1980-04-03 Sam Serrano w rsc 13 (15) Battlehawk Kazama, Central Gym, Nara, Japan - WBA. Referee: Stan Christodoulou. Returning to the ring after almost a year out of action with hand injuries and a number of other problems, Serrano (129½) put his title on the line against the switch-hitting Kazama (129¾). Although there had been no knockdowns, Serrano, way out in front by dint of his clever boxing, finally caught up with the fading Kazama in the 13th with a left hook that sent the Japanese champion staggering against the ropes. With the exhausted Kazama covering up unsuccessfully from a battery of lefts and rights the referee brought the fight to an end with just 45 seconds having elapsed.
