FILE - In this Nov. 5, 2011, file photo, Ramon Dominguez, right, riding Hansen, passes Javier Castellano on Union Rags to win the Juvenile race at the Breeders' Cup horse races at Churchill Downs in Louisville, Ky. Those two horse, plus Dullahan, Daddy Long Legs, Creative Cause, Take Charge Indy, Alpha, Optimizer and Prospective are expected to line up again on Saturday, May 5, in the Kentucky Derby, just six months after the Breeders' Cup Juvenile on the same Churchill Downs track set the stage for the Run for the Roses.
