Chris Tillman on DL with ab strain
The move announced Thursday is retroactive to March 22, which allows Tillman to pitch in the Orioles' fifth game of the season on April 6 against Minnesota.
Tillman was scratched from his scheduled March 10 start because of abdominal soreness and has pitched only in minor league games.
Baltimore also reassigned outfielder Trayvon Robinson to its minor league camp.
