After making a stuttering start to his campaign by scrapping past Belarusian fighter Pavel Kastramin with a split decision in the preliminary round, Sailom, one of four Thai fighters remaining at the Games, got into his stride against Chamov before running out as deserved winner.
Given the result, the 30-year-old, who has usually failed to shine on big stages, booked his quarterfinal spot against France’s Souleymane Cissokho, who clinched two successive unanimous wins in a row on his way to the last eight.
