LOUISVILLE, Ky. (AP) — Brad Cox is looking to make history at Churchill Downs and the Kentucky Derby. The trainer grew up a few blocks away from the historic track. He began working with horses at Churchill Downs as a teenager before learning under several trainers and branching out on his own 16 years ago. Cox now has an Eclipse Award along with the likely Kentucky Derby favorite in 5-0 Essential Quality. The colt could make Cox the first Louisville-born Derby winning trainer. That would add to an impressive resume’ that includes two Oaks victories for fillies in three years.
