Miles will serve as the Blue Jays' opening pitcher for Wednesday's game against the Royals, Mitch Bannon of The Athletic reports.
Miles has previously made four starts and has covered at least three innings out of the bullpen on seven other occasions, but he'll likely be in store for a lighter workload Wednesday. He hasn't recorded more than three outs in any of his last eight appearances and may not be stretched out enough to give the Blue Jays more than 2-to-3 innings. The Blue Jays will likely lean on a number of relievers to fill innings once Miles exits the game.
