Justify completed the Triple Crown by winning the 150th Belmont Stakes on Saturday.
It's the second Triple Crown winner since 2015 and the 13th since it was first done almost 100 years ago.
Hall of Fame Trainer Bob Baffert also made history. It's his second time winning accomplishing the feat.
Baffert's American Pharoah won it in 2015. He's only the second trainer to get two Triple Crowns.
