After three years, Hermida was called up and made his MLB debut on August 31, 2005. At his first time at bat, he scored a grand slam, making him the second person in MLB history to accomplish that. He continued with the Marlins, playing in 23 games during the 2005 season.

During the 2006 season, he joined the Marlins for 99 games, missing time in April and May from a right hip flexor. After recovering and a short stay with the Marlins' affiliate for rehabilitation, he rejoined the Marlins' roster. He again joined the Marlins for the 2007 season, playing 123 games. He set career high numbers in 2007, with 127 hits, 54 runs and 18 homeruns.
