The Marlins optioned Brzykcy to Triple-A Jacksonville on Thursday.
Brzykcy made just one appearance after being called up from Triple-A on June 30, giving up one earned run on one hit and two walks while fanning two batters across two innings. He'll now head back to Jacksonville to help make room on the active roster for Janson Junk (shin), who returned from the injured list Thursday, and Ryan Gusto, who was recalled from Triple-A.
