Heavy rain has postponed early morning workouts at Churchill Downs, where all 20 Kentucky Derby horses are still expected to start. Most turf races were being moved to the main dirt track today, at least until late in the day. That sparked numerous scratches in minor races. Kentucky state veterinarian Bryce Peckham said he knew of at least 15-20 horses that wouldn't be running in the Derby undercard.
Many trainers, including Nick Zito and D. Wayne Lukas, were out early to watch their horses walk inside their covered barns instead of the track. The National Weather Service says only light rainfall is expected this afternoon ahead of the 6:28pm Derby post, with heavier showers overnight.
