BRITISH jockey Sophie Doyle enjoyed her biggest win in the US when Fioretti stayed on strongly to win the Thoroughbred Club of America Stakes (Grade 2) at Keeneland last Saturday. The Bernardini filly trained by Anthony J. Hamilton Jr is likely to contest the Fillies Sprint at the Breeders’ Cup meeting. She had three-quarters of a length to spare over Heykittykittykitty with even-money favourite Judy The Beauty, who won last year’s Sprint, back in third.
