1973-09-08 Roberto Duran w rsc 10 (15) Guts Ishimatsu, New City Gym, Panama City, Panama - WBA. Referee: Nicasio Drake. Dominating the fight throughout, this time round the champion showed improved skills, but it never stopped his remorseless forward march as he battered Ishimatsu (135) two-fistedly for most of the rounds. While there was only going to be one winner, Ishimatsu did not come to lie down and in the third he cut Duran (133½) badly over the left eye, an injury that forced the latter to up the tempo even more. By the eighth, Ishimatsu, who was cut over the left eye, was beginning to give way under relentless pressure and he was dropped twice in the ninth and three times in the tenth before the referee called it off to rescue him with 50 seconds of the session remaining.
