The Orioles placed O'Neill on the 10-day injured list Friday, retroactive to Aug. 6, due to right wrist inflammation, Roch Kubatko of MASNSports.com reports.
O'Neill jammed his wrist against the outfield wall Tuesday, and while his X-rays returned negative, the Orioles will give him an extended period of rest. Jordyn Adams was recalled from Triple-A Norfolk as part of a series of moves Friday. Look for Adams, Jeremiah Jackson and Greg Allen to see most of the work in right field while O'Neill is idle.
