Nitrogen

Nitrogen began her career as a 2-year-old with a runner-up finish in a Woodbine one-mile maiden race on the turf on Aug. 30, 2024. She then placed third as a maiden in the Grade 1 Natalma Stakes at Woodbine on Sept. 14 and finished her juvenile season with another third-place finish when still a maiden in the Breeders' Cup Filly and Mare Juvenile Turf.

Nitrogen finally got her overdue maiden win in her first outing as a 3-year-old in a one-mile grass race at Gulfstream Park on Jan. 4, 2025. She was immediately back versus stakes company after that for her next start, which came in the Grade 3 $200,000 Florida Oaks at Tampa Bay Downs on March 8. Sent off as the 3-2 favorite in an 11-horse field in the Florida Oaks, Nitrogen stalked the pace up close, challenged the leader in deep stretch and got up in time for a half-length victory.

In her next start, Nitrogen was sent off as the 6-5 post-time favorite in the Grade 2 Appalachian Stakes Presented by Japan Racing Association April 8 at Keeneland. She took over at will entering the stretch of the 1 1/16-mile turf race to win by 2 ¼ lengths over stablemate and Grade 3 winner Vixen. The bay filly by Medaglia d'Oro followed with a runaway 3 ½-length victory as the odds-on favorite in the $600,000 Edgewood Stakes presented by Accenture on the May 2 Longines Kentucky Oaks undercard at Churchill Downs. 

Nitrogen’s next start came in the Wonder Again Stakes June 7 at Saratoga on the Belmont Stakes Presented by NYRA Bets undercard. The race was switched from turf to dirt and held at one mile due to heavy rain earlier in the Saratoga Springs region, and featured only three horses after scratches. In her first start on dirt, heavy favorite Nitrogen romped over the sloppy track to win by 17 lengths geared down by jockey Jose Ortiz.

Bred in Kentucky, Nitrogen is out of the stakes-placed Uncle Mo mare Tiffany Case and is a half-sister to stakes winner Love to Shop.
