North Ridge is a daughter of Ivan Denisovich, who stands at leading Chilean stud Haras Don Alberto. A beautifully bred son of Danehill and 1993 American champion 3-year-old filly Hollywood Wildcat (by Kris S.), Ivan Denisovich is closely related to War Chant (Danzig x Hollywood Wildcat). He won the 2005 TNT July Stakes (ENG-G2) as a juvenile and placed in five Grade/Group 1 stakes at 2 and 3. North Ridge is his third Las Oaks winner, following Marie Madelaine in 2016 and Mama Lili in 2022.
A half sister to Group 3-placed Diocleziano (by No Nay Never), North Ridge is out of Group 3-placed Nueva Castilla, a half sister to Neroli (like North Ridge, a daughter of Ivan Denisovich) and to 2018 Chilean champion older male Nuevo Maestro (also by Ivan Denisovich). Sired by listed stakes winner and Arlington Park track record setter Pavarotti (A.P. Indy x Snow Forest, by Woodman), Nueva Castilla is also a half sister to Nettina (by Ivan Denisovich), a multiple Group 3 winner who was runner up to Mama Lili in the 2022 Las Oaks.
Nueva Castlla and her siblings are out of Netta (by seven-time Chilean champion sire Hussonet), whose dam Vitra (by multiple Group stakes winner Wagon Master, by Rainbow Quest) won the 2001 Premio Carlos Campino (CHI-G2). Produced from the Roy mare Villa Torlonia (a full sister to 1994 Chilean Mare of the Year Via Sixtina), Vitra is a half sister to Grade 3-placed Ramatuelle (by 1993 Citation Handicap, USA-G2, winner Jeune Homme, by Nureyev), dam of 2014 Sentient Jet Breeders’ Cup Juvenile (USA-G1) winner Texas Red (by Afleet Alex). This family is a Chilean branch of a major Argentine branch of Bruce Lowe family 3-b which came to Chile via Villa Torlonia’s dam Noble Sixtina (by Noble Quillo).
North Ridge is inbred 4x5x4 to Mr. Prospector, not an uncommon pattern nowadays in the Americas. As she is only halfway through her 3-year-old year by Southern Hemisphere standards, she should have several more opportunities to confirm the form she showed in Las Oaks (her first win at the top level) before she retires to the paddocks.
