Hakuho put on another sumo clinic on Sunday to stay unbeaten and tied for the lead with fellow Mongolian grand champion Harumafuji after eight days of action at the Summer Grand Sumo Tournament.
Hakuho oozed class in his bout against struggling Kotoshogiku (1-7) at Ryogoku Kokugikan, quickly taking the sekiwake down with a textbook pulling overarm throw to move to 8-0 at the 15-day meet in Tokyo.
Kisenosato survived a scare and squeezed out his second win of the Summer Grand Sumo Tournament on Tuesday, while fellow yokozuna Hakuho and Harumafuji kept their perfect record intact after three days.
Still nursing the left upper arm and chest injury he suffered at the Spring tourney in March, Kisenosato was on the back foot throughout against a spirited No. 1 maegashira Chiyonokuni (1-2), who handed yokozuna Kakuryu his second defeat a day earlier.
Yokozuna Harumafuji sent Kisenosato tumbling down the ring to his first thrashing as yokozuna - and left him with a damage - on Friday, the thirteenth day of the Spring Grand Sumo Tournament, where ozeki Terunofuji now imparts the lead likewise to one defeat.
Harumafuji (10-3) left Kisenosato reeling with a solid low charge and the Mongolian didn't let his adversary move out, pounding the debutant yokozuna out and off the ring in the day's last bout.
