Ky Derby Factoids.

[Merlinsky]

What Kentucky Derby winners won the Derby after their sire died? Secretariat (Bold Ruler); Strike the Gold (Alydar); Fusaichi Pegasus (Mr. Prospector); Super Saver (Maria's Mon). Any others?

Union Rags and Liaison are a couple that could be added to this sort of list. I feel like every so often there were highly regarded horses going in with that trivia as part of their bio, but they failed to win one for the dearly departed old man.
