TOKYO (UPI) - Grand champion Tochinishiki set a postwar record of 24 straight wins Monday by easily defeating second ranking maegashira Tamahibiki for his ninth victory in the 15-day autumn sumo tournament here.
    Grand champion Wakanohana, who trailed Tochinishiki with a 7-1 record before Monday's bout, pulled down with his arms and quickly disposed of low-charging first-ranking maegashira Iwakaze.
    The 15th ranking maegashira, Atagoyama, matched Tochinishiki's clean slate in the tournament by pushing fiercely to beat fourth-ranking maegashira Naruyama for an upset. Naruyama had registered the tournament's biggest surprise thus far by defeating Wakanohana.
    Sekiwake Wakahaguro, who is a candidate for ozeki (champion), won his eighth bout against one loss as he drove third ranking maegashira Fujinishiki out of the ring.
    Wakahaguro and Wakanohana, both with 8-1 records, trail Tochinishiki and Atagoyama.
