The first day at Ascot saw a record broken, as Miss Andretti won the King's Stand Stakes over five furlongs, crossing the line in 57.44 seconds, more than two seconds faster than any other horse in history.
For jockey Craig Newitt it was the biggest victory in his career so far. "I don't know what to think," Mr Newitt said. "My head's spinning, it's almost too much."
Trained by Lee Freedman, the Australian filly was the 3-1 favourite and beat Irish sprinter Dandy Man by one-and-three-quarters lengths.
Australian horses also came fourth third and fourth, in the form of Magnus and last year's winner, Takeover Target.
Lee Freedman said he was as proud of the victory as he had been of wins on his home turf. "It's up there with the Melbourne Cups," Freedman said. "For an Australian trainer there is nothing like winning our biggest race, but this is another dimension. This is harder in a lot of ways to bring a horse this far and win."
Australia has dominated the King's Stand Stakes for some years now, with Miss Andretti's latest win making it the third for horses from down under in the past five years.
