Gabriela Fundora became the first undisputed flyweight champion in the four-belt era following a seventh-round TKO victory over Gabriela Celeste Alaniz on Saturday in Las Vegas.
Fundora (15-0, 7) dominated the fight and sent Alaniz to the canvas with a straight left hand to the chin 1:08 minutes into the seventh round. Alaniz got up quickly, but 20 seconds later, she was dropped again with the same punch, forcing the referee to stop the fight. At the time of the stoppage, Fundora was up in all three judges' scorecards 58-56, 59-55 and 58-56.
Fundora was the IBF champion entering the fight and the victory was her third KO win in her last four fights. Alaniz (15-2, 6 KOs) had won the WBC, WBO and WBA with a split decision over Marlen Esparza in a rematch back in April.
With the victory, Fundora overtakes Alaniz for the No. 1 spot at flyweight.
Also on Saturday, in Birmingham, England, former undisputed junior welterweight champion Chantelle Cameron defeated Patricia Berghult by unanimous decision to get back on track.
Cameron (20-1, 8 KOs), the WBC interim junior welterweight titlist, won by scorecards of 100-90, 99-91 and 98-92. It was Cameron's second consecutive victory since losing her tiles to Katie Taylor in November 2023. Cameron stays at No. 2 in the division behind Taylor.
Rankings will be updated every Tuesday. They'll be based on recent bouts, head-to-head competition and the quality of opponent. As with almost everything, until fighters square off against one another, there is a layer of subjectivity to it. Fighters who haven't fought in 18 months and don't have a fight scheduled will be removed from the rankings until they fight again.
