10 RUBEN OLIVARES 61-0-1, Mexico City, Mexico

THE Mexican had his first pro fight in 1965 at the age of 18, and scored 24 inside-schedule wins in a row. He cut a swathe through the ranks of the bantamweight division until he lost his WBA and WBC titles to Chucho Castillo in 1970.

During that run, Olivares not only beat the best, he destroyed them as he recorded 57 victories inside the distance. The draw came when he fought German Bastidas with an injured arm and was only able to use his left, and he knocked out that opponent in a return match. Top names such as Salvatore Burruni, Joe Medel, Lionel Rose and Alan Rudkin all fell early at the hands of the destructive Mexico City man.
