It was a good Saturday for one lucky horse racing bettor, who turned a 50-cent Pick 5 into over half a million dollars.

One bettor won the Early Pick 5 -- correctly picking the winner of the first five races -- of Saturday's 13-race program at Gulfstream Park in Hallandale Beach, Florida and took home $524,966.50.

According to Ed DeRosa, the payout was the fifth-highest for a Pick 5 in U.S. horse racing history and the third-highest for a non jackpot.

The winning horses for the first five races were No. 8 Freddy Soto, No. 4 Union Lane, No. 1 He's a Babe, No. 3 Enzoexpress and No. 6 Lashara.

It was a big day for long shots, as Freddy Soto, winner of the first race at 73-1 odds, had beaten a total of five horses in his previous three races prior to Saturday's win, while No. 4 Union Lane had finished in front of 11 total horses in her previous seven races.

With 100% of commercial casinos closed in the United States, according to the American Gaming Association, and most professional sports on hold, horse racing is one of the few remaining legal wagering options for U.S. sports bettors.
