Mongolian yokozuna Hakuho put on another sumo clinic against Russian grappler Aran on Friday as the leading pack narrowed down to two on the sixth day of action at the New Year Grand Sumo Tournament.

Hakuho oozed class in the day's finale, pulling free from a bear hug to methodically work Aran (3-3) toward the straw bales and out with a routine shove.

Hakuho, who is seeking his sixth straight Emperor's Cup and 18th overall title here, and rank-and-filer Tochinonada led the way at 6-0 on a day when ozeki pair Kaio and Harumafuji both tasted upset defeats.
