Untapable put the finishing touches on her 3-year-old filly championship campaign when she won the $2 million Longines Breeders' Cup Distaff (gr. I) 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.
Untapable, the Longines Kentucky Oaks (gr. I) winner posted her fourth grade I win of the season while collecting her sixth triumph from seven starts overall this year.
Untapable was making her second start at Santa Anita after running eighth in last year's Breeders' Cup Juvenile Fillies (gr. I). Friday's victory was her eighth win from 11 lifetime starts.
The bay filly out of the Prized mare Fun House paid $5.20 win as the 8-5 favorite in the field of 11. The running time for the 1 1/8-mile test was 1:48.68.
Making a sweeping move on the outside for Napravnik, Untapable grabbed the lead in the stretch after engaging a determined Iotapa. She lengthened stride under urging in the final furlong to win impressively.
