As much as I detest the cruel sport of horse racing, I’m still stunned by the story of the sports book that wouldn’t pay off a guy’s Kentucky Derby bet in full because it claimed it was over their limit.

That didn’t stop them from accepting the bet, and if he’d lost they would have kept all of his money. But when his unlikely winner came through, instead of giving him the $609,000 he was owed, the book capped his payout at $35,000.

The bettor has appealed to the Nevada Gaming Commission, which should put a stop to this practice immediately but, like most state-level groups that are supposed to oversee all legal gambling operations and protect consumers, they’ll likely side with the sports book operator, William Hill.

Now that word of this ripoff has gotten out, I don’t know why anyone would ever put a bet of any kind down in a William Hill book.
