Image by Getty Images via @daylifeIt's an historic day in horse racing. Zenyatta just became the first female horse to win the Breeders' Cup Classic, the biggest thoroughbred race held in the United States. And the race didn't set-up easily for her either. She is still undefeated, now 14-0. It'll be interesting to see which of the female super-horses wins horse of the year, Zenyatta or Rachel Alexandra. Rachel Alexandra already beat the boys in the Preakness, the Haskell, and the Woodward, as well as the other three-year old fillies in the Kentucky Oaks and the Mother Goose (winning both by the largest margins in the history of those stakes). The probable Eclipse Award winner as this year's champion turf horse, Gio Ponti, came in second.
