1979-02-18 Sam Serrano w pts 15 Julio Valdez, Hiram Bithorn Stadium, San Juan, Puerto Rico - WBA. Referee: Larry Rozadilla. Scorecards: 155-135, 146-138, 147-143. With Valdez (130) on the floor for an automatic ‘eight’ count in the first round after a left hook had done the damage, it looked to be an early night for the champion. However, Valdez regrouped, but unable to get to Serrano (129½) he started to resort to foul tactics, which were reciprocated. Again Serrano had Valdez in trouble after a right to the head in the eighth, but he failed to follow up and had to be content with the lop-sided verdict in his favour. Unfortunately, there was more action following the fight when chairs flew after Serrano had been hit with a right cross from one of Valdez’ seconds.
