Double Olympic champ Claressa Shields unifies world boxing titles
Claressa Shields is the undisputed queen of middleweight boxing.
The double Olympic gold medallist added the WBO world title to her collection, by beating Christina Hammer at Atlantic City’s Boardwalk Hall in her native USA.
The unanimous points decision, in what was billed as the biggest fight in women's boxing history, makes the American a four-belt champion in the 72.6kg (160lb / 11st 6lbs) division.
Shields is only the second woman ever to unify all four major titles in the sport since Norway's welterweight champion Cecilia Braekhus.
She's also the sixth fighter in history, male or female, to achieve this feat.
Her professional record improves to 9 wins (2 KOs) and no losses.
It was Hammer's first defeat as a pro, taking her record to 24-1 (11 KOs).
The 24-year-old from Flint, Michigan, has already set her sights on the next opponent.
"Women's boxing, we're on fire. I cannot wait to see the next super fight. Give me Cecilia Braekhus at 154 pounds. That’s who I want next. Either her or Savannah Marshall." she said in the after-fight press conference.
British super middleweight champion Marshall is the only fighter ever to beat Shields, when she was still an amateur, at the World championships in 2012.
"I’ll go to the UK and beat Savannah Marshall,” Shields added. “Bring me her. Bring it to me."
