5 Reasons To Watch ONE Fight Night 41: Sinsamut Vs. Jarvis On March 13

Bangkok’s Lumpinee Stadium will roar back into U.S. primetime this Friday, March 13, when ONE Championship presents ONE Fight Night 41: Sinsamut vs. Jarvis live on Prime Video. Nine bouts spanning Muay Thai, MMA, submission grappling, and kickboxing promise non-stop action from the first bell to the final buzzer. Here are the five biggest reasons to clear your calendar and tune in.

1. A make-or-break Muay Thai headliner Former World Title challengers Sinsamut “Aquaman” Klinmee and George “G-Unit” Jarvis collide in a lightweight showdown that doubles as a de-facto eliminator for Regian Eersel’s ONE Lightweight Muay Thai crown. Sinsamut, 30, carries an 83-21 ledger and four knockouts in five ONE appearances; Jarvis has forged his reputation through six all-action global bouts. Both men are rebounding from recent defeats, guaranteeing desperation-level intensity and the possibility of a single-shot finish.

2. Tye Ruotolo’s submission-grappling throne on the line Welterweight king Tye Ruotolo, the youngest IBJJF World Champion ever, puts his ONE Submission Grappling belt at risk against Polish prodigy Pawel Jaworski. Ruotolo is 10-0 inside the Circle across grappling and MMA, while Jaworski owns the 2025 IBJJF No-Gi World title at 85 kilograms plus double gold at the European No-Gi championships. Leg-lock artistry meets dynamic athleticism in what could be the quickest finish of the night.

3. John Lineker’s striking reinvention Former ONE Bantamweight MMA champion John “Hands of Stone” Lineker has reinvented himself as a featherweight kickboxer, scoring back-to-back knockouts before dropping competitive decisions to elite stand-up stylists. Opposite him stands promotional newcomer Ben Woolliss, a Grimsby technician eager to announce his arrival by defusing one of the sport’s most feared punchers.

4. Hyu Iwata’s pursuit of perfection Japan’s 23-year-old phenom Hyu Iwata brings a 12-0 record and a growing highlight reel of spinning attacks into a flyweight kickboxing bout against Thailand’s Suablack Tor Pran49. Suablack, once a six-fight ONE winner at bantamweight, drops to flyweight seeking career victory No. 63 and the upset that would shatter Iwata’s unblemished aura.

5. Women’s History Month spotlight The atomweight division delivers two pivotal match-ups. In Muay Thai, Anna “Supergirl” Jaroonsak hunts her 41st career win opposite Hong Kong’s Yu Yau Pui, who looks to halt a two-fight skid. In MMA, Brazilian contender Victoria Souza—fresh from maternity leave and riding consecutive victories—faces undefeated Canadian debutant Anastasia Nikolakakos, who owns five straight wins and dreams of a statement upset.

From World Title ramifications to career crossroads, ONE Fight Night 41 offers storylines and firepower worthy of the historic Lumpinee canvas. The action begins Friday night, exclusively on Prime Video.
