Rank-and-file grappler Tobizaru produced the biggest upset so far at the November Grand Sumo Tournament on Monday, handing overnight leader and title favorite Takakeisho his first loss.

The No. 4 maegashira, who became a sensation by contending for the title in his top-division debut in September, showed impressive strength and dexterity to outmaneuver the powerful ozeki in the final bout of Day 9 at Ryogoku Kokugikan.

The highest-ranked wrestler left in the field, ozeki Takakeisho opened with his customary pushing and thrusting attack, but Tobizaru held his ground despite a roughly 50-kg weight disadvantage.
