The Marlins announced today that they have designated infielder Deven Marrero for assignment. His roster spot will go to fellow infielder Neil Walker, who was activated from the injured list.
Marrero, who is closing in on his 29th birthday, was brought up recently to fill out the Miami roster. He has seen action in parts of five MLB campaigns but has never shown the spark with the bat that was anticipated when he was chosen in the first round of the 2012 draft.
