The first showdown in 29 years between undefeated wrestlers on the final day of a major sumo tournament wasn't even close.

Ozeki Harumafuji was leagues above rival Hakuho on Sunday, winning the Nagoya Grand Sumo Tournament and his third career Emperor's Cup, while denying the yokozuna his 23rd career title.

The Mongolian ozeki, whose last win came here last year, won with a perfect 15-0 record in a tournament for the first time. Hakuho had been the last to achieve the same feat as an ozeki at the 2007 summer basho.
