The Marlins optioned Maldonado to Triple-A Jacksonville on Saturday.
Maldonado appeared in three games for the Marlins after being recalled from Triple-A on Tuesday, but he'll now be sent back to the minors after surrendering three runs in one inning during Friday's blowout loss to the Phillies. Despite his 6.75 ERA through 16 MLB innings, there's still a chance the 26-year-old righty returns as bullpen depth down the stretch.
