The Miami Marlins have fired John DeCicco, the man who has appeared as Billy the Marlin at home games for more than a decade.

The club said Billy the Marlin will remain the team's mascot but with a different person in the costume. Team officials didn't give a reason for the firing.

The Marlins have fired a number of executives and traded some of the team's best players since a new ownership group led by CEO Derek Jeter took over last fall.
