The Marlins have called up pitcher Nick Masset from Triple-A and optioned pitcher Jose Urena back to the minors, the team announced Tuesday.
Urena was called up last week when David Phelps was placed on paternity leave. He worked three innings in two appearances, allowing three runs on four hits. Masset threw 45 innings in 2014 for the Rockies, posting a 5.80 ERA in 51 appearances.
The team has also designated Matt Tracy for assignment. Tracy made one appearance, allowing three runs on two hits for the Marlins.
