Yokozuna Hakuho won a tough match against Egyptian giant killer Osunaarashi on Sunday to maintain his share of the lead at the 15-day Nagoya Grand Sumo Tournament.

Hakuho got all he bargained for from Osunaarashi, who had already defeated both yokozuna opponents he had faced at Aichi Prefectural Gymnasium.

Ozeki Kotoshigiku and No. 11 maegashira Takayasu are also unbeaten. Yokozuna Kakuryu was the sole wrestler with just a single loss after eight days.
