Jaime Munguia W12 Nikita Zon.... Jaime Munguia retained his WBA super middleweight title in tougher than anticipated bout against Nikita Zon. After twelve rounds, judges sscored it 116-112 and 117-111 (twice), a unanimous decision in favor of Munguia. The champion, from Mexico, survived a nightmarish sixth round, but got it done in this harder-than-expected victory. Zon, who had Munguia on the ropes in that sixth, can only grow from here.
