Yokozuna Musashimaru clinched his 11th title in the Natsu Basho on the 14th day, only to lose to ozeki Kaio on the final day, to finish with a 13-2 record.
Musashimaru had remained undefeated until the 13th day, when he lost to ozeki Chiyotaikai. If he had gone all the way with a 15-0 record, or zensho yusho, Musashimaru would have become the first rikishi to take the Makunouchi Championship with a perfect record since September 1996, when Takanohana did so.
Musashimaru seems to have a propensity to overly relax in the last few days, especially on the final day. Maru actually has already achieved zensho yusho, back in July 1994, when he won his first championship at ozeki, the only foreign-born rikishi to date who has done so.
