Since Nijinsky, only Nashwan (1989), Sea the Stars (2009), and Camelot (2012) have won both the Guineas and the Derby. Between Reference Point in 1987 and Camelot in 2012, no Derby winner (not even the potential Triple Crown winners Nashwan and Sea the Stars) even entered the St. Leger. This reluctance to compete in the St. Leger is said to be because of the impact it would have on a horse's stud value in a market where speed is preferred to stamina.
