Another surprise gold medal winner was Fabio Basile in the men’s 66 kg class. He was ranked 29th on the IJF list, and his best result prior to the Olympics was a bronze medal at the 2016 European Championships. On his way to the Rio final, he defeated three opponents by Ippon (full point), including second ranked Davaadorjiin Tömörkhüleg from Mongolia, the 2014 Asian Games gold medalist. He also beat Slovenia’s Adrian Gomboc. The Slovenian was the only opponent lower than Basile in the ranking list and in the semi-final he resisted Basile for the complete five minutes but lost by two Shidos (penalties) for non-combativity. In the final Basile faced the top ranked reigning World Champion An Ba-Ul of Korea. Basile surprised him with a Seoi-otoshi (back-drop) scoring an Ippon just 1:24 min into the bout.
Bronze medals went to Rishod Sobirov of Uzbekistan and Masashi Ebinuma of Japan, both previous World Champions. Both were defeated by An in the quarter-finals and semi-finals respectively of the elimination round.
