McCaughan is scheduled to start Saturday's game against the Phillies in Miami.
The 28-year-old righty will make his second straight turn through the rotation after he took a no-decision while giving up four runs (three earned) over four innings versus the Giants last Sunday. Over six total appearances in the big leagues this season between the Marlins and Guardians, McCaughan owns an 8.24 ERA, 1.98 WHIP and 10:10 K:BB across 19.2 innings.
