ONE Championship 2025 Calendar Starts Below ONE Fight Night 27will be broadcasting live from the iconic Lumpini Boxing Stadium in Bangkok, Thailand, this Friday, January 10th. The main card will air on Amazon Prime at 8pm ET and will feature two key atomweight WMMA matchups.
Interim Atomweight Title Co-Main Event: Dennis Zamboanga vs. Alyona Lassogina

In the co-main event, No. 2 ranked Dennis “The Menace” Zamboanga will take on No. 4 Alyona Lasogina for the interim atomweight title. The stakes are high, with the winner earning a future showdown with reigning champion Stamp Fairtex later this year.
Zamboanga, a 27-year-old Filipino standout, has a professional record of 11-2 and is riding the momentum of a three-fight winning streak. Known for his tenacious style and rapid rise, Zamboanga is hungry for a chance to win his first world title.
Lasso Haina, on the other hand, brings veteran knowledge and submission expertise. The 34-year-old Ukrainian owns a 13-5 record, coming off a narrow split decision loss to Stamp Fairtex in the rematch. Of note, Lassohaina submitted a stamp in the first meeting, making the intriguing prospect of a trilogy match a reality if she wins on Friday. This marks Lassohaina’s return to competition after a three-year hiatus due to pregnancy, adding an exciting layer to her comeback journey.
Chihiro Sawada vs. Menbo: Clash of styles


Another exciting atomweight matchup pits rising star Chihiro Sawada against the experienced Meng Bo. The match features a classic style clash of Sawada’s wrestling and Meng’s striking.
Sawada, 27, is a Japanese prodigy with a perfect record of 8 wins and 0 losses. The wrestling specialist quickly rose through the ranks and earned her spot as ONE’s No. 3 atomweight contender. Her grappling-focused approach has stifled all her opponents so far, and she will look to do the same against her Chinese opponent.
Meng Bo, who will be making his atomweight debut, has a wealth of experience with a record of 21 wins and 7 losses. A dangerous striker, she is best known for her first professional loss to current UFC strawweight champion Zhang Weili. Meng, 28, hopes to make an immediate impact in her new weight class and establish herself as a championship favorite.
Big bet in the atomweight division
These two matchups are crucial in shaping the future of ONE’s atomweight division. With Stamp Fairtex out, Friday night is the perfect stage for Zamboanga, Lassohaina, Sawada and Meng Bo to stake their claim as the next big thing in the 105-pound division.
