Featuring five MMA matches and one Muay Thai title bout, “ONE: Reign of Dynasties” was a closed-door event held at the Singapore Indoor Stadium in Kallang, Singapore on October 9, 2020. In the main event of evening, Josh “TimeBomb” Tonna, 32, of Australia challenged the reigning ONE Strawweight Muay Thai World Champion.

Johnny Chan served as the referee. Sam-A appeared composed and relaxed to start the bout, delivering a volley of fast boxing combinations and high round kicks in the first round.


In the beginning of the second round, Sam-A dropped Tonna with a bullet-like left straight, sending the Australian challenger to a mandatory 8-count. Sensing he had his opponent hurt, the defending champion poured on the pressure and dropped his challenger two more times en route to a technical knockout victory.

Chan put a stop to the title bout after 2 minutes and 30 seconds in the second round when Sam-A knocked out Tonna. It was the first successful title defense of the Thai defending champion, who is also the reigning ONE Strawweight Kickboxing World Champion.
