​Reigning two-sport ONE World Champion Stella “Always Hungry” Hemetsberger defends her title for the first time against Russian knockout artist Natalia “Karelian Lynx” Diachkova in the main event of ONE Fight Night 46 on Prime Video. The high-stakes slam-dunk in the ONE Women’s Strawweight Muay Thai World Championship takes place in U.S. primetime on Friday, August 14, from Bangkok’s storied Lumpinee Stadium.
Hemetsberger’s ascent from a newcomer on the ONE Friday Fights circuit to a two-sport World Champion stands as one of the most remarkable stories in women’s striking in recent memory. The 27-year-old Austrian fighter, representing RS-GYM and Phuket Fight Club, arrived on the weekly show and wasted no time making an impact, stringing together three straight victories to earn a US$100,000 main roster contract and secure a shot at the biggest stage in the sport. She punctuated that breakthrough by defeating then-ONE Women’s Strawweight Kickboxing World Champion Jackie Buntan over five rounds by unanimous decision to claim the vacant ONE Women’s Strawweight Muay Thai World Title and to become Austria’s first-ever ONE World Champion.
That moment was just the start. Five months later, Hemetsberger returned to the ring against Buntan, this time with the kickboxing belt on the line, and the two produced another brutal five-round war. When the judges’ scorecards were tallied, Hemetsberger again emerged victorious, this time by split decision to capture the kickboxing belt and join Stamp Fairtex and Janet “JT” Todd as the third two-sport queen in ONE history. With a 10-1 career striking record and a flawless 5-0 in promotional competition, the Austrian arrives at her first title defense with extraordinary momentum.
Opposing Hemetsberger is a challenger whose own path mirrors the ascent of the champion. Natalia Diachkova, a 31-year-old Russian from Team Mehdi Zatout, carries a 32-5 career ledger and a 6-1 mark within ONE’s ranks, four of her victories in ONE coming by first-round knockout. Diachkova made a strong impression on the ONE Friday Fights series in 2023, tallying four straight wins to earn a six-figure main roster contract in 2024 and immediately using that momentum to chase gold. Her pursuit paid off with two decisive wins that positioned her right back in the conversation for another shot at 26 pounds of gold.
Diachkova’s hunger and resilience—hallmarks of her promotional journey—make her one of the most dangerous challengers Hemetsberger could face in her first defense. When a two-sport ONE World Champion who has never tasted defeat in promotional competition meets a hard-hitting Russian contender who has already proven she belongs at the sport’s pinnacle, the result is a main event charged with anticipation and potential for a memorable clash. Diachkova’s track record and the momentum she carries into this bout indicate that she will test Hemetsberger in ways that could push the champion to her limits, even as Hemetsberger looks to extend her perfect run inside ONE’s two-division framework.
This matchup promises a fascinating clash of styles: Hemetsberger’s refined Muay Thai and kickboxing versatility against Diachkova’s explosive power and relentless pace. The stage is set for a title defense that could further define Hemetsberger’s legacy as one of the era’s most versatile and dominant two-sport athletes in ONE Championship. Fans around the world will tune in for a battle that has all the ingredients of a dramatic, fight-changing night at Lumpinee Stadium, broadcast under U.S. primetime on Prime Video.
