time, I was pretty sore right after my start, but after feeling it today, I'd much rather just get this behind us and get out in front of it so that way we're not worried about it for the rest of the year."

Ubaldo Jimenez will take Tillman's turn in the rotation on Thursday.
