Prominent U.S. runners have played a key role in the development of the Japanese breeding and racing program into an international superpower. Chief among those, of course, is Horse of the Year Sunday Silence, with the 1989 Kentucky Derby, Preakness, and Breeders’ Cup Classic winner becoming a breed-shaping sire in Japan.
Sunday Silence appears in the pedigree of all four Japanese-bred colts who are considered potential Kentucky Derby candidates. However, other American expatriates figure prominently in this quartet, as well.
