Favored Ouija Board rolled to her second victory in the Emirates Ariline Breeders' Cup Filly and Mare Turf (gr. IT), adding a 2 1/4-length triumph Saturday at Churchill Downs to her victory at Lone Star Park in 2004. The European star was making her third appearance in the race after finishing second last year at Belmont Park. She is the fifth two-time winner of a Breeders Cup World Championship event."She's a super mare," declared Ouija Board's rider, Frankie Dettori. "She's definitely the best filly in the world, without a doubt.Carrying the colors of Lord Derby and trained by Edward Dunlop, Ouija Board covered the 1 3/9 miles in 2:14.55. She rallied from the outside in the stretch to grab the win."She's the best; there's no other way to say it," Dunlop said. "She's an absolute champion."Film Maker finished second, just like she did against Ouija Board in the Filly & Mare Turf's 2004 edition. Film Maker was a neck in front of Honey Ryder this year while Wait a While finished 1 3/4 lengths farther back in fourth. Early leader Dancing Edie faded to eighth after posting fractions of :25.14 and :49.77. My Typhoon, who surged to the front while on the backstretch approaching the final turn, dropped back to sixth.
