Las Vegas, Nev., May 30--Mike Tyson successfully defended his heavyweight title when he knocked out Pinklon Thomas here in two minutes of the sixth round of a scheduled twelve-round fight.
The end came on a five-punch sequence that was vintage Tyson--powerful, and sprawling. A right uppercut landed flush on Thomas's jaw, but with it Tyson's weight shifted onto his heels so that when he threw a snappy left hook, it was while drifting backward--a brush stroke. Even so, it hurt the Pink Man.
Tyson corrected his balance and let fly the last three punches--a short left hook that landed flush on Thomas's chin, a right that didn't, and, with his legs spread wide, a final left hook to the chin that had the full measure of his body behind it. Thomas went down.
Onto his back he fell, his eyes closing shut and his arms outspread. Now he tried to recover from the terrible impact. . . .
By HBO's original plan, Tyson was not to have fought an optional title defense on May 30. That date had been set aside
