The Baltimore Orioles have designated former All-Star Chris Tillman for assignment, offering the veteran right-hander a chance to remain in the organization and pitch at Triple-A. Tillman, who started the 2016 AL Wild Card game for Baltimore, is 1-5 with a 10.46 ERA in seven starts and hasn't pitched since May 10 because of a back injury. The Orioles cut Tillman at the conclusion of his 30-day minor league rehab assignment, opening a 40-man roster spot that allowed Baltimore to select infielder Renato Nunez from Triple-A. Nunez was in the lineup at third base for Friday's game at Toronto, Baltimore's first since trading Manny Machado to the Los Angeles Dodgers.
