Everything was A-OK for Thailand’s strawweight Muay Thai champion Sam-A Gaiyanghadao at ONE: Reign of Dynasties.

Gaiyanghadao collected an emphatic second-round TKO victory, dropping challenger Josh Tonna with a left straight hand and knocking him down twice more, leaving no doubt to the outcome.

Tonna, a former ISKA K-1 world champion and the current No. 1 contender from Australia, was left perplexed at the champion’s high pace of boxing and high round kicks in the first round.
