One of the most exciting events in sports goes down on Saturday at Churchill Downs when Kentucky Derby 150 commences. The Run for the Roses has a post time this year of 6:57 p.m. Eastern. A European jockey will get his first ride in the Kentucky Derby on Saturday. Irishman Ben Curtis moved to the United States six months ago, and now has the mount on Derby contender Honor Marie. According to CBS, Todd Pletcher-Trained Fierceness is the favorite at 5-to-2 odds. Sierra Leone has the second-best odds at 3-to-1 and Catching Freedom has the third-best odds at 8-to-1.
