PHOENIX -- To make room on the roster for Nathan Eovaldi, the Marlins optioned left-handed reliever Edgar Olmos to Double-A Jacksonville following the club's 3-2 victory over the D-backs on Monday night.
In his first Major League stint, Olmos made five appearances, tossing five innings and allowing nine runs (four earned) on seven hits. He also struck out a pair and walked three.
The 23-year-old's best outing came in his big league debut when he threw 1 1/3 scoreless innings against the Phillies in Philadelphia.
Eovaldi will make his season debut Tuesday when he takes the mound to start the second game of the Marlins' three-game set with the D-backs at Chase Field.
