Mr. Prospector
Mr. Prospector sired one winner of each of the Triple Crown races, a feat his grandson, Unbridled, also accomplished. His Triple Crown race winners were 2000 Kentucky Derby winner Fusaichi Pegasus; 1985 Preakness Stakes winner Tank's Prospect; and 1982 Belmont Stakes winner and American Horse of the Year Conquistador Cielo. Mr. Prospector's bloodline has been highly influential in the top echelons of Thoroughbred racing. All eight horses entered into the 2015 Belmont Stakes were descendants, through their sires, of Mr. Prospector. Similarly, all of the horses in the 2018 Kentucky Derby were descendants of Mr. Prospector.
