Up until Friday night, Regian “The Immortal” Eersel hadn’t competed under Muay Thai rules for four years. But that was hard to tell when witnessing his history-making performance in “the art of eight limbs.”
The ONE Lightweight Kickboxing World Champion scored a split-decision win against undefeated Thai sensation Sinsamut Klinmee to capture the inaugural ONE Lightweight Muay Thai World Title and become a two-sport king in the process.
His career-defining display went down in the co-main event of ONE on Prime Video 3: Lineker vs. Andrade, which broadcast live from the Axiata Arena in Kuala Lumpur, Malaysia, on October 21.
Both men began the five-round banger with intense patience, as they picked their shots, avoided mistakes, and read their rival’s movements. Then, a right hand from Eersel stunned Sinsamut and reminded the Thai dynamo who he was standing across from.
Eersel rode that glimmer of momentum into the second frame, where he came to life with blistering boxing combos followed by low kicks. Surprisingly, Sinsamut hung back and chose to absorb the punishment, focusing solely on finding a hole for his knockout blow.
Unsuccessful in dismantling “The Immortal” with his original approach, the Thai changed tactics in round three. He increased his output and started landing his own punch combinations and low kicks, which turned Eersel’s leg purple like grape jam.
The surging contender continued to attack Eersel’s lead leg in the fourth round. Meanwhile, the lightweight kickboxing king struggled to find the same success he had in the opening stages of the bout. It appeared, for the first time, that Sinsamut could pull ahead in the World Title affair.
But Eersel – the five-time ONE Lightweight Kickboxing World Champion – had been in these situations before, so he knew exactly what to do. In the final canto, he smothered his opponent with punches and low kicks, giving Sinsamut almost no chance to strike.
After 15 minutes of action, two of the three judges scored the split decision for Eersel, who moved his record to 59-4 and made history as the organization’s first-ever ONE Lightweight Muay Thai World Champion.
