3 Bouts That Could Steal The Show At ONE Friday Fights 137: Tawanchai Vs. Liu
ONE Championship closes out 2025 with ONE Friday Fights 137: Tawanchai vs. Liu on December 19, where elite strikers will seize their final chance to shine in the promotion’s year-ending showcase.
Streaming live in Asia primetime, this 12-bout card takes place inside Bangkok, Thailand’s legendary Lumpinee Stadium.
The headliner pits reigning ONE Featherweight Muay Thai World Champion Tawanchai PK Saenchai against surging upset specialist “Spirit Dragon” Liu Mengyang in a featherweight kickboxing showdown that will reshape the division’s landscape.
Beyond the main event, living legend Sam-A Gaiyanghadao faces Jaosuayai Sor Dechapan in a cross-generational strawweight Muay Thai battle, while strawweight kickboxing contenders “Fighting Rooster” Zhang Peimian and Thongpoon PK Saenchai promise fireworks.
While every bout on this loaded card carries explosive potential, here are three battles that could steal the spotlight at ONE Friday Fights 137.
#1 Kulabdam Vs. PTT
Excitement is guaranteed when heavy-handed crowd-pleasers “Left Meteorite” Kulabdam Sor Jor Piek Uthai and PTT Apichart Farm collide in the co-main event bantamweight Muay Thai clash.
For Kulabdam, a former Lumpinee Stadium Muay Thai World Champion, this represents another chance to reclaim his spot on the main roster.
The 27-year-old has 11 promotional wins, armed with devastating one-punch power in his iconic left hand. But his resolve was tested following back-to-back losses to former ONE Bantamweight Muay Thai World Champion Nong-O Hama and reigning king Nabil Anane.
Kulabdam responded by reaching peak form, mixing improved technical superiority with his signature power. He’s rattled off four straight wins over Suablack Tor Pran49, John Lineker, Ferzan Cicek, and Felipe “Demolition Man” Lobo.
Meanwhile, PTT brings 112 career victories into this crucial matchup. His ONE debut fell short with a narrow split-decision loss to Elies Abdelali at ONE Friday Fights 114. But the Thai aggressor evolved, showing a more cerebral approach against Alessio Malatesta to claim a split-decision victory at ONE Friday Fights 126.
Beating Kulabdam would represent PTT’s biggest career triumph. With both fighters refusing to retreat, expect an all-out war that ends inside the distance.
#2 Jo Nattawut Vs. Mohammad Siasarani
The featherweight Muay Thai battle between “Smokin” Jo Nattawut and Mohammad Siasarani could mark a veteran’s resurgence or signal a changing of the guard.
Nattawut has built his reputation blending traditional Muay Thai with boxing. The former ONE Featherweight Muay Thai World Title challenger has six wins in ONE, including a surgical performance against Luke “The Chef” Lessei at ONE Fight Night 17. Even in defeat, he’s tested elite competition, pushing Tawanchai to the limit twice.
But the 36-year-old Thai veteran faces questions after back-to-back first-round knockout losses to ONE Featherweight Kickboxing World Champion Superbon and top-five ranked Bampara Kouyate. Now, he aims to silence critics and prove he remains a legitimate threat in the promotion’s most stacked striking division.
Meanwhile, Siasarani burst onto the scene with a 4-0 start at ONE Friday Fights, announcing his arrival with a statement victory over legend Sitthichai “Killer Kid” Sitsongpeenong.
The 23-year-old Iranian hit a rough patch with two setbacks but responded with authority, rattling off three straight wins over Liu, Kaito Ono, and, most recently, Oskar “SugarGoku” Siegert at ONE Friday Fights 122.
He’s still on the hunt for the US$100,000 contract, and beating a respected mainstay like Nattawut could finally earn him the life-changing deal.
#3 Gingsanglek Vs. Suriyanlek
The flyweight Muay Thai showdown between Gingsanglek Wor Kumchamnarn and Suriyanlek Por Yenying features two fearless headhunters capable of stealing fight of the night honors.
Gingsanglek went under the radar after a 1-4 start against tough competition, but his last two fights showed his true potential with back-to-back highlight-reel finishes.
His wicked spinning back-fist knockout of Alexey Balyko at ONE Friday Fights 115 turned a lot of heads. Against Thant Zin at ONE Friday Fights 120, he dropped the durable fighter from Myanmar three times in one round, showcasing devastating finishing power and speed.
With momentum on his side, he’s hunting a third straight finish against an equally heavy-handed compatriot.
Meanwhile, Suriyanlek aims to build consistency and secure a roster spot. The 29-year-old has nine promotional wins, including spectacular finishes against Pompet PK Saenchai, Thant Zin, and Rambong Sor Therapat. However, he’s eager to bounce back from a close decision loss in his rematch against Decho Por Borirak at ONE Friday Fights 131.
Both fighters need a signature win to earn full-time contracts, which means neither will hold anything back on December 19.
