Grand champion Asashoryu posted an unorthodox win over fellow Mongolian Kyokutenho on Friday to move into sole possession of the lead while ozeki Tochiazuma notched his fifth straight victory at the New Year Grand Sumo Tournament.

In the final bout at Ryogoku Kokugikan, Asashoryu, who has lost to Kyokutenho only once in the last six tournaments, was locked in a stalemate with his compatriot when the No. 3 maegashira inexplicably touched the dirt surface with his knee.

Asashoryu improved to 6-0 while Kyokutenho fell to 2-4.
