In Mexico, Ultiminio "Sugar" Ramos built his historical career. On 21 March 1963, Ramos had a bout scheduled at
Dodger Stadium. On that day, Ramos severely beat
Davey Moore. In the 10th round, Moore was knocked out. Four days later, Moore died from injuries sustained to his brain stem. This was similar to Ramos' twelfth professional fight in which José Blanco died from injuries sustained in the fight. Ramos would defend his title three times including against Ghanaian challenger
Floyd Robertson, via a controversial split decision victory. Ramos lost his titles in 1964 to
Vicente Saldivar after the fight was stopped in the twelfth round due to cuts. Ramos then moved up to lightweight, eventually earning a shot at then champion
Carlos Ortiz in 1966. Ramos would lose the fight via fifth-round TKO, and then an immediate rematch by TKO in the fourth round. He continued boxing until 1972. ==Professional boxing record==
