Zenyatta lost the 2010 Breeders Cup by a minuscule margin, and ended her bid for a perfect career.
She is horse racing's biggest star, yet a six-year old mare was able to knock her off the pinnacle of the sport in her route to winning the $5 million Breeders' Cup Classic in Churchill Downs.
With Blame having a significant lead towards the end, Zenyatta scurried up in retaliation. However, her efforts were not enough to claim the victory. In the end, Blame won by a head.
Heading into the race, Zenyatta came in with the hopes of improving her career record to 20-0. The six-year old thoroughbred mare was widely considered the heavy favorite to win the race. Of course, today we witnessed that greatness can't continue on forever.
Fly Down finished with third place, while Lookin At Lucky finished fourth.
