Cameron Unifies Super-Welterweight Titles with Points Win Over Mayer in Birmingham
Chantelle Cameron unified the world super-welterweight titles on 29 August 2026, beating Mikaela Mayer by unanimous decision at the Pulse Live Arena in Birmingham.
Cameron added Mayer's WBC and WBA belts to the WBO strap she already held, making her a unified champion — the term for a fighter who holds more than one of boxing's major world titles at the same time. Judges scored the 10-round contest 97-93, 97-93 and 96-94, all in Cameron's favour (The Guardian).
The fight headlined the MVPW-06 event, a UK-versus-USA card promoted by Most Valuable Promotions, with each round scheduled at two minutes under the 154-pound super-welterweight limit (Most Valuable Promotions). Cameron, now 22-1 with 8 knockouts, claimed the vacant WBO title in April with a unanimous decision over Michaela Kotaskova (Yahoo Sports). Her only career defeat came against Katie Taylor in 2023.
The co-main event delivered its own drama. Caroline Dubois retained her WBC and WBO lightweight titles with a dominant points win over Amelia Moore, with judges' scorecards reading 99-90, 99-90 and 98-91. The margin reflected a one-sided night for Dubois, who dropped just a single round on two of the three cards.
What happened next needed no rounds to generate heat. Alycia Baumgardner — the WBA, WBO and IBF champion at 130 pounds — had moved up to lightweight to challenge Dubois and was ringside. After the decision was announced, the two exchanged words in a heated confrontation at ringside. Baumgardner described Dubois's performance as lacklustre, setting the stage for a potential showdown between two of women's boxing's most decorated champions (The Guardian).
For Cameron, the Birmingham result writes a clean new chapter after the Taylor defeat. She walked in with one belt and left with three, having outpointed a respected champion over 10 rounds on home soil. For Mayer, the loss halts her reign at super-welterweight and sends her back to the drawing board.
For fans, the Dubois-Baumgardner exchange may be the night's real trailer. Baumgardner holds three belts three divisions below where she now wants to fight. Dubois holds two at lightweight. If the fight gets made, the belts — and the bad blood — will travel with it.
