a :30-second commercial of the upcoming documentary film, Born To Rein, was played on Churchill Downs' "The Big Board" – the world’s largest 4K video screen in all of sports. Born To Rein honors Minatare, Nebraska native, John A. Nerud -- who was instrumental in co-founding the Breeders' Cup and served as its inaugural marketing committee chairman -- along with fellow Nebraskans, father-and-son trainers, Marion and Jack Van Berg of Columbus.
