When Rosie Napravnik rides Vicar's In Trouble at Churchill Downs Saturday, she will be attempting to become the first female jockey to win the Kentucky Derby -- or to finish in the money. Since Diane Crump broke the gender barrier in 1970, women have had mounts on eight Derby starters, and the best performance by any of them was Napravnik's fifth-place finish on Mylute last year.

Eventually a woman will win this race -- and Napravnik could be the one to do it. Julie Krone became the first of her sex to capture a Triple Crown race when she scored aboard Colonial Affair in 1993. Krone was an exceptional talent -- she competed successfully against men at the top level -- and Napravnik is the best female rider since Krone. She has already won a Kentucky Oaks and a Breeders Cup race. She has a chance with Vicar's in Trouble -- the winner of the Louisiana Derby -- and at 26, she can probably look forward to many other opportunities to ride in America's greatest race.
