Yokozuna Hakuho plowed over ozeki Kotooshu and Harumafuji smacked the daylights out of fellow ozeki Kisenosato to remain undefeated Wednesday, putting space between them and their nearest challengers at the Nagoya Grand Sumo Tournament.

Hakuho, seeking his 23rd career title, and Harumafuji improved to 11-0 records, two wins ahead of ozeki Kotoshogiku and rank-and-filer Kaisei with four days remaining in Nagoya. Four wrestlers, including Kisenosato and ozeki Baruto, are 8-3.

In the day's finale, Hakuho got his left hand around for an outside grip on his opponent's mawashi while charging full throttle with his right arm over Kotooshu's (7-4) shoulder to win by frontal force out at Aichi Prefectural Gymnasium.
