Hakuho upended Russian youngster Wakanoho on Friday to preserve his unbeaten streak and stay one win clear of fellow Mongolian yokozuna Asashoryu after six days of action at the Summer Grand Sumo Tournament.

Wakanoho (2-4) never had a hope in the day's featured matchup as Hakuho quickly got a left-handed grip on his belt and twisted the No. 2 maegashira out in one swift move in a classy win at Ryogoku Kokugikan.

Hakuho shares the lead with Bulgarian Kotooshu.
