Saratoga Race Course will host the $500,000 Grade 1 Diana Stakes, with Canada’s Horse of the Year Moira set to take on a strong field that includes several contenders from the powerful Chad Brown stable. The race marks the seasonal debut for the 5-year-old Ghostzapper mare, who is looking to bounce back from a troubled third-place finish in the Breeders’ Cup Filly and Mare Turf.
