It will go down in betting lore as the $9 million disqualification.
Kentucky Derby favorite Maximum Security crossed the finish line first but was subsequently disqualified, making long shot Country House the winner. It cost bettors who backed Maximum Security to win, place or show approximately $9 million, according to betting statistics provided by online horse racing site TwinSpires.com.
Maximum Security closed at 9-2 and appeared to hold off the field on a rain-soaked, sloppy track at Churchill Downs in Louisville, Kentucky. An objection was filed accusing Maximum Security of interfering with other horses, and race officials reversed the decision, giving Country House the victory.
