Yokozuna Musashimaru crashed to a first defeat Wednesday while ozeki Tochiazuma was also tripped up for his first loss on a day of upsets at the Nagoya Grand Sumo Tournament.

The day's final bout started off typically enough with the Samoa-born grand champion well in control as he wrapped his burly arms around top-ranked maegashira Tochinonada for leverage at Aichi Prefectural Gymnasium.

But Tochinonada (3-1) got his left hand on the yokozuna's "mawashi" belt at the last second as he tip-toed on the edge of the ring and twisted Musashimaru down for his first loss of the 15-day meet.
