Mike Tyson - All Title Fights
Michael Gerard "Mike" Tyson (/ˈtaɪsən/; born June 30, 1966), is an American former professional boxer who competed from 1985 to 2005. He held the undisputed world heavyweight championship and holds the record as the youngest boxer to win the WBA, WBC, and IBF heavyweight titles at 20 years, 4 months, and 22 days old. Tyson won his first 19 professional fights by knockout, 12 of them in the first round. He won the WBC title in 1986 after stopping Trevor Berbick in two rounds. In 1987, Tyson added the WBA and IBF titles after defeating James Smith and Tony Tucker. This made him the first heavyweight boxer to simultaneously hold the WBA, WBC, and IBF titles, and the only heavyweight to successively unify them.
