WASHINGTON -- Less than two weeks after making his Major League debut, Marlins reliever Arquimedes Caminero was sent back to the Minors following Wednesday night's 4-3 loss to the Nationals. Miami optioned the right-hander to Triple-A New Orleans and is expected to make a corresponding roster move on Thursday.
Caminero surrendered two hits in the sixth inning Wednesday night, including a game-tying solo home run by Jayson Werth. The 26-year-old reliever allowed as many hits in the game as he had in his first three Major League appearances combined, but his performance was not enough to warrant a spot in manager Mike Redmond's bullpen.
The move will still be a promotion of sorts for Caminero, who jumped straight to the Marlins from Double-A Jacksonville on Aug. 16. He was 5-2 with a 3.61 ERA in 42 appearances with the Suns this season.
Caminero could rejoin the Marlins soon, as rosters expand on Sunday.
