And a record 21 defences of the WBC Strawweight Championship... An immensely gutsy undefeated streak by anyone's standards. Uruguayan Lopez took on all comers and even stepped up to Flyweight during his career, becoming the widely recognised number one for many years. Ricardo was also a constant on the Pound for Pound rankings between 1993-2001. Lopez reached 47-0 before his flawless record came to an end with a draw against Rosendo Alvarez, a man who had four defeats to his name by the time his career came to an end.
