Mongolian yokozuna Harumafuji on Friday took a major step toward his eighth career title by seizing sole possession of the lead with two days remaining at the Nagoya Grand Sumo Tournament.

Harumafuji overpowered promotion-chasing ozeki and overnight co-leader Kisenosato in the day's finale at Aichi Prefectural Gymnasium to score his 11th win at the 15-day basho.

Kisenosato, Mongolian yokozuna Hakuho and rank-and-filer Takanoiwa share second at 10-3.
