Oh, what the heck, I"ll pile on too. I had $25 WPS on the 10, and I agree it was a clearcut, easy call to DQ. I suspected it would happen as soon as 10 crossed the line (thought to myself, "geesh, won't win this one, either!"

)
Nobody ever said there was bumping. The 10 clearly, repeatedly, came over in front of the other horse, causing that horse to
have to alter it's path.
I don't know why it took so long, I suspect they were figuring out what they would have to do with the 9.
