Big Apple
"Big Apple" is a nickname for New York City. It was first popularized in the 1920s by John J. Fitz Gerald, a sports writer for the "New York Morning Telegraph". Its popularity since the 1970s is due in part to a promotional campaign by the New York tourist authorities.
New York Derby
The New York Derby is the second leg of the "Big Apple Triple," a grouping created in 1999 consisting of three races at three different racetracks in New York state and restricted to three-year-olds bred in New York state. A horse who wins all three of the Big Apple Triple wins the purse total of $400,000 plus a $250,000 bonus. The first leg is the Mike Lee Stakes run at Belmont Park, and the third leg is the Albany Stakes at Saratoga Race Course.
