He professionally debuted in 1958 with a first-round knockout of George Hamilton in New York. Twelve wins in a row followed, ten of them by knockout (including wins over contenders Ike Jenkins and
Al Andrews). Afterward, he made his
San Juan debut against
Benny Paret, a future world welterweight champion from Cuba, in which Torres and Paret fought to a ten-round draw. In 1960, Torres went back to campaigning in New York, where he scored three wins that year, all by decision, including two over Randy Sandy. In 1961, Torres made his hometown debut with a four-round knockout win in a rematch with Hamilton at Ponce. He had six more fights that year, winning all of them by knockout. Torres kept his knockout streak alive through 1962 with three more knockout wins but, in 1963, he suffered his first loss, being stopped in five by
Cuba's
Florentino Fernández, the only boxer ever to beat Torres by a knockout as a professional. After that setback, Torres went back to training and had one more fight that year. That time around, he was able to beat another top contender in
Don Fullmer,
Gene Fullmer's brother, with a ten-round decision win in
New Jersey. In 1964, Torres beat a group of name boxers, including
Jose Gonzalez, Walker Simmons (twice), Frankie Olivera,
Gomeo Brennan, and former world Middleweight champion
Carl ("Bobo") Olson, who was taken out in one round. After this, Torres was ranked number one among Light-Heavyweight challengers. His title shot arrived in 1965 at
Madison Square Garden. Torres defeated the
International Boxing Hall Of Fame member and World Light Heavyweight champion
Willie Pastrano. In doing so, Torres became the third Puerto Rican world boxing champion in history and the first Latin American to win the world Light Heavyweight title, knocking Pastrano out in round nine. Later that year, he fought a non-title bout versus
Tom McNeeley (father of former
Mike Tyson rival,
Peter McNeeley) in San Juan, winning a ten-round decision. After his second defeat to Tiger, Torres only fought twice more (against
Bob Dunlop in 1968 and
Charley "Devil" Green in 1969), retiring after 1969. ==An active retirement==
