MIAMI, Florida (Reuters) - The slumping Florida Marlins fired hitting coach John Mallee on Wednesday and handed Eduardo Perez the task of revitalizing their sputtering offense.

The Marlins (31-29) were in dire need of a shakeup after losing seven in a row and languishing in most of the key offensive categories.

"It's been very frustrating," Marlins President of Baseball Operations Larry Beinfest told the team's website (

"I know the guys are frustrated. We're frustrated. We need to find a way to execute and score runs when we have that opportunity."

Mallee, who was given the job last June year, was shown the door with Florida hitting just .248 with a .321 on-base percentage.

Perez, 41, enjoyed a 13-year career that included time with six different teams. He is the son of baseball Hall of Famer Tony Perez, and was most recently working as a television analyst.
