Floyd Mayweather produced a virtuoso performance to capture Arturo Gatti's WBC light welterweight title in emphatic style in Atlantic City.
Gatti turned his back in round one when protesting to the referee and was forced to take a count after being hit.
The unbeaten Mayweather produced a series of dazzling combinations, an amazing percentage finding the target.
At the end of the sixth, Gatti's camp wisely ended the bout, their man left badly dazed by his stylish opponent.
Britain's IBF champion Ricky Hatton was watching at ringside and described Mayweather's display as "masterful."
Hatton confirmed that he is in discussions with American TV companies over a possible clash with Mayweather.
"I don't see there being a problem," he said.
Mayweather was also keen on the prospect of facing the powerful Mancunian.
"I'll leave it up to my promoters who I fight next, but if me and Ricky Hatton could get it on at Madison Square Garden, that's what I'd like to do," he said.
Mayweather admitted that his derogatory comments towards Gatti in the build-up to the fight were not genuine and been purely to sell tickets.
"I don't hate him at all, I love him," he said. "He's a true champion and he can come back."
Meanwhile, Gatti said he will move up to the welterweight ranks for one last shot at a world title.
