LOUISVILLE, Ky. - Rough Sailing, who slipped and fell going into the first turn of the Breeders’ Cup Juvenile Turf, had to be euthanized shortly after the race because of a broken shoulder, according to Hilary Pridham, assistant to trainer Mike Stidham. Pridham said three veterinarians had examined Rough Sailing when the horse was brought back to the barn housing Stidham’s horses on the Churchill backstretch, and all had determined through feeling the affected area that the shoulder had been badly fractured, and that there was no chance to save the horse.
