2015: American Pharoah
American Pharoah became the first horse since 1978 to win the Triple Crown when he won the 147th Belmont Stakes on Saturday.
The Kentucky Derby and Preakness Stakes champion, American Pharoah began the day as a 3-to-5 favorite in the morning betting line, and those were the odds when the race began. He started from the fifth position in a field of eight.
American Pharoah becomes the 12th horse to win the Triple Crown, beginning with Sir Barton in 1919 and most recently Affirmed in 1978. After Affirmed's Triple Crown win, 12 horses won the first two legs of the Triple, only to lose the bid at the Belmont, either because of an upset or because they did not start or complete the race.
