Waggley, a 2-year-old filly by Life Is Good, remained a perfect 3-for-3 with a 4 ¾-length romp under Yedsit Hazlewood in the Prairie Gold Juvenile Fillies Stakes on Saturday at Prairie Meadows for trainer Wesley Ward. Waggley cruised to a 3 ½ length victory in her career debut at Keeneland in April before winning the Kentucky Juvenile Stakes Presented by Resolute Racing on a sloppy track three weeks later at Churchill Downs.
