New York Thoroughbred Breeders Inc. highlights the impressive performance of Slumber, a stallion with a standout strike rate in the Empire State. In their Stallion Spotlight series, Rockridge Stud’s Erin Robinson shares insights about Slumber, a Grade 1 winner and sire of the Grade 2 millionaire Fluffy Socks.
Slumber, a bay horse born in 2008 by Cacique out of Is Sleeping (Woodman), boasts a race record of 27 starts with 5 wins, 6 places, and 5 shows, earning $1,477,162. His advertising fee is set at $7,500.
When asked what makes Slumber appealing to breeders, Robinson points to his impressive strike rates—18.2% black-type winners and 27.3% black-type horses from runners in 2024, surpassing many Kentucky stallions, including Vekoma, which has 16.5%. For mares needing conformation improvement, Slumber offers a broad genetic range he consistently passes to his offspring. Robinson emphasizes that mares with a turf pedigree, particularly those from the El Prado sire line like Kitten’s Joy and Medaliadro, seem especially compatible.
Looking ahead, with Belmont Park planning to add an all-weather track for winter racing, Robinson believes Slumber and fellow stallion Wardancer will become mainstays for turf and all-weather racing in the Northeast. Notably, Slumber’s turf runners average a race distance of 1 1/16 miles—the longest among New York sires—which fills a niche for breeding two-turn turf horses, a market currently underserved despite demand for such progeny in top-grade races and broodmare sales.
Slumber’s standout progeny, Fluffy Socks, a multiple Grade 2 winner and millionaire, validates his ability to produce top-class runners. Robinson mentions several promising young runners including Coach Case, Mr. Bless, Gilben, and stakes-winning trio Jack and Jim, who indicate Slumber’s growing influence.
Although Slumber’s pedigree is European, his female line includes strong dirt performers like Slew o’Gold, and while his offspring mainly excel on turf, there may be some dirt aptitude emerging as his progeny matures.
Robinson concludes with a breeder-focused message, emphasizing personalized guidance to optimize mare improvement and sales outcomes, underscoring her commitment to breeder success.
