BEIJING, Nov. 15 (Xinhua) -- Alim Gadanov of Russia made a coup here on Thursday, overrunning Olympic gold medallist Masato Uchishiba of Japan in the men's under 66kg final to crown at the two-day Olympic test event -- the 2007 Beijing Judo Open.

The Russian, who's barely known on the world stage of judo before winning the Super World Cup in Rotterdam in September, narrowly beat his established Japanese rival with a yuko after making the final on an even tinier edge of a koka over Brazil's Leandro Cunha.

Uchishiba, 29, who won the Olympic gold medal three years ago in the same category in Athens, had been unbeaten in his previous three matches but was found nail-biting in the final.

The bronze medals went to Chinese Liu Changchun, who lost to Uchishiba in Group B final, and the other group's repechage winnerJordan Amoros from France, both winning the third-place match with ippon.
