One faulty start from an overzealous Harumafuji was all Aoiyama needed to send the yokozuna to his second defeat on the fourth day of the Autumn Grand Sumo Tournament on Wednesday.

In stark contrast, fellow yokozuna Hakuho, aiming for his 27th career Emperor's Cup, ripped down another would-be opponent in the form of Okinoumi (2-2) in the day's penultimate bout at Ryogoku Kokugikan. Hakuho shares the early lead at 4-0 with ozeki Kotooshu and rank-and-filers Yoshikaze and Kyokutenho.

Things went drastically wrong for Harumafuji as he made one false start in the day's finale against the Bulgarian goliath.
