Harumafuji kept his eyes firmly fixed on the prize at the Autumn Grand Sumo Tournament on Thursday, a routine win over Goeido keeping the rugged Mongolian ozeki on course for back-to-back titles and promotion to sumo's ultimate rank of yokozuna.

Harumafuji, who is making his third attempt at yokozuna after going unbeaten en route to the championship in the Nagoya Basho in July, improved to 12-0 and maintained his slender lead over Mongolian yokozuna Hakuho, who is alone in second place at 11-1 with three days remaining in the 15-day Autumn Grand Sumo Tournament.

Ozeki pair Kisenosato and Kakuryu are a further win back with veteran Kyokutenho and maegashira Takayasu both at 10-2.
