WBA junior flyweight champion Giovanni Segura (25-1-1, 21KOs) of Mexico added the WBO title to his waist by knocking out previously undefeated Ivan Calderon (34-1-1, 6KOs) of Puerto Rico in the eight round at the Coliseo Mario 'Quijote' Morales in Guaynabo, Puerto Rico. Segura's power eventually slowed down the faster man and broke him down. He finally put Calderon down with a shot to the body in the eight round. Calderon took the full count.
