Secretariat, the 1972 Horse of the Year, cools off in New York on March 17, 1973, after winning the seven furlong Bay Shore Stakes at Aqueduct by four and a half lengths in his debut as a 3-year-old. “He’s just like he was, good,” said jockey Ron Turcotte (checked shirt) after Secretariat’s explosive stretch run that took him to victory over Champagne Charlie.
