Aidan O’Brien’s top filly Warm Heart goes back to the US to take on 11 rivals in this nine-furlong contest for the 1st Grade 1 Bet Pegasus World Cup Turf Invitational Stakes (Sky 9.55).

A narrow loss to Inspiral in the Breeders’ Cup Filly and Mare preceded another fine run in Hong Kong where she finished third over a mile and a half to Junko in the Group 1 Longines Hong Kong Vase. Her best form is over the mile and a half so the distance here is a bit of a concern. The filly is due to be retired after this race.
