Yokozuna Asashoryu dodged a bullet against Russian youngster Wakanoho while rival yokozuna Hakuho gave Kyokutenho a royal tanning to remain undefeated on the fourth day of the Summer Grand Sumo Tournament on Wednesday.

Asashoryu let Wakanoho inside for a right-handed underarm grip off the charge but tossed his 19-year-old opponent over the edge with a well-timed armlock throw to improve to 3-1, one behind his main rival at Ryogoku Kokugikan.

In the day's final bout, Kyokutenho never had a chance after Hakuho got his preferred "migi-yotsu" grappling position and slammed his opponent to the dohyo surface with a powerful overarm throw. Kyokutenho slipped to 1-3.
