The Marlins optioned Bermudez to Triple-A Jacksonville on Wednesday, Christina De Nicola of MLB.com reports.
Miami selected the left-hander's contract from Jacksonville over the weekend, and he'll return to Triple-A after giving up two runs over 3.2 frames of long relief during Tuesday's contest. Bermudez had a 6.46 ERA over 23.2 innings for Jacksonville this season, and he's unlikely to see anything more than low-leverage opportunities down the stretch for the Marlins, if he even rejoins the MLB roster.
