Rajadamnern Stadium
Light Welterweight Title [63.5kg/140lb] (as of 2025-09-06)
Because it is difficult to find comprehensive muay thai results in English, these lists are always "under construction." Also, Thai competitors change their names when they switch their gym affiliations, and the names on this list may not be always accurate. If you have corrections or additional information, please send in (with specifying the source, of course).
* Bolded letters in the competitor's name, if any, indicate the surname/family name.
