Switch, the second choice on the morning line for the Breeders’ Cup Filly and Mare Sprint at Churchill Downs on Friday, will be withdrawn from the Keeneland sale on Monday and will race next year at 5, according to trainer John Sadler. “The original plan was to sell her, but we’ve decided recently to go on and run her again,” Sadler said. “That’s good news for us.” Turbulent Descent, the solid favorite for the Filly and Mare Sprint, also will be withdrawn from the Fasig-Tipton sale on Sunday and will race next year, according to trainer Mike Puype.
