Carlos Ortiz stopped Sugar Ramos in four rounds to retain the World Lightweight Title. It was a rematch of their October 1966 bout, won by Ortiz via Round 5 TKO.

Ortiz was the great lightweight champion of the 1960s and one of the best boxers ever from Puerto Rico. His first world title came in 1959, when he captured the newly resurrected light welterweight title by beating Kenny Lane. Ortiz defended that belt twice, handing the Italian great Duilio Loi his second loss in June 1960, before dropping the belt to Loi in a rematch three months later. Loi won the 1961 rematch.
