Hakuho underlined his championship credentials by toppling Miyabiyama, and Asashoryu also bared his teeth as both yokozuna made it two wins out of two at the Autumn Grand Sumo Tournament on Monday.
Looking to join former yokozuna Futabayama with a 12th Emperor's Cup, Hakuho showed why he has lost only three bouts in regulation this year with an assured performance at Tokyo's Ryogoku Kokugikan.
The 24-year-old shrugged off Miyabiyama's (0-2) attack and launched a devastating assault that sent the No. 1 maegashira tumbling backward into the front row of ringside cushions.
