The jockey of the moment will make her Breeders’ Cup debut and also take her first ride for Aidan O’Brien in Kentucky

It has already been a season of firsts for Hollie Doyle and the jockey of the moment will break new ground again on Friday, when she will take her first ride for Aidan O’Brien – replacing his stable jockey, Ryan Moore – in a $150,000 race on the Breeders’ Cup undercard, shortly before making her Breeders’ Cup debut on Mighty Gurkha in the Juvenile Turf Sprint.
Moore was initially booked to ride Order Of Australia in the Bryan Station Stakes for three-year-olds, the third race on the card at Keeneland on Friday, but O’Brien’s colt is set to carry 8st 6lb, which is Moore’s lowest riding weight over the last six months.
