Context: why this rivalry mattered
Before August 2016, the Openweight Golden Belt had never been held by a fighter who was not born in Myanmar. The Myanmar Traditional Lethwei Federation had sanctioned international challengers before, but every previous title bout had ended with a Myanmar champion still wearing the belt. The mood inside Yangon's fight community when Dave Leduc — a Canadian cruiserweight with an MMA background — was matched with Tun Tun Min for the title was not unfriendly. It was simply quiet. The champion was thirty pounds heavier in fighting form, more experienced, and had not lost on Myanmar soil. Most observers expected a Tun Tun Min finish in the championship rounds.
What followed instead was a rivalry that defined modern Lethwei. Three bouts spanning sixteen months produced two Leduc wins, one Tun Tun Min win, and a body of footage that has been studied by every serious foreign fighter who has subsequently entered Myanmar.
Fight I — August 2016 — Draw
The first bout was held at Yangon's Theinbyu Stadium under traditional Golden Belt rules: five three-minute rounds, knockout-only, two-minute timeout permitted. Tun Tun Min came out throwing the body shots that had finished Cyrus Washington two years earlier — short left hooks to the liver, set up off a slip under Leduc's cross. Leduc absorbed two clean liver shots in the opening minute and did not visibly compromise.
The pivot point was round three. Leduc had been clinching every time Tun Tun Min closed the distance, and the champion had been working underhooks to neutralise Leduc's headbutt setups. In a clinch break with thirty seconds remaining in the round, Leduc snapped his forehead into Tun Tun Min's brow line and opened a cut. The cut was not deep enough to stop the fight, but it changed the next two rounds. Tun Tun Min became cautious in the clinch — protecting the cut — and Leduc owned the inside game from that point.
The result was a draw, but everyone in the building understood what had happened. The champion had not lost; the challenger had not been finished. Both corners knew there would be a rematch.
Fight II — December 2016 — Leduc by corner stoppage
Four months later, the rematch was held at the same venue under the same rules. Leduc walked into the ring as the slight underdog, but the betting markets had shifted from three-to-one to closer to even. The August fight had shown a path to victory.
Leduc opened the fight with the headbutt — feinting a punch entry, dropping his level, and snapping his forehead into the bridge of Tun Tun Min's nose in the opening exchange. Tun Tun Min's nose bled from the first minute. From that point, Leduc fought the entire bout around the cut. He was patient when the champion came forward; he closed the distance whenever Tun Tun Min tried to circle out; he reset the headbutt four more times across the next two rounds, opening the cut wider each time.
Round three ended with a clean cross from Leduc that landed on the nose. The cut had become a gash. Between rounds, the Tun Tun Min corner conferred with the ringside doctor for the second time. The doctor declined to stop it. Round four opened with Tun Tun Min visibly struggling to see clearly. A second cross landed in the same spot. The corner team finally signalled the stoppage with thirty seconds remaining in the fourth round.
Dave Leduc became the first non-Myanmar Openweight Golden Belt champion in the recorded history of Lethwei.
Fight III — 2017 — Leduc by spinning back elbow
The trilogy fight came under WLC rules rather than the MTLF Golden Belt format. Tun Tun Min had been training specifically for Leduc, and the early rounds were the most evenly contested of the three bouts. Both fighters knew the other's playbook by now. The clinch was neutral; the headbutt setups were defended; the body shots that had been Tun Tun Min's signature were checked behind elbows.
What broke the deadlock was a shot Leduc had drilled specifically for this fight. Late in round two, Tun Tun Min stepped in behind a jab. Leduc feinted a level change — selling the takedown defence response — and pivoted off his lead foot into a spinning back elbow. The point of the elbow caught Tun Tun Min flush on the temple. The challenger was unconscious before he hit the canvas.
The trilogy was over. Leduc had won two of three. The clip of the spinning elbow finish became the most-shared Lethwei knockout of the WLC era and was responsible for a measurable surge of foreign fighters seeking out Myanmar camps in the months that followed.
What the trilogy changed
Three things shifted permanently after the trilogy concluded. First, the Openweight Golden Belt was no longer treated as inherently a Myanmar fighter's belt. The myth of unbeatability on home soil had been broken, and the Federation had to reckon with a new generation of international challengers.
Second, the technical conversation around clinch defence in Lethwei changed. Tun Tun Min's previous body-shot game was the dominant model; after the trilogy, every Myanmar trainer was teaching headbutt defence as a primary curriculum item, not a secondary one. Leduc's success had revealed a hole in the Myanmar style that the country's coaches had to close.
Third — and most consequentially — the WLC's commercial model was vindicated. International audiences would tune in for genuine Myanmar-versus-foreign rivalries. Sponsors would underwrite them. Broadcasters would carry them. The trilogy paid for the next five years of WLC's growth.
