"I'm not exactly sure how to describe it," president of baseball operations Andy MacPhail said of Davis' shoulder, which an MRI revealed to have a partial tear. "I don't think it's a 911 situation, but it's something we have to watch and make sure it doesn't get worse."
Davis will see noted orthopedic surgeon Lewis Yocum in Los Angeles on Friday, and while MacPhail was hesitant to comment on the length of Davis' DL stint, given the nature of his injury, surgery appears to be a distinct possibility. The Orioles already lost outfielder Luke Scott for the season after he underwent shoulder surgery, and Yocum removed a bone spur on pitcher Jake Arrieta's right elbow -- ending his season -- on Friday.
"I don't know about shutting it down, I don't really want to use that word," Davis said. "But I do know what I need right now is extended rest."
Acquired in a Trade Deadline deal -- along with pitcher Tommy Hunter -- from Texas, Davis said he never got treatment on the area until recently. He thinks the upped playing time for the Orioles -- where he's been the everyday first baseman -- may have aggravated a preexisting injury.
"It is hard to do [rest the injury] having just been traded over here. I want to show what I can do, what I'm capable of doing, but at the same time I don't want to play at 75 percent," said Davis. "I want to go out there and be able to hit and throw."
The 25-year-old Davis hit .241 with four homers and nine RBIs in 38 Major League games split between Texas and Baltimore, and he collected his third multihit game as an Oriole on Saturday against Detroit.
The roster move, which is retroactive to Monday, clears a roster spot for lefty Brian Matusz, who was officially recalled from Triple-A Norfolk to start Tuesday's game in Oakland.
