Audley Harrison gained his 14th straight win as a pro thanks to a third-round win over American journeyman Brian Nix in Nevada.
The bout was scheduled to be Harrison's first 10-rounder, but he needed less than eight minutes to see off an opponent who had lasted seven rounds with former world title challenger Andrew Golota in August.
Harrison softened up Nix with his right jab for the first two rounds before opening up with some neat left uppercuts in the third.
Nix rose off the canvas once but Harrison finished the job off with a classy combination.
"In the first two rounds I was trying to use my jab and working on keeping him at range," said Harrison.
"In the third round I wanted to show something different and use the other things I have been working on to put him away.
"I was being a bit merciful in the first two rounds but took advantage of my full arsenal early in the third round to demonstrate my dominance."
Harrison has not fought in Britain since last May but is hoping to settle a few old scores back at home in 2004.
After three wins across the Atlantic, he has set his sights on dethroning British heavyweight champion Danny Williams next year.
Harrison added: "Back in the UK, there are a few domestic rivals that have been calling me out, such as Danny Williams.
"Politics aside, I would like to contest for the British title next year, as well as keep busy in America with the other up and coming heavyweight contenders.
"As a professional you haven't seen the best of Audley Harrison yet. I am on course, still learning and getting better in the professional game with each fight.
"As everyone can see, I have the talent, continue to make a statement and truly believe that I will be the heavyweight champion of the world within the next two years."
