Authentic won the 146th running of the Kentucky Derby on Saturday in Louisville, Ky., holding off pre-race favorite Tiz The Law down the stretch.
The colt was piloted by jockey John Velazquez, who took home his fifth Triple Crown race and third Kentucky Derby. Authentic was trained by Bob Baffert, who has now won the Derby six times.
This year's race marked the third time the Derby has been held outside the month of May, and the first since 1945. It was also the first Derby run in the month of September, and the first time the Derby was not the first leg of the triple crown since 1931.
