Junto Nakatani TKO4 Angel Acosta... It was shaping up as an action fight, but a Junto Nakatani left hand shattered Angel Acosta's nose in the bout's opening stages, and that spelled the beginning of the end for Acosta. Nakatani retained his WBO flyweight world title with a fourth-round stoppage after referee Rocky Burke and the ringside physicians halted the fight due to the damage Acosta sustained. Nakatani (22-0, 17 KOs), from Japan, won the vacant title last year and made a splash in his United States debut. Acosta (22-3, 21 KOs), from Puerto Rico, previously held a world title at light flyweight and saw his two-bout winning streak come to an end. Nakatani said, “I caught him in the first round right in the nose and I was able to use my pace to fight him, so that worked out really well. I knew (I had broken his nose). I thought it was a good win. I want to unify the titles.”
