TOKYO (UPI) - Ozeki (champion) Kotogahama, always one of the steadiest contestants, suffered his fourth straight defeat Wednesday in the 15-day sumo tournament.
    The 31-year-old Kotogahama was sluggish, failed to attain a hold and was pushed out of the ring by 22-year-old third-ranking maegashira Fujinishiki.
    Grand champions Tochinishiki and Wakanohana proved too strong for their opponents and continued their winning streaks.
    Tochinishiki downed former ozeki Matsunobori while Wakanohana drove out sixth-ranking maegashira Kitanonada without trouble.
    Komusubi Kitabayama defeated second-ranking maegashira Tamahibiki in the day's hardest fought bout.
    Up-and-coming third-ranking maegashira Kashiwado stopped komusubi Annenyama's winning streak in a hard-fought bout. Kashiwado checked Annenyama's drive and throws arid forced him out of the ring.
