Mongolian yokozuna Hakuho and ozeki Kisenosato maintained their perfect records, but ozeki Goeido slipped to his first defeat on Friday, the sixth day of the Summer Grand Sumo Tournament.
Hakuho improved to 8-1 in his career against second-ranked maegashira Ichinojo (3-3) but was made to sweat, dragging his compatriot toward him with a weak pull down attempt but surrendered a right underarm belt hold in the process. Ichinojo, however, couldn't capitalize as Hakuho regained his position in the penultimate bout at Ryogoku Kokugikan. Hakuho then thrust down his giant opponent using his left arm.
Kisenosato also labored to win after allowing a firm left underarm grip to komusubi Kaisei (1-5), but managed to recover with an overarm belt hold in each hand. The ozeki then grappled the Brazilian out to end the day's longest match at 1 minute, 28 seconds, and improve to 8-0 against Kaisei.
