Gómez won the gold medal at the 1974 Central American and Caribbean Games held in Santo Domingo, Dominican Republic, and 1974 World Championships in Havana, Cuba before turning professional. He also competed in the 1972 Olympic Games in Munich, Germany, getting eliminated by an Egyptian rival in the Olympic's first round of bouts. He compiled an overall record of 96 wins and 3 defeats as an amateur boxer. Because of his family's economic situation, he decided not to wait for the 1976 Olympic Games in Montreal, Quebec, Canada, opting to begin making money right after the 1974 World Amateur Boxing championship instead. Coming from Puerto Rico, he settled for less money and exposure from the American media, and moved to Costa Rica, where he began to tour all of Central America in hopes of finding matches. His professional debut came in Panama City, Panama, where he fought to a draw with Jacinto Fuentes.
