In the main event of ONE Friday Fights 9, the promotion’s most recent show of its weekly events at the venerable Lumpinee Stadium, two-division ONE world champion Regian Eersel gave a performance to remember.

In order to avenge his October fight with Thai fighter Sinsamut Klinmee, the current ONE flyweight Muay Thai world champion entered the Circle. At ONE on Prime Video 3, Regian Eersel won the championship against Klinmee in a competitive match, but at ONE Friday Fights 9, the outcome was considerably more clear-cut.

Regian Eersel managed to pull off the ideal outcome at Sinsamut Klinmee’s homeland, no less, in their much awaited rematch.

After a stunning fourth-round knockout of Sinsamut that left the spectators inside the venerable Lumpinee Boxing Stadium in complete shock, the Surinamese star successfully defended the ONE lightweight Muay Thai world title.

Their battle came to a conclusion when Regian Eersel successfully knocked out his opponent in the fourth round to retain his championship and extend his winning streak to 21 fights in a row, including a 9-0 record under the ONE Championship banner.

In the fourth round, Regian Eersel quickly identified the opportunity. A left hook from “The Immortal” that connected with “Aquaman’s” solar plexus 1:17 into the round ended the contest as he realised Sinsamut was running on fumes.

The Thai celebrity had no chance of standing up again because the shot had such a significant impact.

Regian Eersel defeated Sinsamut Klinmee in a close split decision match for the first ONE lightweight Muay Thai world title at ONE on Prime Video 3. The fight’s tight outcome was intended to lead to a rematch, and the current world champion made sure that there was no room for uncertainty in their second encounter.

Following his remarkable victory, “The Immortal” spoke with the promotion, revealing his thoughts on the outcome and praising his opponent for being a tough opponent.

“I feel very good, I’m a happy man now. It was a tough fight, my respect to Sinsamut – he came better this time. He was well-prepared, he hit me with the kicks. But I knew in the championship rounds, nobody can survive my condition. I saw that he was tired, so I had to go to the body, and I did.”

At only 30 years old, Eersel has already proven to be one of the most dominant competitors in ONE Championship history, defeating every opponent that has ever shared the Circle with him.

Regian Eersel thinks that the outcome was determined by his better fight IQ

Regian Eersel may not be known for his finishing moves, but every time he competes, “The Immortal” dazzles the crowd with his masterfully executed game plans and superior fight IQ. In fact, he believes that his defeat over Sinsamut Klinmee on Friday night at the storied Lumpinee Boxing Stadium was the result of his superior battle intelligence.

When asked why he felt sure about winning a knockout victory on Friday, Eersel responded, “My fight IQ. No disrespect, but I know that I’m smarter than him, as you saw. And my game plan worked perfectly. I took some damage, but that’s part of the game.”

The powerful body shot knockout of Klinmee by “The Immortal” earned him a $50,000 prize for his outstanding performance. When Eersel learned the news, he was extremely grateful and thanked ONE CEO Chatri Sityodtong.

He said, “Thank you Chatri, thank you ONE for the opportunity to fight. This is my favorite organization.”
