The Orioles optioned Reed to Triple-A Norfolk on Wednesday.
With Baltimore needing relievers to cover 12.2 innings over the first two games of its series in Boston, the club will bring aboard a pair of fresh arms for the bullpen in Keegan Akin and Beau Sulser while sending out Reed and Joey Krehbiel. Reed failed to retire a batter in Tuesday's 13-9 loss while getting charged with four runs (two earned) on two hits and a hit batsman.
