Enright was returned Thursday to the Guardians, Daniel Alvarez-Montes of ElExtraBase.com reports.
Miami selected Enright away from Cleveland during the Rule 5 Draft back in December, but he was diagnosed with Hodgkin lymphoma soon after and the Marlins ultimately designated him for assignment this past Sunday following a nine-appearance rehab stint between their Double-A and Triple-A affiliates. The 26-year-old right-hander has yet to pitch in a major-league game.
