This year marks the 50th anniversary of Canonero II posting arguably the most improbable upset in Derby history.
Canonero quickly became the darling of Venezuela, where the colt had trained prior to making an arduous journey to the U.S. to win the 1971 Derby as a member of the mutuel field. The $1,200 yearling purchase went on to win the Preakness but faded to fourth in the Belmont Stakes.
