Kazuto Ioka delivered a master class in his successful WBO super flyweight title defense on Tuesday, while compatriot Kosei Tanaka retained his WBO flyweight title by knockout.
Ioka made light of Jeyvier Cintron's 12-cm reach advantage to move in and batter his opponent's body from point-blank range in a unanimous decision at Tokyo's Ota City General Gymnasium.
The 24-year-old Cintron had the best of the early rounds, but eventually had no answer for the wily 30-year-old Ioka, who came determined to teach the youngster a lesson.
