1980-08-02 Yasutsune Uehara w co 6 (15) Sam Serrano, Joe Louis Arena, Detroit, Michigan, USA - WBA. Referee: Luis Sulbaran. After 15 minutes of boxing all three officials had the champion in front, Uehara (129¼) having been subjected to left and right-hand counters and the occasional uppercut. All of his work had virtually been nullified up to that point, but in the sixth session things changed for Uehara when Serrano (130), pushed back against the ropes, failed to spot a huge overarm right which crashed against his jaw and sent him down on his haunches. Desperately trying to get to his feet, Serrano’s reign came to an end as he was counted out with just one second of the round remaining.
