Yokozuna Musashimaru failed to make it a perfect 10 as he fell to his first defeat on Tuesday at the Kyushu Grand Sumo Tournament against veteran Daizen at Fukuoka Kokusai Center.
The Samoan-born grand champion had another untimely lapse of concentration, slipping up against the 36-year-old journeyman to fall back into a three-way tie for the lead on Day 10 of the 15-day tourney along with Takanonami and Tochiazuma.
Musashimaru (9-1) has yet to lift an Emperor's Cup this year, having been plagued by a series of upsets against unheralded opponents and yet again failed to deal with a mere rank-and-filer.
No. 6 maegashira Daizen (5-5), who was called back for one false start, was chomping at the bit at the face-off and slammed into the yokozuna the second time around, shoving him off balance before muscling him over the straw bales.
