Front-runners Hakuho and Terunofuji maintained their perfect records after 11 days at the Nagoya Grand Sumo Tournament on Wednesday, opening a three-win gap over their closest pursuers in the title race.

Both Hakuho and Terunofuji faced tricky opponents but came away unscathed. Yokozuna Hakuho beat debutant komusubi Wakatakakage, while resurgent ozeki Terunofuji brushed aside sekiwake and two-time Emperor's Cup winner Mitakeumi at Dolphins Arena.

Having missed all or part of the past six meets, 36-year-old Hakuho continued to dispel talk of retirement, powering past the nimble Wakatakakage (3-8), who is making his debut here at the three sanyaku ranks below yokozuna.
