Triple Crown winners through the years, from Justify to Sir Barton

Horse racing fans witnessed a historical achievement at Saturday’s Belmont Stakes.

In the June 9 race, Justify, a chestnut colt that won both the Kentucky Derby and the Preakness Stakes, became the first Triple Crown winner since American Pharoah in 2015 and the 13th horse to win the Triple Crown since Sir Barton first claimed the title in 1919.

The young horse was largely favored to win Belmont on Saturday.

WILL JUSTIFY WIN THE TRIPLE CROWN? MEET THE UNDEFEATED COLT THAT COULD BECOME A HORSE RACING LEGEND

While other thoroughbreds such as Bravazo, Vino Rosso and Hofburg posed a threat to Justify’s Triple Crown feat, the colt is no stranger to overcoming the odds. After winning the Kentucky Derby, Justify became the first horse since 1882 to win the race without first competing as a 2-year-old.
