BEIJING (AP) French teenage world champion Teddy Riner lost a close overtime bout in the quarterfinals to end his chances at an Olympic judo gold in the men's over 100-kilogram division Friday.
Riner, a judo sensation since he took the world championship last year at age 18, started off cautiously, winning his opening bout on points. He blasted through his second match, flipping Kazakhstan's Yeldos Ikhsangaliyev shortly after their bout began.
But he slowed down again in the quarters, going into the final minute at 1-1 with Uzbekistan's Abdullo Tangriev. The two then went into overtime, and again neither was able to find an opening.
Tangriev was declared the winner on a penalty against Riner for passivity just before time ran out.
Russia's Tamerian Tmenov - who lost to Riner in the world championship final - took an early lead in his first bout over Athens bronze medalist Dennis van der Geest, but the match never turned into much of a rivalry because the Dutchman hurt his right arm and spent most of the second half on the defensive.
Tmenov then scored two waza ari on China's Pan Song to make the quarterfinal against Japan's Satoshi Ishii, who is making his Olympic debut after coming out of the shadow of longtime champion Kosei Inoue.
Ishii won that bout on a yuko point, sending Tmenov into the loser's bracket. Ishii meets Georgia's Gujejiani and Tangriev fights Cuba's Oscar Brayson.
In the women's 78-kg, China's heavyweight judo champion, Tong Wen, breezed into the semifinals.
A three-time world champion, she flipped her first opponent and pinned her second and third to make the semifinal, where she will fight Cuba's Idalys Ortiz.
Athens gold medalist Maki Tsukada fell behind to France's Anne-Sophie Mondiere, who is ranked second in the world, on a koka point, but came back with an ippon to clear her first fight. She pinned Mexico's Vanessa Zambotti for her semifinal berth.
In the semifinals, she will meet Slovenia's Lucija Polavder, who is ranked fifth in the world.
