Yokozuna Hakuho swatted away Myogiryu to retain his share of the lead among six undefeated wrestlers on the fifth day of the Nagoya Grand Sumo Tournament on Thursday.

Each of the six wrestlers at sumo's second-highest rank of ozeki won, while three in the lower echelon of the elite makuuchi class stayed even with Hakuho and the ozeki duo Harumafuji and Baruto at 5-0 in the 15-day meet.

Hakuho, aiming for his 23rd career title and first in two meets, stunned Myogiryu with a right shoulder to the head at the face-off to send the komusubi off-balance, then smacked his opponent's head forward for a quick takedown.
