World champion Claressa Sheilds has made boxing history.
Her unanimous points victory over Marie-Eve Dicaire meant that she became the first fighter - male or female - to be undisputed champion in two divisions in the four-belt era.The fight was held in Shield's hometown of Flint, Michigan. The fight was also the headline act of the first ever all-women pay-per-view boxing card.
All three judges scored the fight 100-90 for Shields, who landed 116 punches to Dicaire's 31.
The victory meant the 25-year-old retained her WBC and WBO light-middleweight titles, took Canadian Dicaire's IBF crown and won the vacant WBA belt.
She had already won all four belts at middleweight.
After the fight Shields called out Britain's Savannah Marshall, the WBO middleweight champion and the only women to beat her as an amateur.
