FROSTED

Winner of the Wood Memorial by two lengths, he has undergone the biggest transformation of any Derby runner. After inexplicably stopping at the top of the stretch in the Fountain of Youth, Frosted had Kieran McLaughlin scratching his head. The trainer decided to change jockeys and go with Joel Rosario, who won the 2013 Derby with Orb. He then moved Frosted from Florida back to New York, where he won his first career race, adjusted his blinkers that restrict his vision and had him undergo a minor throat procedure to help his breathing. The biggest question is whether he can handle the longer Kentucky race. He has two wins in seven career starts.
