Kisenosato won the 59th edition of sumo's longest-running top-flight rivalry in the blink of an eye Monday as he maintained his perfect record on the ninth day of the Spring Grand Sumo Tournament.

Kisenosato, in sole possession of the lead at the turning point for the first time in his career, exploited fellow ozeki Kotoshogiku's penchant for charging low on the tachiai.

Kotoshogiku (7-2) wasn't quick enough to surprise his opponent. Instead of catching Kisenosato off balance, he charged into an ambush and was easily yanked to the surface in less than a second.
