ARCADIA, Calif. - Dancing in Silks has pulled off a huge upset in the US$2 million Breeders' Cup Sprint, winning a four-horse photo finish by a nose.

The four-year-old gelding edged Crown of Thorns in Saturday's race at Santa Anita. Ridden by Joel Rosario, Dancing in Silks ran six furlongs in 1:08.14.

Carla Gaines became the third woman to train a Breeders' Cup winner, and the first since Laura de Seroux saddled Azeri to a victory in the 2002 Ladies' Classic.

Sent off at 25-1 odds, Dancing in Silks paid $52.60, $19.20 and $12. Crown of Thorns returned $13.20 and $8.60, while Cost of Freedom was another head back in third and paid $9.20 to show.

Gayego was fourth in the field of nine. Trainer Bob Baffert had his two-year winning streak in the race snapped when 9-5 favourite Zensational finished fifth.
