With a record-extending 37th career title already in the bag, Hakuho put the icing on the cake on Sunday, defeating fellow Mongolian yokozuna Kakuryu to finish with a spotless 15-0 record at the Summer Grand Sumo Tournament.

Hakuho, who clinched his second straight Emperor's Cup on Saturday, saved arguably his best performance until last in an epic tussle, countering at the edge of the ring to turn the tables on Kakuryu (11-4) with a utchari backward pivot throw.

Hakuho extended his unbeaten streak to 29 matches, having not lost since the first day of the Spring Basho in Osaka in March.
