Frosted's sire is Tapit, and Frosted's great-grandsire is A.P. Indy. Frosted spent much of his 3-year old year chasing another AP, American Pharoah. Frosted finished 4th, about 3 lengths behind Pharoah in the Derby, 2nd to him in the Belmont, next to him in 3rd in the Travers after dueling with him, but faded to 7th in Pharoah's Breeders' Cup Classic. Frosted won the Wood Memorial and Pennsylvania Derby.
