Carmen Basilio

Carmen Basilio was an American professional boxer who was a two-time Undisputed Welterweight Champion and Undisputed Middleweight champion, beating Sugar Ray Robinson for the latter title. Basilio combined technical ability with an aggressive approach; although capable of boxing strategically, he was generally inclined to engage opponents in close-range exchanges. An iron-chinned pressure fighter, Basilio was a combination puncher who had great stamina and eventually wore many of his opponents down with vicious attacks to the head and body.
