Mongolian yokozuna Hakuho and ozeki Kisenosato maintained their perfect starts but yokozuna Kakuryu suffered his second defeat on Saturday, the seventh day of the Summer Grand Sumo Tournament.
Hakuho made a rare false start against his frequent victim Aoiyama (2-5), and was repeatedly put on his back foot by the No. 3 maegashira. But the Bulgarian inexplicably lost his balance trying to charge and floored himself for his 16th loss in 17 career bouts against the yokozuna.
Kisenosato was pushed toward the edge of the ring by giant Mongolian Ichinojo (3-4), but was calm and parried the No. 2 maegashira's attack before sending him out from behind.
