The fight's result proved controversial, Puerto Ricans and other boxing fans who saw the fight have argued about the scoring ever since. Minutes later, Camacho was announced as winner and still WBC world Lightweight champion by a split decision (scores of 118–111 and 115–114 for Camacho, and 114–113 for Rosario). Rosario continued landing in round twelve, also sweeping the round on all judges' cards. Feeling he had a lead on the scorecards, Camacho again circled around the ring and grabbed, to avoid Rosario's punches. In round eleven, Rosario hurt Camacho again, with a sneaky left hook through Camacho's guard. Rounds six to ten were dominated by Camacho (out of a possible fifteen combined rounds, as three judges were scoring the fight, Rosario was given only one round between rounds six and ten by one judge). On the verge of falling, Camacho took his distance for the rest of the round, and Rosario continued on pursue, landing other damaging blows. In round five, Rosario connected with a left to the chin as Camacho was getting ready to fire a right hand, and Camacho's knees buckled. In the fourth, Rosario began to turn things around by landing an uppercut in the final seconds, which earned him the round.

The first three rounds were swept by Camacho on all three judges' scorecards by keeping Rosario away with his jab and outcircling the pursuing challenger. This was seen by many as an unpatriotic act, although Camacho had always proclaimed to be proud of being a Puerto Rican, and has continued to proclaim so. Camacho was criticized by many Puerto Ricans because of the trunks he wore that day he wore a Puerto Rican flag, but with the flag's white star to his back. Lightweight title with a seventh round knockout of Refugio Rojas. The undercard included a young Mike Tyson knocking out Reggie Gross in the first round and Julio César Chávez (who would later beat Camacho, Ramirez and Rosario) defending his WBC world Jr. The fight was for the WBC World Lightweight Title, earned by Camacho after his win over José Luis Ramírez, who had, in turn, beaten Rosario for the title. Sports reporter Rafael Bracero travelled to New York to make a documentary about the fighters and the fight, and even former BSN basketball star Fufi Santori, a self-declared not fan of boxing, got caught in the fight's hype, making a prediction on television on the day of the fight.

Televised in the United States by HBO Boxing and in Puerto Rico by WAPA-TV (and to several other countries), the fight garnered wide media attention, especially in Puerto Rico: It was the fourth time that two Puerto Ricans battled for a world boxing title, and, at that time, it was also the world title fight that pitted the two boxers who hailed from the closest birth-places in boxing history (Camacho was born in Bayamón, while Rosario was from Toa Alta, a mere fifteen-minute car drive away from Bayamón).
