Michael Gerard "Mike" Tyson is an American retired professional boxer. Tyson is a former undisputed heavyweight champion of the world and holds the record as the youngest boxer to win the WBC, WBA and IBF heavyweight titles at 20 years, 4 months, and 22 days old. Tyson won his first 19 professional bouts by knockout, 12 of them in the first round. He won the WBC title in 1986 after defeating Trevor Berbick by a TKO in the second round. In 1987, Tyson added the WBA and IBF titles after defeating James Smith and Tony Tucker. He was the first heavyweight boxer to simultaneously hold the WBA, WBC and IBF titles, and the only heavyweight to successively unify them. In 1988, Tyson became the lineal champion when he knocked out Michael Spinks after 91 seconds. Tyson successfully defended the world heavyweight championship nine times, including victories over Larry Holmes and Frank Bruno. In 1990, he lost his titles to underdog James "Buster" Douglas, by a knockout in round 10. Attempting to regain the titles, he defeated Donovan Ruddock twice in 1991, but he pulled out of a fight with undisputed heavyweight champion Evander Holyfield due to injury.
