Kiwi-Tongan Junior Fa has won the WBO International heavyweight belt with an impressive TKO victory over French fighter Newfel Ouatah in Columbus, Ohio.
The 29-year-old knocked Ouatah to the ground four times in the first round, giving the referee no choice, but to call the fight.
The fight was Fa's first lead role on a US card, coming at the Arnold Sports Festival, an annual event sponsored by former bodybuilding movie star Arnold Schwarzenegger.
The WBO International belt was previously held by Briton Dillian Whyte, who successfully defended it against Parker last July, but vacated the title, when he became the top-ranked challenger to WBO champion Anthony Joshua.
The win improves Fa's record to 17-0 and he is now expected to take a step up in class for his next fight.
In an earlier fight, Kiwi boxer Hemi Ahio impressed in his first fight on US soil, defeating Ed Fountain by TKO to improve his record to 13-0.
The New Zealand heavyweight champion dominated the entire fight and took it to another level to end the fight in the penultimate round.
