This Day in History: 1974-02-09

Jockey Chris McCarron rode his first winner, a five-year-old gelding named Erezev, at Bowie Racecourse. By year’s end, McCarron had established a then-record number of winners for a single season: 546. Fifteen years later, on Nov. 30, 1989, jockey Kent Desormeaux eclipsed that mark.
