1974-11-28 Guts Ishimatsu w co 12 (15) Rodolfo Gonzalez, Prefectural Gym, Osaka, Japan - WBC. Referee: Yusaku Yoshida. Trying to regain his former title, Gonzalez (133¼) was out to prove that his previous fight against Ishimatsu (135) was a fluke and came about because of weight-making difficulties. This time round, having begun aggressively he was getting to the champion before being cut over the left eye in the fifth round. Thereafter, he was careful to protect the optic from further damage, especially with the doctor continuing to check the injury out. Nevertheless, Gonzalez was well in the contest coming into the 12th before being staggered by a cracking right to the head and counted out at 2.23 of the session following another smashing right hand.
Rated at number two by The Ring magazine and two places above Ishimatsu, Ken Buchanan would be the latter’s next challenger. Since losing his WBA title to Roberto Duran, Buchanan had won 13 straight, beating Carlos Ortiz, Chang-Kil Lee, Frankie Otero (twice) and Joe Tetteh. He had also relinquished the British title after winning it from Jim Watt and was the reigning European champion. To win that title, Buchanan had defeated Antonio Puddu before defending his crown against the same man and Leonard Tavarez.
