Yokozuna Hakuho and ozeki Kisenosato showed convincing outings to preserve their perfect records on the sixth day of the New Year Grand Sumo Tournament on Friday, when three rank-and-filers lost ground with their first defeats.

Hakuho won his 18th bout in 19 meetings against Okinoumi (2-4), halting the No. 3 maegashira's charge with a firm tachiai before easily steering his counterpart out at Ryogoku Kokugikan.

Kisenosato kept up the pace with a composed win over Shodai (3-3), wrapping up the new sekiwake's left arm with his right before grappling him out for his fourth win in their fifth career meet.
