Orioles right-hander Darren O’Day was placed on the 10-day disabled list Wednesday with a hyperextended right elbow.
O’Day last pitched on Friday in Oakland, where he threw a season-high 31 pitches and allowed a run on two hits, all with two outs, in 1 2/3 innings. That was the first earned run he’d allowed not via a home run this season, and in 14 1/3 innings over 13 appearances had a 3.77 ERA with 18 strikeouts against two walks.
Because disabled list trips can only be backdated three days, O’Day’s move there was backdated to May 6, meaning he can be activated in a week.
