Caesars Sportsbook promo code: Kentucky Derby preview Nineteen horses are set to run Saturday at Churchill Downs after Grande was scratched Friday due to a cracked heel that hasn’t healed in time. Journalism, trained by Mike McCarthy, opened as a 3-1 Morning Line favorite (see current odds at Caesars Racebook) and will start in the No. 8 post. He brings a four-race win streak into the Derby, including an April 5 victory in the Grade 1 San Anita Derby. Two other horses — Sovereignty (5-1 in the N. 18 post) and Sandman (6-1 at No. 17) — opened with single-digit odds. Sandman won the Arkansas Derby while Sovereignty was the runner-up in the Florida Derby. Hall of Fame trainer Bob Baffert is back with a pair of entrants — Rodriguez (12-1) and Citizen Bull (20-1) — at Churchill Downs after serving a four-year suspension.
