It took just three rounds and a few seconds of the fourth for Shane Cameron to defy the odds and see the threat from American Monte Barrett off.
Barrett was clear pre-fight favourite, but Cameron allowed none of it to perturb.
Pre-match, he had cited his preparation for the fight as "superb" and last night's result cannot argue with his words.
The win means Cameron reclaims the WBO Asia Pacific heavyweight title, as well as the WBO Oriental heavyweight title.
