TOKYO( Kyodo)--Shohei Ono went back-to-back as Olympic men's 73-kilogram judo champion at the Tokyo Games on Monday following a golden-score victory over Georgia's Lasha Shavdatuashvili.... The 29-year-old Ono had looked unbeatable on the way to the gold-medal match at Nippon Budokan, but had to dig deep against Shavdatuashvili to defend the title he won five years ago in Rio de Janeiro.... A third would have handed the bout to Shavdatuashvili, winner of 66-kg gold at the 2012 London Games....
