Clark Brewster talks about Cogburn, the world's fastest horse, on Breeders' Cup eve

Clark Brewster, who co-owns Cogburn with Bill and Corinne Heiligbrodt, talks about the fastest horse in the world with Danny Brewer, our man on the scene at Del Mar. Cogburn, trained by Steve Asmussen, is the favorite for Saturday's $1 million Breeders' Cup Turf Sprint. Cogburn set a world record for 5 1/2 furlongs when he won Saratoga's G1 Jaipur on turf. In his next start, he won Kentucky Downs' $2 million Ainsworth Turf Sprint (G2). Video starts with the Kentucky Downs stretch run.
