Yokozuna Hakuho suffered a stunning defeat on Friday to fall back into a three-way tie for the lead with an 11-2 record at the 15-day Nagoya Grand Sumo Tournament.

Hakuho had won his last three bouts against Kisenosato (9-4) and entered with a 35-10 career advantage over the ozeki. The yokozuna appeared to be in complete control of the bout, with his opponent back against the straw. But as he maneuvered to force the ozeki out, Hakuho was felled by a last-gasp armlock throw.

Instead of having clear sailing toward his 30th championship, Hakuho fell into a share of the lead at 11-2 with ozeki Kotoshogiku and No. 11 maegashira Takayasu. Some of the drama at Aichi Prefectural Gymnasium will be settled on Saturday, when Kotoshogiku takes on Takayasu.
