Breeders' Cup 2011: Why So You Think Will Steal Classic from Uncle Mo

Uncle Mo is the odds-on favorite to win the 2011 Breeders' Cup Classic, but So You Think is the horse to watch.

Uncle Mo's Cinderella story is easy to fall in love with and there is no questioning the horse's speed—but the length of the race will allow a promising dark horse to steal away a victory.

Uncle Mo pulled out of the Kentucky Derby and battled back from the liver disease cholangiohepatitis—and everyone is in the horse's corner. But hopes and good wishes won't bring this very talented horse a win.

So You Think has netted $7.5 million in his career. It's no accident that he's brought in more riches than any other horse in this race—and the fact that the oddsmakers barely even have him showing is a dream come true for bettors.

Races like the Juvenile Fillies in the Breeders' Cup may be too close to call, but the Classic doesn't feature nearly as many long shots.

So You Think's background on grass has many concerned with how he will perform on dirt. Will his speed on grass translate to dirt well enough to oust Uncle Mo?

Don't be worried. There are plenty of horses who have seen success on multiple surfaces. It's not as though race day will be the first time he's ever touched dirt in his career.

So You Think was built to run a race of this distance. With seven of his nine 10-furlong races rendering a winning result and two second-place finishes of the same distance under his belt, there is no doubt that he's going to have a strong run from start to finish.

So You Think may not be the odds-on favorite, but those putting too much stock in his grass background will be sorely disappointed when he defeats the feel-good horse of the year.
