Undefeated Dutchman Reinier de Ridder is now a two-division champion, adding ONE’s light heavyweight belt to the middleweight title he already owns with a decision win in the main event of ONE on TNT IV, which aired Wednesday in the U.S.

And de Ridder (14-0) earned both belts by taking them away from Aung La N Sang (26-12) – the latest in a one-sided decision win at Singapore Indoor Stadium.

At the opening bell, de Ridder moved immediately forward and was able to drag the action to the canvas, scrambling through a seres of attempted escapes before setting up on top of N Sang’s half-guard. After advancing to mount shortly after, de Ridder was able to take the back when his opponent rolled. The body triangle came in immediately after, and de Ridder went to work on a potential choke.

To his credit, N Sang defended his neck well despite being in a bad position. In reply, de Ridder simply punched away to soften things up before beautifully transitioning to an arm-triangle attempt. N Sang defended it perfectly and was able to move back to the feet and deliver a few big punches before perhaps surprisingly choosing to engage again on the floor.

In the second frame, de Ridder again shot inside immediately, but N Sang was able to defend the initial effort. As de Ridder continued working in tight, he did get the occasional takedown, but he wasn’t able to keep the fight on the canvas until past the halfway mark of the frame, when he was finally able to secure top position and step quickly to mount.

N Sang rolled to escape and did get back to his feet, but de Ridder took him down again and finished the frame on top.

The third saw de Ridder get the fight to the floor with relative ease, where he dominated the positioning. N Sang kept himself out of submission trouble, but he wasn’t able to muster any offense of his own. He worked back to his feet late in the round, but even then, he was simply stuck against the cage.

The fourth round was a carbon copy of the first three, and the final frame started out exactly the same. N Sang was able to sweep to the top with three minutes left, but he was unable to muster any offense in the position, and de Ridder cruised to a one-sided decision win, claiming his second ONE Championship belt – and announcing his intention to get a third by coming after current heavyweight titleholder Brandon Vera.

The ONE Championship struggles continue for Eddie Alvarez (30-8), who fought his heart out in an all-out brawl but ultimately suffered a unanimous-decision loss to Rae Yoon Ok (15-3).

Alvarez attacked the legs of the taller Ok in the early going before driving forward and taking the fight to the floor. Ok stood quickly, and the battle in the clinch began. Ok was up to the challenge, and Alvarez was forced to back away and strike with the bigger man. It proved to be a dangerous proposition.

As they engaged on the feet, a massive two-punch combination from Ok sent Alvarez to the floor and seemed destined to end the fight. The South Korean set up on top and unleashed a non-stop barrage of hammerfists and straight punches. The referee gave Alvarez every opportunity to recover, and he did, taking an unbelievable amount of damage but refusing to quit.

Sensing he wasn’t going to be awarded the finish, Ok returned to the feet in the final 30 seconds, and Alvarez unbelievably was able to mount some offense just before the bell.

Alvarez was quick to the takedown in the second, but Ok remained up to the challenge. Even when Alvarez did get his opponent briefly down, Ok would work right back to his feet. Alvarez struggled to really get any effective offense logged, but he was the aggressor, even if Ok was able to defend most of it by simply setting up on the cage and staying upright.

Alvarez seemed the fresher man in the third, and he started mixing up his attacks, faking a few takedowns and driving in uppercuts and overhands depending on the read. Clearly fatigued, Ok dug deep and found the energy for a few knees and kicks up the middle while continuing to defend the takedown. In the closing seconds, the two stood toe-to-toe and took turns checking the chin to end an absolute brawl of a fight. In the end, though, the early damage proved too much to overcome for Alvarez, and judges awarded Ok the win via unanimous decision.

Viral star ‘Reug Reug’ suffers odd defeat

In a battle of undefeated heavyweights Kirill Grishenko (4-0) was able to earn a somewhat bizarre victory over Senegalese wrestling sensation Oumar Kane (3-1), better known as “Reug Reug.”

It was Grishenko who was the aggressor early, and he showed solid takedown defense when Kane immediately changed levels and worked from the clinch for a takedown. The position proved a stalemate, and the two would eventually reset, where Grishenko would score a couple of quick strikes before being forced to defend a takedown once again.

Kane clearly slowed as the round wore on, and Grishenko scored with a big kick to the thigh and a spinning backfist before the bell.

The second round was more of the same, with Grishenko landing big strikes when given space and then capably defending takedown attempts in the clinch. A frustrated Kane tried to land a few clubbing shots each time he would release the clinch, but he found himself unable to cause any real damage.

Controversy surrounded the ending sequence of the frame, as Grishenko landed a right hand to his opponent’s throat just after the bell, and Kane protested before dropping to the canvas. When Kane couldn’t answer the bell for the third, Grishenko was awarded a TKO win.

Shinya Aoki, Colbey Northcutt pick up submission wins on prelims

Submission wizard Shinya Aoki (47-9) closed out his trilogy with fellow former ONE champ Eduard Folayang (22-11) in style, scoring a first-round submission via armbar.

After a brief feeling out process to start the contest, Aoki was able to work inside to the clinch and eventually trip the action to the canvas, working quickly to mount. Once there, the end seemed almost inevitable, with Aoki controlling from the top before setting up the armbar and turning for the submission, cranking on the limb until earning the stoppage with 40 seconds left in the first round.

In the night’s first prelim, vaunted striker Colbey Northcutt (2-1) showed off some grappling skills in a first-round submission win over the debuting Courtney Martin (0-1).

Martin did her best to avoid the standup game by clinching and bringing the action to the floor early, but Northcutt was game from her back, chaining submission attempts together before locking in an armbar and extending the limb to earn a tap at the 2:28 mark of the first frame.
