Three stakes winners from last month's West Virginia Breeders' Classic program will challenge defending champion Saxet Heights in a highly competitive field of 10 statebred fillies and mares in Saturday night's $50,000 My Sister Pearl Stakes at Charles Town. Aspenglow, winner of the $250,000 Cavada, Stowe White, who dominated the West Virginia Division of Tourism for 3-year-old fillies, and Devonspaintedlady, who upset the nine-furlong Distaff, all bring sharp form into the 1 1/8-mile My Sister Pearl. The 4-year-old Aspenglow, based at Laurel Park with trainer Gary Capuano, is 10 for 12 lifetime at Charles Town, but will be stretching out beyond seven furlongs for the first time and must overcome post 10 in the three-turn race over the bullring. Trainer Jeff Runco has the coupled entry of Stowe White and Saxet Heights. Stowe White, one of three winners for Runco on the West Virginia Breeders' Classic program, has raced beyond seven furlongs just once in her 15-race career, finishing a distant seventh after a stumbling start in last month's Maryland Million Oaks at one mile. Saxet Heights, a nine-time winner locally, most recently finished third in the seven-furlong Maryland Million Distaff Handicap on Oct. 2, her first start since August. She and Devonspaintedlady are the only horses in the field to have won going nine furlongs. The field also includes Natures Annuity, who outran her 16-1 odds to finish second to Aspenglow in the Cavada, and Silver Heart, the Cavada's third-place finisher. Silver Heart is coupled with Aspenglow.
