Stella Hemetsberger’s Muay Thai Title Defense vs Diachkova

Hemetsberger’s Path to the Spotlight

At 27, the Austrian from RS‑GYM and Phuket Fight Club arrived on ONE Friday Fights as a complete newcomer. She rattled off three consecutive victories, earning a US$100,000 main‑roster contract and an immediate shot at the sport’s biggest stage. Her breakout moment came when she edged Jackie Buntan by unanimous decision to capture the vacant ONE Women’s Strawweight Muay Thai World Title, becoming Austria’s first-ever ONE World Champion.

Five months later Hemetsberger returned to the ring against Buntan for the kickboxing crown, surviving a grueling five‑round saga and securing a split‑decision win. That victory placed her alongside Stamp Fairtex and Janet “JT” Todd as the third fighter to hold both Muay Thai and kickboxing belts in ONE history. With a flawless 5‑0 promotional record and a 10‑1 overall striking ledger, she enters her first title defense on a wave of momentum.

Diachkova’s Hard‑Fought Challenge

The Russian knockout specialist Natalia “Karelian Lynx” Diachkova, 31, brings a different kind of intensity to the main event. From Team Mehdi Zatout, she boasts a 32‑5 career record and a 6‑1 ONE résumé, hitting four first‑round knockouts along the way. After four straight wins on ONE Friday Fights in 2023, Diachkova earned a six‑figure contract in 2024 and quickly positioned herself for gold.

Her initial World Title bid fell short, but she rebounded with two decisive victories that kept her in the mix for another shot at the coveted belt. Known for her relentless pressure and raw power, Diachkova is considered one of the most dangerous challengers Hemetsberger could face.
