Profile

Sangtiennoi Sor.Rungroj was pressure without apology.

Where other fighters controlled fights with distance or timing, Sangtiennoi closed space and stayed there. His nickname, The Deadly Kisser, came from the way he fought chest-to-chest — elbows, knees, head pressure — forcing opponents into suffocating exchanges they couldn’t escape.

He was one of the most popular fighters of his era, earning purses exceeding 200,000 baht at a time when only true stadium stars commanded that money. Fans didn’t come to watch him “win clean.” They came to watch him break rhythm and impose pain.

Fighting Style

Sangtiennoi was a pure Muay Bouk — but intelligent, not reckless.

Key traits:

  • Constant forward pressure

  • Clinch-heavy aggression

  • Short-range elbows and knees

  • Physical dominance in exchanges

  • Willingness to absorb damage to advance

Unlike volume punchers or kick-heavy fighters, Sangtiennoi’s goal was attrition. He crowded opponents, disrupted balance, and turned fights into physical contests where composure eroded round by round.

Stadium Career & Elite Opposition

Sangtiennoi competed at the very top of the sport during one of its deepest periods.

Titles:

World Muay Thai Council

  • 1988 WMC World -65 kg Champion

Lumpinee Stadium

  • 1997 Lumpinee Stadium Lightweight (135 lbs) Champion (1 defense)

Rajadamnern Stadium

  • 1989 Rajadamnern Stadium Super Featherweight (130 lbs) Champion

Notable opponents:

  • Ramon Dekkers

  • Dany Bill

  • Namkabuan Nongkeepahuyuth

  • Samkor Kiatmontep

  • Chamuakpetch Hapalang

  • Orono Por Muang Ubon

His rivalry with Ramon Dekkers is particularly telling: two pressure fighters from different worlds meeting in fights defined by grit rather than finesse.

International Influence & Teaching

Sangtiennoi was not just a fighter — he was a transmitter of Muay Thai.

He was a primary Thai-based training partner and mentor to John Wayne Parr, helping shape one of the most influential Western Muay Thai careers ever. His style translated brutally well overseas, where clinch pressure and elbows shocked non-Thai audiences.

After shoulder injuries forced his retirement in 2000, Sangtiennoi opened a gym in Pathum Thani, where he continued training fighters until his death.

Later Life & Passing

Sangtiennoi struggled with injuries and personal challenges later in life. He died in 2021 at the age of 54.

Within the Muay Thai community, his passing was met with deep grief — not just for the fighter he was, but for the teacher and presence he had become to fighters around the world.

Legacy

Sangtiennoi Sor.Rungroj is remembered as:

  • One of the most relentless pressure fighters of his era

  • A defining Muay Bouk archetype

  • A bridge between Thai stadium fighting and Western Muay Thai

  • A fighter whose presence changed the feel of a fight

He didn’t control space.
He took it.
