Updated Thursday, May 15, 2008 0:00 am TWN, AP Sumo grand champions continue to dominateHakuho toppled fellow Mongolian Kyokutenho with a powerful overarm throw that sent the No. 2 maegashira tumbling onto the ring. The yokozuna improves to a perfect 4-0 in his quest for his seventh title victory, and looks to avenge a final-day loss in March to archrival Asashoryu at the Spring Grand Sumo Tournament. Kyokutenho fell to 1-3. Russia’s Wakanoho had a shot at pulling off another upset against Asashoryu, but the Mongolian executed an aggressive, well-timed armlock throw at the edge of the ring against the No. 2 maegashira. Despite a shocking opening-day loss, the confident Asashoryu improved to 3-1 in his march toward a 23rd Emperor’s Cup. A victory would move him into fourth place on the all-time title list. Kotooshu, who must post a winning record at the 15-day meet to maintain his ozeki status, gained more momentum with a victory over winless Kokkai of Georgia. With a frontal push down from the left, the Bulgarian rammed the No. 1 maegashira into the clay. | Other Breaking News Most Read |
