Yokozuna Harumafuji was sent to a shock defeat at the hands of Myogiryu on the second day of the Summer Grand Sumo Tournament on Monday.
Hakuho beat the daylights out of Aminishiki to stay on course for his 25th career title after winning the spring tourney with an unblemished 15-0 mark.
Harumafuji stumbled with another 9-6 meltdown in March, the same mark he posted in his yokozuna debut last November. But the fiery Mongolian has also gone 15-0 to win three of the previous five tournaments.
