ARCADIA, Calif. – Eight years after becoming the youngest jockey to win a Breeders’ Cup race, Joseph O’Brien became the youngest trainer to accomplish that feat when his Iridessa outfinished Vasilika by a neck to win the $2 million Breeders’ Cup Filly and Mare Turf at Santa Anita.
O’Brien was 18 years old when he guided St. Nicholas Abbey to victory in the 2011 Breeders’ Cup Turf for his father, the trainer Aidan O'Brien. He is now 26, one year younger than Craig Dollase was when he saddled Reraise to win the 1998 Sprint.
