Chief White Fox is by the late sire The White Fox, who also was registered by The Jockey Club as "white." The White Fox was out of the dam Patchen Beauty, who also is registered as "white," as was Patchen Beauty's dam, Precious Beauty, and Precious Beauty's maternal grand-dam, White Beauty.
To be recognized as officially "white," a Thoroughbred must have no trace hairs of a darker color, which would make it gray or roan.
Chief White Fox had never finished better than fourth in his previous starts. In Monday's race, he came from off the pace to win by 5 1/4 lengths with an eye-catching stretch run.
