Yokozuna Hakuho relinquished his perfect record Friday in a shock loss to second-ranked maegashira Abi on Day 6 of the Summer Grand Sumo Tournament.

With Hakuho apparently looking for a belt hold, the 24-year-old Abi drove his head and shoulder into the all-time championship record-holder's chest, driving him backward out of the ring in just 2.9 seconds.

"That was good sumo," Hakuho said of his opponent, who has posted 10-5 records in both of his career makuuchi division tournaments.
