He debuted as a professional 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), after which he was able to make his San Juan debut against Benny Paret, a future world welterweight champion from Cuba. Torres and Paret fought to a ten-round draw, and 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.
