British heavyweight Audley Harrison easily got the better of American journeyman Robert Wiggins in his latest fight in San Jose on Thursday.
Harrison dominated Wiggins for most of the four rounds
Harrison disposed of his opponent with a fourth-round technical knock-out.
The first two rounds went Harrison's way, although Wiggins showed more aggression in the third.
Harrison caught his opponent with a straight left in the fourth round, knocking him down, and Wiggins was never able to recover from that.
"I felt really comfortable tonight and was able to use my boxing skills to come out early and establish my jab and take it right to him," said Harrison.
"My left hand was working for me all night and I felt it was only a matter of time before it was going to do the damage it did."
He added: "I'll take on all comers because I know I am the best the division has to offer," said Harrison.
"It won't be long until I am on sitting on the mountain top."
It was the 19th professional victory for the 33-year-old who has been criticised for slow progress in the pro ranks since becoming an Olympic champion in 2000.
He now has his sights on Sam Peter and Calvin Brock as possible opponents.
Unbeaten Nigerian Peter meets Wladimir Klitschko in September, while Brock has 26 straight wins, including those over Jameel McCline and Clifford Etienne.
"My offers remain open to Brock or Peter if they believe I am just all talk," said Harrison.
"Forget money, location, network, to me it is all about pride and confidence."
