Biography and career

Yothin has modeled his career on that of a knee fighter from the same gym Petchboonchu FA Group under the same teacher Kru Diesel.
From March 2016 to March 2017 Yothin had 8 victories and only 1 defeat which led him to be on the shortlist for the Thailand Sports Writers Fighter of the Year Award. This extended winning streak in the Rajadamnern Stadium got Yothin to be ranked #1 in the stadium rankings in his division.
After becoming the 2024 WBC Muay Thai International Featherweight Champion, Yothin became the 2024 Rajadamnern Stadium Featherweight (126 lbs) Champion. He successfully defended his Rajadamnern title in May 2025.
