It's lights out for Francois Botha after a flurry of Joseph Parker punches.

Too quick. Too powerful.

Joseph Parker delivered spectacular confirmation he is, indeed, the future of New Zealand boxing by knocking out Francois Botha in the second round tonight.

Parker wanted to fight like a big man. He did just that - and more.

There couldn't have been a more definitive result than this.

In front of an animated home town crowd, Parker handed Botha just the eighth TKO and 10th loss of his 23-year professional career.

The 21-year-old Parker, who gave up 14 kilograms, hit Botha with six thunderous punches before he hit the canvas. It was a dramatic stoppage few predicted.

The South Africa veteran was out cold. He needed to be helped to his stool more than a minute after hitting the floor. The 44-year-old looked a shadow of the man that fought some of the biggest names in the sport, including Mike Tyson, Lennox Lewis, Evander Holyfield and Wladimir Klitschko. He looked destined for a rest home.

While there were never any doubts about Parker's speed, this should put to bed question marks about his power. Botha was thought to be a durable fighter. Not tonight. Parker proved he can pack a punch. That will be the lingering memory.

Two months training under Kevin Barry in Las Vegas clearly paid off. Despite approaching his first eight-round fight, all week Parker seemed cool, calm; in total control. That was reflected in the most convincing win of his fleeting six-fight pro career.

All doors are now open.
