The concern is allowing a racing program to proceed when a significant number of horses have been scratched due to track or weather conditions.
Large numbers of weather-related scratches can substantially reduce field sizes and negatively affect the overall quality and wagering appeal of a racing program. As the HBPA and the horsepeople it represents generate important revenues from pari-mutuel wagering, proceeding with a significantly reduced race card can negatively impact wagering handle and the revenues generated for the industry.
