"Obviously on her pedigree being by High Chaparral we felt she was going to be an Oaks horse and about this time last year after a few of her trials we thought about this race," said stable representative Charlie Duckworth.
"Right from her very first start we thought she had plenty of ability, although it's been a little while until today that she's rewarded us."
Youngstar is a half-sister to stakes-placed Eleven Seconds and is the best of four winners from Irish bred Danehill mare Starspangled (IRE), a sister to Group III winner Downtown and daughter of Champion 3YO Filly User Friendly, a five-time Group I winner.
Bowness Stud sold the current yearling from Starspangled, a filly by Adelaide (IRE), for $80,000 at Inglis Easter to Anton Koolman Bloodstock.
Starspangled has a weanling colt by Dissident and was covered last spring by High Chaparral's champion son Dundeel.
Youngstar is the 113th stakes-winner for the much missed classic sire High Chaparral, who has been enjoying further success as a sire of sires through his star son So You Think
