Teenage grappling prodigy Helena Crevar will meet eight-time BJJ world champion Kendall Reusing for the inaugural ONE Women’s Openweight Submission Grappling World Title at ONE Fight Night 51 on Prime Video.
The 10-minute championship bout takes place live in U.S. primetime on Friday, January 8, from Lumpinee Stadium in Bangkok, Thailand.
At just 19 years old, Crevar has quickly established herself as a force in women’s submission grappling. The Kingsway Jiu-Jitsu product holds multiple IBJJF World and No-Gi World titles, building a reputation for relentless back control, an intricate guard, and a sharp finishing instinct.
Under the guidance of John Danaher, Crevar earned the distinction of becoming the coach’s first female black belt after ascending from purple belt in less than a year. That technical foundation carried directly into her tenure under ONE Championship.
She submitted Teshya Noelani Alo via Estima Lock in just 100 seconds at ONE Fight Night 39, followed by a one-sided unanimous decision victory over Paige Ivette Clymer at The Inner Circle 22 in July to move to a 2-0 record.
Her path to the openweight throne also includes a bracket-clearing run at the 2026 ADCC World Championship in Krakow, where she submitted all three of her opponents to claim +65kg gold and become the youngest ADCC Champion in history. That leaves 26 pounds of ONE gold as the lone accolade missing from her resume.
Standing across the mat is Reusing, a seasoned pioneer who captured the inaugural Polaris Women’s Openweight title in 2021 and successfully defended it in March. A black belt under her father, Tom, the 29-year-old Gracie Barra standout brings a deep wrestling background featuring a California state title, four U.S. national titles, and experience on Team USA’s international circuit.
Outside of competition, Reusing works as a grappling commentator and podcast host, bringing an analytical approach to a matchup that pairs youth against veteran experience. Both athletes have shaped women's openweight grappling, leaving fans to watch how the tactical chess match unfolds when they collide in Bangkok.
