For the fourth year in a row, America’s Best Racing is challenging some of the brightest minds in horse betting to come up with their top three picks for key races every weekend leading up to the Breeders’ Cup World Championships. The handicappers face off in what we like to call “Big-Race Showdown.”

Saturday’s Grade 1, $250,000 Bing Crosby Stakes at Del Mar is a Challenge Series “Win & You’re In” qualifier for the Breeders’ Cup Sprint this fall and as such 10 horses, including three shipping in from other tracks, signed on to contend.
