Below are the detailed rules for instances in which the track's surface has changed resulting in a change or update to the specific race (i.e. Dirt changed to Turf, etc.). Certain states and specific tracks may change the track surface type, at their discretion, based on the track conditions prior to a race.
In some cases, a change in the surface may declare a race an "all win" for specific wager types.
New York Main Track to Turf move - Pick 4, Pick 6, and Grand Slam
When the condition of the turf course(s) warrants a change of racing surface in any of the legs of the Pick 4 and/or Pick 6, and such change has not been known to the public prior to the close of wagering for the Pick 4 and/or Pick 6, the stewards shall declare the changed leg(s) an "all win" race for Pick 4 and/or Pick 6 wagering purposes only. An "all win" race will assign the winner of that race to each Pick 4 and/or Pick 6 ticket holder as their selection for that race.
Kentucky and California Tracks Turf Course Surface Change - Pick 4 and Pick 6
When the condition of the turf course warrants a change of racing surface in any races of the Pick 4 or Pick-6, and such change has not been disclosed to the public prior to "off-time" of the first race of the Pick-6, the stewards shall declare the changed races an "all win" race for Pick 4 or Pick-6 wagering purposes only.
Florida Tracks Turf Course Surface Change - Pick 4, pick 5
When the condition of the turf course warrants a change of racing surface in any races of the Pick 4 or Pick-5, and such change has not been disclosed to the public prior to "off-time" of the first race of the Pick-4 or 5, the stewards shall declare the changed races an "all win" race for Pick 4 or 5 wagering purposes only.
