At 21, he won the WBC featherweight title and went on to successfully defend the title 10 times in a two-year period. Sadly, less than a month after his final bout he was killed in a car accident while driving in Santiago de Querétaro, Mexico. He was inducted into the International Boxing Hall of Fame in 1991.
