About two dozen protesters are outside Marlins Ballpark, expressing their displeasure with manager Ozzie Guillen.
The demonstration Thursday came before Miami's afternoon game with the Chicago Cubs. Many waved Cuban flags, held signs and used a megaphone to criticize the manager.
Guillen's comments lauding Fidel Castro in a Time magazine interview sparked anger within the Cuban community in South Florida.
Guillen has since apologized and served a five-game suspension issued by the Marlins. He returned to the dugout Tuesday against the Cubs. The Marlins have won the first two games of the series.
