OSAKA — Things just got really lonely at the top.

After perennial troublemaker Asashoryu quit sumo following allegations he attacked a man outside a Tokyo nightspot, Hakuho remains as the sole yokozuna and hot favorite to cart home the Emperor's Cup at the Spring Grand Sumo Tournament getting under way on Sunday.

Alas, sumo without Asashoryu, who took time out from his reputed street brawling to also win the New Year's meet, could be a lot like watching a one-man show — predictable and lacking the unique pizzazz that the Mongolian firebrand brought to the sport.
