The 140th Kentucky Derby is set for Saturday at historic Churchill Downs.

"California Chrome" is the morning-line favorite at 5-to-2 and will break from post-position five.  

Hoppertunity was the second choice at 6-to-1, but was scratched on Thursday with a foot injury. Wicked Strong is next at 8-to-1, but will start from the outside in gate 20.  

Post-time for this year's "Run for the Roses" is 3:24 p.m. on Saturday.

Horse racing hasn't seen a Triple Crown winner since Affirmed won the Derby, Preakness Stakes and Belmont Stakes in 1978.
