Teen Tiah‑Mai Ayton Aims to Be Youngest Undisputed Champion as She Prepares for Second Pro Fight

Tiah‑Mai Ayton, 19, has publicly set her sights on becoming the youngest undisputed world champion in the four‑belt era as she prepares for her second professional boxing bout on Saturday.

Ayton, who won her professional debut by third‑round stoppage in June 2025, said she could match or better the mark set by Gabriela Fundora, who held all world flyweight titles at age 22 in November 2024. "I can definitely do that," Ayton said when told of Fundora's achievement. "That's going to be a new challenge for me. I've got a long time."

A Bristol native, Ayton arrives in professional boxing with an extensive close‑contact background. She has competed in more than 300 fights across Muay Thai, mixed martial arts, kickboxing, jiu‑jitsu and boxing, suffering only three defeats that she later avenged, according to her team. She will face Lydie Bialic in her second pro contest as she steadily builds experience in the paid ranks.

The ambition to secure all four major belts — the WBA, WBC, IBF and WBO — is rare in boxing and has been achieved by only a handful of fighters in the modern era. Fundora’s November 2024 unification attracted attention for her age; Ayton’s public declaration underscores how quickly careers in women’s boxing can accelerate. Fellow Briton Nina Hughes captured a world title in just her fifth professional fight, demonstrating the rapid trajectory possible in the division.

Ayton’s move into professional boxing follows a decorated amateur and multi‑discipline career, during which she gained experience across several striking and grappling sports. Her team has emphasised a long‑term plan to develop her skills and manage her progression through increasingly challenging opponents.

Promoters and trainers in women’s boxing have in recent years pursued unification bouts more actively, creating opportunities for young fighters to contest multiple titles earlier in their professional journeys than in past decades. Ayton’s statement of intent is notable both for her youth and for the breadth of her combat sports background, which her supporters say gives her a diverse skill set as she adapts to the professional ring.

Ayton’s second professional fight will be watched by those tracking fast‑rising talents in women’s boxing and by observers interested in whether a teenager can close the gap on established champions while following a careful developmental path. She has not yet outlined a timetable for a title run, but her comments indicate a clear long‑term objective of pursuing undisputed status in her weight class.

Her bout on Saturday will offer an early measure of how quickly she can progress in the professional ranks and how effectively her multi‑discipline experience translates into sustained success under the four‑belt championship system.
