"We wasn't sure about the mile but Ryan gave her a brilliant ride," O'Brien said. "Michael was very confident that this was the race for her. It's incredible, really. I'm so delighted for everyone."
For their second wins of the day, Moore and O'Brien collected their fifth career wins in the Juvenile Turf when Victoria Road captured the mile race by a nose for the Irish horse's fourth win in a row.

Appleby, a seven-time winner in 12 Breeders' Cup starts, won last year's Turf, Mile and Juvenile Turf before making it four in a row.
"Fantastic ride by William," Appleby said. "He got him to the lead on the back turn there and made a lovely run up the inside."
