The 4-year-old English-bred daughter of Frankel, who shipped in off of two straight Group 1 stakes wins, and jockey Frankie Dettori gave Europe its first win of the second day of World Championship racing at Santa Anita Park. Dettori and his mount were behind a wall of horses at the top of the stretch before rocketing into gear down the lane.
Canadian champion filly Moira finished a length behind Warm Heart in third. Final time for 1 ¼ miles miles on firm turf was 1:59.06.
“An amazing performance from an outstanding filly,” trainer John Gosden said. “Frankie said he was happy with her throughout the race having a good pitch on the inside rail. She traveled beautifully throughout and showed an electric turn of foot. Turning into the straight Frankie had to sit and suffer for a few strides but once she got out she flew home and won very well in the end.”
Dettori won his 15th World Championships race to move into a tie for third all-time with Joel Rosario.
