1973-04-19 Koichi Wajima w pts 15 Ryu Sorimachi, Prefectural Gym, Osaka, Japan - WBA/WBC. Referee: Nobumitsu Inukai. Scorecards: 72-71, 72-71, 71-71. Crowding Sorimachi (151¼) from the start the aggressive champion, deciding as always that attack was the best form of defence, hammered away at his fellow countryman who was only too happy to fire back. With both men being known punchers the exchanges had the fans on the edge of their seats in anticipation, but it was the strength of Wajima (154) that eventually won the day by a slight margin. Although Sorimachi ripped through Wajima’s defences at times, especially with right crosses, it was the latter who finished the fresher.
