The Orioles placed right-handed reliever Darren O’Day on the 15-day disabled list Saturday with what the team called a right rotator cuff strain.
The move comes after O’Day flew back to Baltimore on Friday and was seen by team orthopedist Dr. Michael Jacobs. He complained of shoulder discomfort following a rocky outing on Thursday in Oakland.
The Orioles have recalled right-hander Tyler Wilson to fill O’Day’s roster spot in the bullpen. Wilson joined the club on Friday and was on the 24-hour taxi squad while the Orioles awaited word on O’Day.
O’Day had struggled in his recent outings, allowing five runs in his last three appearances.
