Saenchai PKSaenchaimuaythaigym

Suphachai Saepong (; born July 30, 1980), known professionally as Saenchai (), is a Thai professional Muay Thai fighter and former professional boxer. He is a former six-time Lumpinee Stadium champion across four divisions as well as the 1999 and 2008 Sports Writers Association of Thailand Fighter of the Year. Nicknamed the "Ultimate Boxer from Sarakham", he is often regarded as one of the greatest and most talented fighters in the history of Muay Thai.

Saenchai would often give up weight to find worthy opponents in Thailand, and from 2003 to 2014 only lost two times in Thailand when the weights were equal, with all other losses happening when he was forced to have a weight disadvantage to make the fights more equal. Since 2010 he has fought 88 times in 15 countries and is perhaps the most active international fighter. He is known for his excellent head movement, defensive footwork, unconventional kicks, and jumping attacks. His speed, athleticism, and the large variety in his unorthodox arsenal made him an exceptionally difficult opponent to prepare for. Incorporating Muay Boran style kicks and manoeuvres, he is known as a showman. He retired from serious competition in Thailand in 2014 and now solely competes in showcase fights around the world against foreign, usually bigger opponents. Upon retiring from competition on the Thai circuit he was still able to make 130 pounds, with his final fight being forced to make 129 pounds.
