"The reality really hasn't sunk in, but I said I would and I am sticking with it," said Black, 61, whose first win came at Liberty Bell Park, a now-closed track in nearby Philadelphia, in 1970. Black was just out of high school at the time.
Black added, "The best part is I did it on my son's horse."
Smart Tori, owned by Black's son Anthony, paid $4.40 to win, $2.60 to place and $2.20 to show on Monday, the Philadelphia Inquirer reported.
