ONE strawweight Muay Thai and Kickboxing world champion Prajanchai PK Saenchai believes his teammate showed uncharacteristic vulnerability in his recent high-profile setback.Kongthoranee Sor Sommai suffered a unanimous decision defeat to former ONE bantamweight Muay Thai world champion Nong-O Hama in their flyweight rematch at ONE Fight Night 31 this past May.The loss marked a significant setback for the No.4-ranked divisional contender in his quest for world championship gold.The defeat, however, came as a surprise given Kongthoranee's impressive track record and tactical brilliance. He had, after all, beaten Nong-O by split decision in their first encounter just months before his setback in their sequel.Prajanchai served as a cornerman during the rematch and witnessed firsthand what he believed prevented his teammate from delivering his best performance."Kongthoranee is a very hardworking and determined fighter. He's very skilled and smart. But on that day when he fought with Nong-O, he seemed a bit nervous," the PK Saenchai Muaythaigym affiliate told ONE Championship.
