LOUISVILLE, Ky. – The Puma, the fifth choice at 8-1 in the early wagering for Saturday’s 152nd Kentucky Derby at Churchill Downs, was scratched about 12 hours before the race was scheduled to be run due to a swollen pastern believed to be caused by a skin infection in his left front leg.
Gustavo Delgado Jr., the assistant trainer to his father Gustavo Delgado, said Saturday morning that when he got to the barn the groom of The Puma informed him the horse had a swollen leg.
