The event, Thursday's $100-per-head Fish 'N Chips Casino Party, lured fans of the team by offering an open bar, various casino games and the chance to "rub elbows" with their favorite Marlins players, coaches and alumni.
When none of those parties showed up, however, fans were left with blackjack tables and Billy The Marlin.
The team said Thursday that players' attendance at the event was not mandatory, according to the report.
On Monday, the Marlins hired general manager Dan Jennings as the team's new manager in the wake of Mike Redmond's firing.
Fan reaction ranged from unsurprised to angry, according to the New Times.
Heading into Friday, Miami had a 16–26 record. It was the second-worst record in the National League.
