The Elmont track, which served as a staging area for workers and emergency vehicles in the days following the attacks, said horses bearing the numbers were the first three winners Sunday, the New York Post reported Tuesday.
"The odds were probably about a million to one," said David Jacobson, the trainer at Drawing Away Stable, which owns the first two winners from Sunday.
"It's unimaginable. We were amazed."
The pick-three result paid $18.60 for a $2 bet, the racetrack said.
