The Orioles optioned Garcia to Triple-A Norfolk on Monday.
Garcia covered two innings and threw 41 pitches in Sunday's 6-0 loss to the Yankees, so he was unlikely to be available out of the bullpen for the next day or two. The Orioles opted to swap Garcia off the 26-man active roster for a fresh relief arm in lefty Nick Vespi, who was called up from Norfolk in a corresponding move.
