O'Neill is out of the lineup for Sunday's game against the Marlins.
O'Neill will take a seat while the Orioles deploy Jordan Westburg at designated hitter and roll out a starting outfield of Colton Cowser, Cedric Mullins and Ramon Laureano from left to right. Since returning from the 10-day injured list July 4, O'Neill has gone 3-for-22 (.136) with a solo home run, two walks and an additional run in six games.
