On September 13, 2017, at the age of 32, he challenged the WBO world champion, Kosei Tanaka, at Edion Arena. Tanaka was a huge favorite going into the fight, but Palangpol would prove to be Tanaka's toughest challenger so far, dropping the defending champion once in the first round and trading back-and-forth combinations for the rest of the bout. After a thrilling fight, Tanaka would finally gain the upper hand in round 9, as he knocked down Palangpol and continued to land big combinations as the challenger struggled to connect. Eventually, the referee stepped in and stopped the fight at 1:52 in round 9. Tanaka was severely cut under his eyes, and was consequently sidelined after the fight. After the bout, Nattadej "Boat" Wachirarattanawong, his assistant manager, said that at his age he would continue competing in both Muay Thai and professional boxing.
