Ouija Board, ridden by Kieren Fallon, has stormed to a win at US racing's blue riband event, the Breeders' Cup.
Ouija Board cruised to a comfortable win at Lone Star Park
The Ed Dunlop-trained filly won the Filly & Mare Turf at Lone Star Park in Texas, seeing off Film Maker by a length and a half.
Fallon's rival for the British champion jockey title, Frankie Dettori, won the next race, the Juvenile, on Wilko.
The meeting's headline race, the Classic, was won by Ghostzapper, ridden by Javier Castellano.
Trained by Bobby Frankel, the one-time sprinter showed no problem with the one-and-a-quarter mile distance.
Roses in May, trained by Dale Romans and ridden by John Velazquez, was second, and last year's Classic winner, the Richard Mandella-trained Pleasantly Perfect, was third with Jerry Bailey aboard.
Ghostzapper, a four-year-old who has won all four of his races this year, turned for home with a short lead before pulling away.
It was Roses in May's first defeat in six races this year.
The earlier victories by Dettori and Fallon gave British horses an unexpected 100% record at the meeting.
Fallon made his move around the final bend and struck for home with a furlong to run.
Despite drifting right in the final stages, Ouija Board held on strongly.
Fallon said: "I have always rated her since the first time I sat on her in the spring.
"Most great fillies have got plenty of speed or stamina, but this one has got both. She has a real turn of foot."
Dunlop said that he would almost certainly not run the horse in the Japan Cup because she had shown signs of tiring after a long season.
Ouija Board went into her race the odds-on favourite, but Wilko was a 20-1 shot going into the Juvenile, his first race on dirt.
It was also Wilko's last race for Jeremy Noseda before being transferred into the care of California-based
Dettori, for whom this was a fourth career win at the Breeders' Cup held off the best of the American youngsters to win by three-quarters of a length from Afleet Alex.
Dettori made it two wins out of two for British horses
He said: "Passing the quarter-pole I thought we might just be a good fourth but then they didn't go anywhere in front and the dream came true.
"Jeremy asked me to ride him on a dirt surface in Newmarket last week and he handled it very well, but I don't think any of us really expected this.
"But you know what they say - if you haven't got the ticket, you can't win!"
