Bred by Order Of St George and out of a Jeremy mare, Rickety Kate comes from decent racing stock, but pedigree on its own tells you very little about what a horse will do under saddle and in front of a crowd. At four years old, the horse is older than many first-time racers, which might suggest patient handling—trainers don't usually wait this long unless they see something worth waiting for. With O'Brien's record this season, there is every reason to expect the yard has a plan. Whether Rickety Kate delivers on that plan is what happens next.
