His results were: Molina won the Boxing World Cup in Seoul, South Korea, November 1985, by knocking out Kelcie Banks in the finals.

Upon returning to Puerto Rico, the 20-year-old youngster announced to Rafael Bracero on TV he would be ready to fight professional world Featherweight champion Victor Luvi Callejas within a year.

Molina became a world champion by beating Laporte by a 12-round unanimous decision at Roberto Clemente Coliseum in San Juan.

On January 28, 1990, he avenged his loss to Suarez by knocking him out in the sixth round to retain the belt, but then, on May 20 of that year, he and Lopez met for their rubber match, this time in Reno.

He knocked Gunguzula out in the fourth round to become world champion once again, and, days later, he was the object of a large welcoming at Luis Muñoz Marín International Airport in San Juan.

Molina then moved up in weight to challenge the WBO lightweight champion Oscar De La Hoya, losing by a unanimous decision in 12 rounds in an HBO Boxing televised event.

Molina wasn't done with boxing, and he went on to win seven more fights in a row, including two decision wins, one of which was televised by the USA Network over Emanuel Burton, and another one over future Kostya Tszyu world title challenger Ben Tackie, which was on the undercard of the Lennox Lewis vs. David Tua fight's pay per view program.
