Mongolian grand champion Asashoryu never even flinched as he left another hapless victim in his wake to maintain a spotless record at the Autumn Grand Sumo Tournament on Saturday.

The pugnacious yokozuna marched out rank-and-filer Kotoryu in a business-as-usual final bout to stay at 7-0 at Tokyo's Ryogoku Kokugikan, while ozeki Kaio and rank-and-filer Kakizoe stayed within touching distance one off the pace at the 15-day meet.

Asashoryu, who is seeking his fourth Emperor's Cup and only his second as grand champion, wrapped up the third-ranked maegashira immediately after the face-off with an overpowering frontal assault.
