Keeneland To Offer Nitrogen’s Dam Tiffany Case At January Horses Of All Ages Sale

[Wandering Eyes]

Keeneland will offer the dam of top-ranked 3-year-old filly Nitrogen (Medaglia d'Oro), Tiffany Case (Uncle Mo)–who is in foal to red-hot sire Not This Time–during the 2026 January Horses of All Ages sale on Monday, Jan. 12, the auction company said via a Friday release.

Taylor Made Sales Agency, agent, is consigning the 12-year-old, a winning stakes-placed mare whose two foals to race are both stakes winners.

“Tiffany Case transcends mere investment value–she's young, proven and in foal to arguably the top stallion in the country,” said Jonathan Green, general manager of owner D.J. Stable. “She can be a cornerstone for any elite breeding program.”

Bred in Kentucky by JSM Equine and Greathouse Horse Property, Tiffany Case is a half-sister to Grade III winner and Grade I-placed Talk Veuve to Me (Violence). She was acquired by Leonard and Jon Green's D.J. Stable at the 2019 Keeneland November Breeding Stock sale while carrying her first foal by Violence. The resulting filly is stakes winner and Grade II-placed Love to Shop.

Tiffany Case's second foal to race is Nitrogen, campaigned with notable success by D.J. Stable. Voted Canada's champion 2-year-old filly last year when she was third in the GI John Deere Breeders' Cup Juvenile Fillies Turf, she has six victories and three seconds in nine starts in 2025 to push her career earnings past $2-million.

“I've said many times that Nitrogen is the best-looking Medaglia d'Oro filly I have seen since [Racing Hall of Famer] Songbird,” Taylor Made President and CEO Mark Taylor said. “Tiffany Case is the rare type of mare who is a proven producer of elite Grade I talent and stunning looks in her foals.”

Earlier this season, Nitrogen established herself as the best sophomore turf filly in North America before showcasing her versatile talent on the dirt at Saratoga. There she coasted to a 17-length win in the GIII Wonder Again Stakes, which was rained off the turf. Nitrogen next scored a 1 1/2-length victory in the GI Alabama Stakes.

Nitrogen remained on the dirt and finished second to older rivals in her two remaining races, the GI Juddmonte Spinster at Keeneland and the GI Longines Breeders' Cup Distaff at Del Mar.

“With Nitrogen firmly in the conversation for this year's champion 3-year-old filly honors, Tiffany Case represents a rare opportunity to add a proven, top-level producer to any broodmare band,” Keeneland Vice President of Sales Tony Lacy said. “Her produce record–paired with a sought-after Not This Time cover–underscores the quality and consistency she brings. She is a clear standout in any sale, and we expect her to draw serious attention from domestic and international buyers who value pedigree, performance and long-term potential.”

Tiffany Case has a Gun Runner yearling filly named Sniper that D.J. Stable has retained to race.

The online catalogue for the January sale is scheduled to be available Tuesday, Dec. 9.
