Mike Tyson's Mansion, Ohio, United States

Tyson made his professional debut as an 18 year old on March 6, 1985, in Albany, New York. He defeated Hector Mercedes via a first round knockout. He had 15 bouts in his first year as a professional. Fighting frequently, Tyson won 26 of his first 28 fights by KO/TKO - 16 in the first round. The quality of his opponents gradually increased to journeyman fighters and borderline contenders, like James Tillis, David Jaco, Jesse Ferguson, Mitch Green and Marvis Frazier. His win streak attracted media attention, leading to his being billed as the next great heavyweight champion. D'Amato died in November 1985, relatively early into Tyson's professional career; some speculate that his death was the genesis of many of the troubles Tyson was to experience later as his life and career progressed.
Tyson's first nationally televised bout took place on February 16, 1986, at Houston Field House in Troy, New York against journeyman heavyweight Jesse Ferguson. Tyson knocked down Ferguson with an uppercut in the fifth round that broke Ferguson's nose. During the sixth round, Ferguson began to hold and clinch Tyson in an apparent attempt to avoid further punishment. After admonishing Ferguson several times to obey his commands to box, the referee finally stopped the fight near the middle of the sixth round. Initially ruled a win for Tyson by disqualification (DQ) of his opponent, the ruling was subsequently "adjusted" as a win by technical knockout (TKO) after Tyson's corner protested that a DQ win would end Tyson's string of knockout victories, and that a knockout would have been the inevitable result. The rationale offered for the revised outcome was that the fight was actually stopped because Ferguson could not (rather than would not) continue boxing.
