LONDON – Mansur Isaev of Russia won gold in the men’s -73kg final by beating the world champion, Japan’s Riki Nakaya.
Isaev, 25, was an outside favourite for the title after only finishing seventh at last year’s worlds in Paris.
The bronze medals were won by Nyam-Ochir Sainjargal of Mongolia and Ugo Legrand of France
Great Britain’s Daniel Williams lost his opening fight by ippon throw from the 2008 Olympic bronze medallist, Rasul Boqiev of Tajikistan.
Disappointed Williams, 23, left without speaking to reporters but his coach Luke Preston said: “Danny did everything right really and he just got caught when the guy got his chance, but that is judo.
“He was fighting an Olympic bronze medallist and just got caught that one second and it was all over,” Preston added.
Fourth seed Isaev overcame world number one Wang Ki-Chun of South Korea before seeing off Nakaya to secure gold.
Nakaya earlier had little trouble against Barbados’ Kyle Maxwell in the preliminary round, pinning him for the maximum ippon score (a technical knock-out).
