Ozeki Harumafuji knocked the daylights out of Takayasu to remained undefeated Tuesday, but yokozuna Hakuho took a spill for his first loss at the hands of Tochiozan on the 10th day of the Autumn Grand Sumo Tournament.

Harumafuji, who is making his third bid at promotion to sumo's highest rank of yokozuna after a 15-0 tour de force at the Nagoya Basho in July, improved to 10-0 with five days remaining at Ryogoku Kokugikan.

Hakuho's defeat, meanwhile, was a major blow to the lone yokozuna who is seeking his 23rd career title.
