East Ilsley trainer Hughie Morrison was at a loss to explain Sakhee's Secret's flop behind shock 33-1 winner Kingsgate Native in the Golden Jubilee Stakes at Royal Ascot.
Sent off the 5-1 third favourite for the Group 1 sprint, last year's July Cup winner trailed in last of the 17-strong field in front of a record Saturday crowd of 70,675.
Morrison, who saddled Supaseus to take Friday's Wolferton Stakes, said: "He was never going on the ground and we will take him home and hope to find something, he was beaten to early for that to be his running.
"The only time he has run badly before was on fast ground that had been softened by rain like this."
Jockey Steve Drowne was also mystified by his mount's poor run.
"He lost a front shoe, but I was the first beaten. The ground's not loose enough to say he would run that badly. It just wasn't his running."
Meanwhile, trainer John Best was thrilled by Kingsgate Native's victory.
Seb Sanders powered the three-year-old home by a length and a quarter from War Artist, with Sir Gerry third.
And Best, who had sent out Flashmans Papers to spring a 100-1 upset in the Windsor Castle Stakes on Tuesday, celebrated wildly.
"I do get very excited when I have winners - it means so much - and to have winners here is the ultimate," he said.
