LOUISVILLE, Ky. - Louisiana Derby winner Revolutionary and Santa Anita Derby winner Goldencents were, somewhat surprisingly, the 5-1 co-choices over Florida Derby winner Orb when advance wagering closed for Saturday’s Kentucky Derby early Friday evening. [DRF LIVE AT THE KENTUCKY DERBY: News updates, photos, videos] Orb, pegged the likely favorite for the Derby at 7-2 on Churchill Downs oddsmaker Mike Battaglia’s morning line, was 6-1 with nearly $600,000 wagered in the win pool on Friday. Normandy Invasion was the only other member of the 19-horse field to close at single-digit odds at 8-1. Black Onyx was scratched earlier in the day. Perhaps the most surprising price on the board after the opening day of wagering was the 11-1 on the undefeated Verrazano.  Florida Derby runner-up Itsmyluckyday also closed at 11-1. In contrast Frac Daddy, 50-1 on Battaglia’s line, was bet down to 15-1 in the early wagering. The Kentucky Oaks/Kentucky Derby double will-pays were all big ones following Princess of Sylmar’s shocking win in Friday’s Oaks and suggest Orb will be the post-time favorite for the Derby. The $2 Princess of Sylmar-Orb daily double payoff is the lowest on the board at $621.40, followed by Revolutionary, $790; Normandy Invasion, $742; Verrazano, $804.60; and Goldencents, $953.60.  A total of $2,538,808 was wagered in the Oaks/Derby pool.
