Twenty years after Mike Tyson battered Trevor Berbick to become the youngest heavyweight world champion in history, the "Baddest Man on the Planet" is aging as badly as any boxing cautionary tale.
Tyson was 20 years old on November 22, 1986 when he pummeled Berbick into submission in two rounds, seizing the World Boxing Council crown that the Jamaican had held for only eight months.
"I'm the youngest heavyweight champion in the world," Tyson told his co-manager in the ring, "and I'm going to be the oldest."
Tyson's prediction of longevity proved premature, but certainly his brutal dominance for a time electrified what had become a stagnant division.
He arrived at the Berbick fight already surrounded by an aura of menace, undefeated in 27 professional fights -- with most of those wins coming by way of ferocious knockouts. The experienced Berbick had no answer for Tyson's determination and power.
Tyson hurt him in the first round and continued the punishment to body and head in the second, finally sending Berbick sprawling with a left hook to the temple.
Berbick tried to rise twice before finally getting his wobbly legs under him, but referee Mills Lane judged him unable to continue.
