Ozeki Chiyotaikai was sent reeling to his first defeat at the hands of Dejima, but got a lucky break to remain the sole leader when Mongolian yokozuna Hakuho fell to a shock second loss against compatriot Ama at the Kyushu Grand Sumo Tournament on Sunday.
Chiyotaikai slipped to 7-1 while Hakuho fell into a group of seven wrestlers one off the pace with 6-2 records as the 15-day meet enters the final week.
Chiyotaikai, normally known for his rapid-fire thrusting attack, never got his arms rolling as Dejima beat him out of the crouch at Fukuoka Kokusai Center.
