Sekiwake Tochiozan upset the form chart by dealing rampant ozeki Terunofuji his first defeat at the Autumn Grand Sumo Tournament on Thursday.
Tochiozan, who entered the day having lost all five of his career matches to the larger 23-year-old Mongolian, was put on the defensive from the get-go but managed to keep Terunofuji off his belt. When the ozeki shifted his weight for another attempt at a belt hold, Tochiozan (7-5) struck, spinning his opponent around and forcing him out.
The defeat at Tokyo's Ryogoku Kokugikan kept Terunofuji from expanding his lead after his closest pursuer, maegashira Ikioi, suffered his second loss.
