Tillman is dealing with shoulder discomfort and his next start has been pushed to Saturday against the Astros, MLB.com's Brittany Ghiroli reports.

EDGE Analysis

He was scheduled to start Wednesday against the Red Sox, but instead the Orioles will take advantage of Monday's off day to move everyone else up a day, allowing Tillman to have a few days to try to get his shoulder right. The schedule tweak doesn't guarantee he will be able to take the mound Saturday, especially given the nature of the ailment. Dylan Bundy will start Wednesday's game with Kevin Gausman and Wade Miley starting Thursday and Friday, respectively.
