Grand champion Asashoryu overpowered Chiyotaikai on Sunday to close out the New Year Grand Sumo Tournament in Tokyo with a perfect 15-0 record.

Asashoryu, who wrapped up his 10th Emperor's Cup on Friday, knocked Chiyotaikai off balance shortly after the faceoff and then waltzed the veteran wrestler out from behind to remain undefeated. Chiyotaikai finished with an 8-7 record, good enough to hold on to his ozeki status.

With his 10th career title, Mongolian Asashoryu joined sumo greats Kitanoumi, Chiyonofuji and Taiho as the only wrestlers to win the New Year meet for three straight years since the establishment of the six-tournament system in 1958.
