Mongolian Asashoryu wrapped up his first Emperor's Cup as a yokozuna on Sunday after Musoyama slapped down Kaio on the final day of the Summer Grand Sumo Tournament.

In the penultimate bout at Ryogoku Kokugikan, Musoyama came charging out of the blocks to force Kaio back several steps before swatting his fellow ozeki down.

Kaio, who finished with an 11-4 record, needed to defeat Musoyama and then hope for a loss by Asashoryu in the final bout to force a playoff but couldn't establish control against a fired-up Musoyama.
