Groupie Doll lived up to her favorite\'s billing with a dominant victory Saturday in the seven-furlong, $1 million Breeders\' Cup Filly and Mare Sprint. The 4-year-old trained by William Bradley made her move around the turn, cruising past Dust and Diamonds and thundering home under Rajiv Maragh to win by 4 1/2 lengths. Dust and Diamonds settled for second in the second of nine races on the Breeders\' Cup slate Saturday at Santa Anita and Switch was third.
