Her dam Soda Water (Encosta de Lago) is a half-sister to Group III winner and Group 1-placed Intelligent Star, Group III winner Blaze The Turf, and the unraced Aerate's Pick, dam of triple Group 1 winner Ortensia.
The Group II BRC Champagne Classic and Group III ATC Breeders' Plate winner, Dubious, stood three seasons at Aquis.
The son of Not A Single Doubt covered 417 mares in his first three seasons before moving to Kitchwin Hills this season at a fee of $15,400.
