On this day in 1919, Sir Barton won the Belmont Stakes, becoming the first winner of the Triple Crown of American horse racing. Sir Barton had previously won the Kentucky Derby and the Preakness Stakes earlier in the year, making him the first horse to win all three races. His historic feat paved the way for future horses to chase after the elusive Triple Crown. Sir Barton solidified his place in history as one of the greatest racehorses of all time.
