According to Brittany Ghiroli of MLB.com, right-hander Alfredo Aceves did not make the Orioles and will use the opt-out clause in his minor league contract in order to become a free agent.
Aceves allowed five runs on 11 hits and two walks over 10 innings this spring and struck out six batters. The 31-year-old was in the mix for a bullpen spot, but the Orioles appear likely go with right-hander Evan Meek, another non-roster invitee, assuming they don’t make another move before Opening Day.
Aceves had a 2.61 ERA in a swingman role with the Red Sox back in 2011, but he owns a 5.21 ERA in the majors since and has earned a reputation for attitude problems.
