Grand Champion Tochinishiki Friday virtually clinched the Summer Grand Sumo Tournament title by scoring his 12th victory against one defeat as he overwhelmed third-ranking Sekiwake Matsunobori on the 13th day of the 15-day tourney at the Kokugikan Arena.
    Prospects of his capturing the crown loomed brighter as Grand Champion Kagamisato and Tokitsuyama who until Friday had two setbacks against them bowed to Wakanohana and Dewaminato respectively.
