Speed is the name of the game in horse racing, but fame and glory usually gravitate toward those horses with the stamina to negotiate longer distances of ground in two-turn classics.

Sprinters, the horses who can generate electrifying fractions, are usually in the background, except for a handful of champions who possessed speed so dazzling it left a lasting impression on anyone who ever watched them rocket to the winner’s circle.

Housebuster was one of those brilliant sprinters.

Few horses have been able to blend the kind of success that Unbridled enjoyed both on the racetrack and in the breeding shed.

A strapping, 17-hand colt with a long, ground-gobbling stride, he was slow to develop at 2 after a promising 10 ½-length victory in his career debut. The son of Fappiano was then plagued by a sore hoof at 4, succinctly explaining why he won just eight of 24 career starts.
