Delightful Mary took a step toward more important engagements when rallying Monday to win the filly division of the $100,000 Ocala Breeders’ Sales Championship in Ocala, Fla. The race was one of four on the Day of Champions card, which has been held annually since 1990 for horses sold at OBS. All races are betless exhibitions for 3-year-olds, and all are run over a one-mile Safetrack synthetic surface.
