Underdog Annenyama, conqueror of Grand Champion Chiyonoyama Thursday, rose to great heights for the second successive day Friday as he grappled hard and fast with second-ranking Ozeki Mitsuneyama to force the 322 pounder to hit the dirt to highlight the sixth day of the Summer Grand Sumo Tournament at Kokugikan. It was Mitsuneyama's third defeat in six times out.
    At the close of the sixth day of the tourney, Yokozunas Kagamisato and Tochinishiki still retained unblemished records of 6-0 by dumping Shimanishiki and Futatsuryu respectively.
