He is definitely back. Six years after his last participation in the World Judo Championships, Teddy Riner qualified brilliantly for the semi-finals of the Doha Worlds on Saturday. The Guadeloupean eliminated the Japanese Tatsuru Saito, yet vice-world champion, in a sort of final before the unbreathable hour, concluded with the golden score. With just over a year to go until the Olympics, Riner is in contention for an eleventh world heavyweight title.
