Yokohama International Swimming Pool, Yokohama, Japan - Defending his world title for the first time, WBC flyweight champion Roman “Chocolatito” Gonzalez (41-0, 35 KOs) retained his crown with a sixth round stoppage of Rocky Fuentes (35-7-2, 20 KOs), who couldn't recover from the hard punching assault after going down.

Gonzalez captured the title, which was his third divisional belt, in September with a ninth round TKO of Akira Yaegashi in Tokyo.

WBC super featherweight champion Takashi Miura (28-2-2, 21 KOs) dropped Mexico's Edgar Puerta (23-5-1, 19 KOs) in the first round, controlled the fight and eventually closed the gusty challenger out in the sixth.
