Chantelle Cameron delivered a career-defining performance to defeat Mikaela Mayer and unify the WBA, WBC, and WBO light-middleweight titles. The British boxer secured a unanimous decision victory in an closely contested bout, with judges scoring the fight 97-93, 97-93, and 96-94.
Mayer expressed disagreement with the decision, asserting she had outboxed Cameron. The exchange led to a heated moment in the ring, with Mayer suggesting home advantage played a role, a claim Cameron dismissed.
Cameron, who remains undefeated since her 2023 rematch with Katie Taylor, now boasts 23 wins in 24 professional fights. Her strategy of relentless pressure proved effective against the adaptable Mayer, preventing her from establishing a consistent game plan.
While Mayer appeared more imposing early on, Cameron adopted a counter-punching approach before transitioning to the front foot. She cornered Mayer multiple times in the middle rounds, gaining confidence and the support of a vocal home crowd.
By the sixth round, Mayer was bleeding and showing signs of fatigue, struggling to land her jab effectively. Despite sustaining a cut in the later rounds, Cameron pushed through to secure the most significant win of her career since her victory over Katie Taylor in Dublin.
The defeat marks Mayer's third loss in 25 professional fights and results in the relinquishment of her WBA and WBC titles to Cameron.
