Baffert is back with another likely favorite in Justify. His rival, Todd Pletcher, will saddle Audible and Magnum Moon, two horses that have answered every question asked of them this year. There's Chad Brown-trained Good Magic, who won the Breeders' Cup Juvenile. There's Bolt d'Oro, the favorite for many analysts until he lost to Justify in the Santa Anita Derby. And for a tinge of the exotic, there's Mendelssohn, who dusted the competition in Dubai to such a degree that even skeptics believe he could break the glass ceiling that has always existed for international horses coming to Churchill Downs.
