Untapable put the finishing touches on her 3-year-old filly championship campaign when she won the $2 million Longines Breeders' Cup Distaff in a driving finish Oct. 31 at Santa Anita Park.

Facing older rivals for the first time, Winchell Thoroughbreds' Kentucky homebred daughter of Tapit scored by 1-1/4 lengths over Don't Tell Sophia and Iotapa with jockey Rosie Napravnik aboard for trainer Steve Asmussen.

Immediately after the race, Napravnik announced her retirement from racing on national television, effective after the completion of the Breeders' Cup Saturday, Nov. 1, in order to start a family.
