Actually, Crist seems to have reported this on Saturday. Strange that it didn't get more airplay. Wait, no it isn't.
7:10 pm: Rinterval's trainer, Eric Reed, just said in an ESPN interview that Hollywood Park security told him that there had been "death threats" against his filly this week for running against Zenyatta, and that it was fans holding up Zenyatta signs that just spooked her and caused her to rear up in the paddock. ESPN then reported that RInterval will run in the Spinster next Sunday.
