The move was expected once Davis’ injury was made public. The Orioles optioned left-hander T.J. McFarland after Friday night’s game to create a roster spot.
Weeks, 27, was acquired by the Orioles in December in the trade that sent closer Jim Johnson to the Oakland Athletics. Weeks was one of the last cuts in spring training and then batted .296 with a .451 on-base percentage in 17 games at Triple-A Norfolk.
Weeks’ presence will allow the Orioles to shift Ryan Flaherty to first base until the club decides whether it needs to place Davis on the disabled list. Weeks could play second along with Jonathan Schoop and Steve Lombardozzi; that duo can also play third base until Manny Machado comes off the DL.
Davis, the reigning MLB leader in homers and RBIs, was pulled from Friday’s game in the fifth inning after feeling discomfort in his oblique. The Orioles have no obvious replacement at first base for Davis if he needs an extended DL stay.
