Two-sport ONE world champion Prajanchai PK Saenchai added another masterful performance to his decorated resume after successfully defending the strawweight Muay Thai world championship in the main event of ONE Fight Night 28 last Friday, Feb. 7.Showcasing the full extent of his mastery of 'The Art of Eight Limbs', Prajanchai knew the fight was over late in the fourth round when he opened a massive cut on Barboza's left eye.With a cheeky grin, he pointed at the gash, which the ringside physician immediately checked. Barboza was eventually ruled out from continuing, giving the win to the Thai hero via TKO due to a doctor's stoppage.Check out the entire sequence below, which ONE shared on Instagram: View this post on Instagram Instagram PostFans applauded the 30-year-old's showing in the comments section, writing:"Prajanchai is an absolute master! ⚔️🔥🩸""Man imagine if he was a bantamweight he would be the greatest MT fighter ever.""Absolute masterclass performance, his face looked perfectly clean at the end.""That was an easy fight for Prajanchai, he still looked completely fresh in the last round.
