“The Flash” neutralized one of the division’s most dangerous wrestlers to earn a place on ONE Championship’s primary roster and move one step closer to a strawweight title opportunity.
South Korea’s Seung Chul Lee delivered the biggest victory of his professional career on Friday night, defeating South Africa’s Bokang Masunyane by unanimous decision at ONE Fight Night 45: Lessei vs. Rabah on Prime Video.
Competing inside the legendary Lumpinee Stadium in Bangkok, Thailand, Lee entered the bout as a slight betting favorite but faced one of the toughest stylistic tests in the ONE Championship strawweight division. After three disciplined rounds, all three judges awarded the fight to the South Korean, improving his standing within the promotion and officially earning him a place on ONE Championship’s primary roster.
The victory also positions Lee as a legitimate contender in the strawweight division, bringing him closer to a potential showdown with reigning champion Joshua Pacio.
Lee Solves the Wrestling Puzzle
Few fighters have managed to consistently frustrate Bokang Masunyane’s relentless wrestling attack.
Known for explosive level changes, heavy overhand punches, and relentless pressure, Masunyane entered the contest with an 11-3 professional record and a reputation as one of the division’s most physically demanding opponents.
Rather than engaging in prolonged grappling exchanges, Seung Chul Lee built his game around movement and distance management.
From the opening round, “The Flash” stayed just outside Masunyane’s preferred range, forcing the South African to repeatedly overextend as he attempted to close the distance. Lee’s lateral movement prevented Masunyane from establishing clean wrestling entries, eliminating the momentum that typically fuels his offense.
Every failed shot forced Masunyane to reset, allowing Lee to dictate the tempo of the fight.
Precision Over Power
While Masunyane searched for explosive moments, Seung Chul Lee consistently found success through timing.
The South Korean repeatedly intercepted his opponent with clean counter punches whenever Masunyane rushed forward behind looping combinations or takedown attempts.
Instead of chasing a knockout, Lee remained patient, choosing accuracy over volume.
His disciplined striking repeatedly beat Masunyane to the target, frustrating the South African throughout all three rounds.
Although Masunyane continued pressing forward, he struggled to land meaningful offense against Lee’s superior range management and footwork.
By the final horn, Lee had clearly produced the cleaner and more effective striking performance.
Takedown Defense Passes a Major Test
Perhaps the most significant takeaway from the victory was Seung Chul Lee’s defensive wrestling.
Heading into the matchup, many viewed Masunyane’s elite wrestling pedigree as the biggest obstacle standing between Lee and a permanent spot on the ONE Championship roster.
Instead, Lee answered those questions emphatically.
His takedown defense consistently shut down Masunyane’s attempts to establish dominant top control, forcing extended striking exchanges where the South Korean held a clear technical advantage.
The performance demonstrated that Seung Chul Lee’s defensive grappling can withstand the pressure of one of the division’s strongest wrestlers—a valuable statement as he climbs toward title contention.
Masunyane’s physical explosiveness remained dangerous throughout the contest, but his reach disadvantage and inability to consistently close distance limited his effectiveness.
The defeat drops the South African veteran to 11-4 as a professional.
What It Means
Friday’s victory could prove to be a career-defining moment for Seung Chul Lee.
Beyond securing a unanimous decision over one of the strawweight division’s most respected wrestlers, the win officially cements his place on ONE Championship’s primary roster and significantly elevates his standing within the promotion.
Just as importantly, Lee showcased a complete performance against a stylistic nightmare. His striking remained composed under pressure, his footwork consistently disrupted Masunyane’s game plan, and his takedown defense answered one of the few remaining questions surrounding his overall skill set.
If “The Flash” continues to produce performances like this against the division’s elite, a matchup with ONE Strawweight MMA World Champion Joshua Pacio may no longer be a distant goal—it could be the next major step in one of Korean MMA’s most promising careers.
For Korean MMA fans, Seung Chul Lee’s victory represents more than another win on the international stage. It is another reminder that South Korea continues to produce well-rounded athletes capable of competing with the world’s best across every aspect of mixed martial arts.
