ARCADIA, Calif. – River Tiber, the 3-1 morning-line favorite for Friday’s $1 million Breeders’ Cup Juvenile Turf at Santa Anita, was scratched from the race Friday morning, the Breeders’ Cup reported. The official reason given for the scratch is trainer withdrawal. Attempts to reach trainer Aidan O’Brien were unsuccessful early Friday morning. O’Brien will still have the likely favorite in the Juvenile Turf in Unquestionable, who was the 4-1 morning-line second choice. Ryan Moore, who was named on River Tiber, will replace Frankie Dettori on Unquestionable. :: Get Breeders' Cup Clocker Reports from Mike Welsch and the DRF Clocker Team when you purchase a BC VIP Package!
