Ellington was optioned to Triple-A New Orleans on Friday, Joe Frisaro of MLB.com reports.
Although Ellington was extremely effective during his 10-game stint with the Marlins, notching a .79 ERA to go with a 1.15 ERA, the Marlins needed to clear a spot on the roster for Friday's starter, Justin Nicolino. Ellington's strong showing with the big league club ought to earn him a call back up to the Marlins before too long, but for now, he'll work out of the bullpen at Triple-A.
