After a weekend of fights, Zanfer Promotions is now interested in making a junior flyweight fight between Moises Fuentes (16-1, 8KOs) and WBA champion Roman  "Chocolatito" Gonzalez (33-0, 28KOs).

On Saturday night in Puerto Rico, Fuentes had the biggest win over his career with sensational defense of the WBO strawweight title. He knocked out veteran Ivan Calderon in five rounds. At Friday's weigh-in, Fuentes struggled to make weight. After four attempts on the scale, Fuentes finally made the weight. He later said it might be his final fight at 105-pounds.

Gonzalez made an easy non-title fight in Managua. He stopped Stiven Monterrosa in three rounds.

Zanfer promotes Fuentes and has a co-promotional agreement on Gonzalez.
