Mongolian yokozuna Asashoryu gunned down Miyabiyama to stay hot on the trail of yokozuna rival Hakuho at 4-1 at the Summer Grand Sumo Tournament on Thursday.
Asashoryu soaked up a flurry of thrusts to the face but was never in danger in the day's finale at Ryogoku Kokugikan, disposing of the former ozeki (1-4) with a pair of meaty shoves at the ring's edge.
Hakuho stayed one win clear of Asashoryu while Bulgarian ozeki Kotooshu and No. 5 maegashira Toyonoshima are the other early pacesetters with five wins at the 15-day meet in Tokyo.
