Boyd was optioned back to Triple-A Toledo on Saturday.
Boyd was brought up as the 26th man to start the first game of Saturday's doubleheader against the Royals, but will head back to Toledo following a rough afternoon. The young southpaw gave up four runs on seven hits over just 3.2 innings, raising his ERA to 5.69 on the season. Regardless, look for Boyd to be a top option if the Tigers need an extra arm down the road.
