It's one of the biggest American horse racing events of years, behind only the Kentucky Derby — and the Belmont Stakes when a Triple Crown bid still is alive.
The Breeders' Cup showcases many of the best racehorses in the world, all running for championships in 14 divisions spread over two days that each carry at least a $1 million purse.
The big event rotates among some of the nation's most historic tracks, and this year is taking place in the heart of horse-breeding country — at Keeneland, in Lexington, Ky.
After charging out of the gate Friday with five races, the festivities swing into high gear Saturday with nine more beginning with the Filly and Mare Sprint at 10:50 a.
