Only just found out about Saensak Muangsurin today. Impressive life story and accomplishments. But its not easy to cross over from Muay Thai to Boxing. An experienced fighter like Tommy will poke holes in your strategy
The Thai guy was already coming of a loss to a journeyman and was moving up in weight. Some people say that on top of that he was half blind too and the "strategy” he used in this combat looked a lot like the one Kubrat Pulev tried on Klitchsko with similar results. Stand wide open for a straight right hand.
Half blind fighter coming off a loss to a journey man is one way to characterise a fighter. I only heard of him cos he won a world title in his 3rd fight. And he was able to defend it too
I am a Thai person who is looked after and accepted. It's a pity that Thai boxing at that time Not universally open, Saensak is a good muay thai fighter. But he was not trained as a boxer like Thomas Hearns was.
