Marie McManamon returns to Lumpinee Stadium carrying the weight of ONE World Championship heartbreak and the burning determination to prove her title defeat was merely education rather than limitation.

The English-Irish sensation faces WBC Muay Thai World Champion Selina Flores in atomweight action at ONE Fight Night 36 on Friday, October 3, with both women understanding that spectacular performances could reshape their futures entirely.

McManamon’s promotional debut delivered the kind of learning experience that either destroys fighters or makes them tougher. Her fourth-round TKO loss to reigning ONE Women’s Atomweight Muay Thai World Champion Allycia Hellen Rodrigues at ONE Fight Night 29 revealed both her technical limitations and heart.

The London-based striker proved she belonged on the sport’s biggest stage while discovering exactly what separates elite contenders from World Champions. Her performance showcased the solid clinch game and deep gas tank that made her one of the United Kingdom’s top exports.

Training alongside reigning ONE Bantamweight Kickboxing World Champion Jonathan Haggerty at Knowlesy Academy has provided perspective during her preparation for this crucial comeback opportunity. The months since her defeat have been spent addressing the technical deficiencies that prevented her from capturing gold.

Flores represents the perfect test for McManamon’s improvements. “The Teep Queen” arrives as one of only three American athletes to capture WBC Muay Thai World Championship gold, earning that distinction through masterful distance control and technical precision.

The 27-year-old San Diego native proved her credentials by successfully defending her WBC strap against Barbara Fersan in Mexico this past February, demonstrating the kind of pressure performance needed for elite success.

Her signature teep kicks and smooth technical superiority have made her a dominant force in American Muay Thai competition, but ONE Championship represents an entirely different level where proven fighters regularly face shocking defeats.

McManamon possesses the tools necessary to drag opponents into deep waters where her superior conditioning and clinch game create late-round advantages. The question is whether her technical improvements can neutralize Flores’ distance management long enough to implement her physical advantages.

Both women carry championship-level skills and desperate motivation into this atomweight collision that promises technical excellence and competitive fire until someone’s will breaks under Lumpinee’s unforgiving lights.
