Tiffany Case, a 12-year-old stakes-placed mare and dam of the top-ranked 3-year-old filly Nitrogen, will be offered in foal to the leading stallion Not This Time at the 2026 Keeneland January Horses of All Ages Sale. Owned by D.J. stable and consigned by Taylor Made Sales Agency, Tiffany Case has produced two stakes-winning foals, including Nitrogen, who has earned over $2 million with multiple Grade 1 victories and was named Canada’s champion 2-year-old filly. The mare is highly regarded for her proven production of elite talent and is expected to attract strong interest from buyers seeking quality broodmares.

Nitrogen has established herself as one of North America’s best turf and dirt fillies, highlighted by a dominant 17-length win in the Wonder Again Stakes and a victory in the prestigious Alabama Stakes against top competition. D.J. stable, with a history of campaigning Eclipse Award winners, continues to build on its success with Tiffany Case’s offspring, including a Gun Runner yearling retained for racing. The sale catalog will be available December 9, and Tiffany Case’s combination of pedigree, performance, and proven producing ability positions her as a standout broodmare prospect.
