Sabercat in his stall on Tuesday morning. Corey Nakatani, a two-time Kentucky Oaks winner and nine-time Breeders' Cup winner, will be aboard for trainer Steve Asmussen. "The complexion from five days out to when they leave the gate, the pace scenario can change so much. We were witness to that last year, with how much speed Uncle Mo had and then he doesn't run. It just changed the complexion of the race so much. When they leave the gate that'll be when it matters."
