Ozeki Goeido seized a share of the Autumn Grand Sumo Tournament lead on Friday, when he improved to 5-1 by knocking off previously unbeaten Onosho.
The 21-year-old Onosho, fighting as a No. 3 maegashira in just his third tournament in the elite makuuchi division, showed his inexperience as the 31-year-old ozeki led him into a trap on the sixth day of the 15-day tournament at Tokyo's Ryogoku Kokugikan.
Goeido, who had dodged several opponents' opening charges as he searches for the eight wins he needs to maintain his rank for November's tournament, moved forward as if he were trying a conventional charge, but allowed the youngster to push him backward.
