1971-10-25 Ruben Olivares w rsc 14 (15) Katsotoshi Kanazawa, Aichi Prefectural Gym, Nagoya, Japan - WORLD. Referee: Jay Edson. A punishing fight saw Olivares (117¾) retain his title when he put Kanazawa (118) down three times in the 14th round to win on the three-knockdowns in a round ruling, the final knockdown coming at 2.00 of the session. Prior to that, both men had given as good as they got in a fight that tipped first one way and then the other as each strove for an early finish. Unfortunately for Kanazawa, who several times seemed to be on the verge of a kayo win, his tremendous exertions weakened him and ultimately paved the way for his downfall.
