Reinier de Ridder became a two-division champion at ONE on TNT IV, besting light heavyweight titleholder Aung La N Sang.
De Ridder, the reigning middleweight champion, scored a victory in the main event on TNT.
De Ridder brought Aung La N Sang to the mat at will for much of the fight, scoring with a variety of takedowns while threatening with a plethora of submission attempts. The Myanmar icon defended well against those attempts, but the man from the Netherlands proved far too skilled on the mat.
“The Dutch Knight” built on his lead with each passing round. In the fifth and final frame, Aung La N Sang was able to reverse positions on the ground to end up on top. But with only a few minutes remaining, “The Burmese Python” was unable to mount a comeback.
In the co-main event, Ok Rae Yoon topped Eddie Alvarez via decision.
Alvarez closed the distance with multiple shots that led to clinch situations, but Ok defended well against the Circle Wall. In the first round, Ok hurt Alvarez with a punch that sent him crashing to the canvas, where the South Korean nearly found the finish with ground-and-pound. Alvarez survived and was aggressive in the next two frames, but in the end, all three judges scored the bout in favor of Ok to win by unanimous decision.
