Mongolian yokozuna Hakuho came roaring back to gobble up ozeki Kotoshogiku on Thursday and moved two wins clear at the Kyushu Grand Sumo Tournament after yokozuna champion debutant Harumafuji was condemned to another upset defeat.

Stunned by Kotooshu the previous day, Hakuho locked up Kotoshogiku (7-5) after the charge and finished the ozeki off with a textbook underarm throw to move to 11-1 with three days left in the 15-day meet at Fukuoka Kokusai Center.

Hakuho, seeking his 23rd Emperor's Cup and first championship since March's Spring Basho, is two wins clear of fellow Mongolian Harumafuji, ozeki Kisenosato and three others.
