1977-07-30 Carlos Monzon w pts 15 Rodrigo Valdez, Louis 11 Stadium, Monte Carlo, Monaco - WORLD. Referee: Roland Dakin. Scorecards: 144-141, 147-144, 145-143. The return between the pair was almost as exciting and as close as their previous go and the champion was always wary of Valdez’s power. Monzon (159), who was pushed hard all the way, had been dropped by a whistling right to the jaw in the second round for what he claimed was the first time he had been decked since 1963, but he had gradually gained control as the contest wore on. Indeed, in the tenth it looked as though Valdez (158) might be stopped with blood pouring from his left eye and swellings around both eyes. It was Monzon’s countering that ultimately gained him the initiative and although Valdez fought like a man possessed in the last three sessions he failed to make up the leeway.
Monzon retired as undefeated champion in August when the WBC forced him to vacate their portion of the title after he failed to agree terms for a championship contest against Valdez. With the WBA supporting Bennie Briscoe and the WBC backing Valdez, neither body saw the need for an eliminator.
