Ryan Flaherty, who was slated to be the designated hitter, will start in Hardy’s place and bat eighth. Steve Pearce will be the designated hitter and bat seventh.
Hardy had previously started all but one game this season, and that day off was scheduled. He’s batting .254 with 22 home runs and 66 RBIs in 120 games this season.
Depending on Hardy’s availability, Alexi Casilla and Taylor Teagarden could be the lone bench options for the Orioles.
