American boxer Claressa Shields has scored a unanimous points victory over Canada's Marie-Eve Dicaire to become the first undisputed world boxing champion in two different divisions in the four-belt era.
Shields, 25, retained her WBC and WBO light-middleweight titles, won the vacant WBA belt and also took Dicaire's IBF crown after all three judges at the Dort Federal Event Centre in Flint, Michigan, scored Friday night's fight 100-90 in the American's favour.
"I was trying for the knockout," said Shield, who landed 116 punches to Dicaire's 31. "That's what I wanted. And I almost had it...at the end of the day, I'm the new undisputed champion at 154 pounds - the first boxer to do it in history."
Shields, a two-time Olympic champion, had previously unified all four major belts - WBC, WBA, IBF and WBO - at middleweight.
After the fight, she was quick to call out Britain's Savannah Marshall, the only fighter to have defeated Shields as an amateur.
"You won a lucky decision when we were kids," Shields said.
She has called herself the G.W.O.A.T. - Greatest Woman of All Time - and the day before the fight, proclaimed herself to be history's second-best fighter, behind only Muhammad Ali.
