Geneticists have yet to come up with a scientific explanation of what makes a sire of sires. And while it may be tempting to view the phenomenon as a man-made construct with no genetic basis, that explanation, too, remains unconvincing, at least for the most extreme cases.

Some of New York racing’s biggest stars won’t be in action Saturday on Empire Showcase Day at Belmont Park, but the reason why is a nice problem for the state’s Thoroughbred industry to have.

New York-breds have had a phenomenally successful year racing against open company, and a handful of the program’s best are eyeing the Breeders’ Cup at Santa Anita on Oct. 31 and Nov. 1.

The growth of New York’s breeding sector in recent years has been no secret and is one of the clear success stories within a Thoroughbred industry that is finally reaching a stable economic plateau after a slow recovery from the 2008 recession. As a result, the Empire State has become a viable destination for young stallions who possess both accomplished race records and quality pedigrees.

West Virginia has become known in recent years as a hotbed for sustained runs of dominance.

Rapid Redux earned a Special Eclipse Award for his record-setting 22-race winning streak, with a significant portion of those victories coming at Mountaineer and Charles Town. Meanwhile, local hero Russell Road has been a force on the West Virginia stakes circuit for seven years, claiming just about every statebred award laid before him.

Stallions Tiz Wonderful and Any Given Saturday have been sold to Korean interests to stand in that country beginning in 2015.

Tiz Wonderful, a 10-year-old son of Tiznow previously stood at Spendthrift Farm in Lexington, Ky., where he was advertised for a fee of $7,500 during the 2014 breeding season. He debuted at stud in 2009.

"We received an offer that we thought was more than fair from the Korean Racing Authority, and acted on it," said Spendthrift Farm general manager Ned Toffey.

The Australian High Court denied former bookmaker-turned-breeder Bruce McHugh a special leave to appeal on Friday, ending his bid to allow Thoroughbreds conceived by artificial insemination into the country’s breed registry.

Revolutionary, winner of last year’s Grade 2 Louisiana Derby and this year’s Grade 3 Pimlico Special, has been retired from racing by owner WinStar Farm and will stand at the Versailles, Ky., farm in 2015 for an advertised fee of $7,500.

The 4-year-old son of War Pass will participate in WinStar’s “Dream Big” program, which offers breeders an opportunity to earn a lifetime breeding right in the stallion after their matings produce two live foals from his first books.

Grade 1 winner and sire El Corredor has been purchased by Tevfik Celikoglu of Turkey to stand in 2015.

The 17-year-old son of Mr. Greeley previously stood at the Stallion Station at Copper Crowne in Opelousas, La., where he stood the 2014 breeding season for $3,500.

Uncaptured, Canada’s 2012 Horse of the Year, will make his stallion debut during the 2015 season at Ocala Stud in Ocala, Fla. A stud fee will be announced at a later time.

The 4-year-old son of Lion Heart won 7 of 18 career starts for earnings of $1,065,147. He was named Canada’s champion 2-year-old and Horse of the Year during his juvenile campaign, in which he won the Grade 2 Kentucky Jockey Club Stakes and Grade 3 Iroquois Stakes at Churchill Downs and the Swynford Stakes, Clarendon Stakes and Vandal Stakes at Woodbine.

There will be no changes in advertised stud fees for the stallion roster at Darby Dan Farm in Lexington, Ky., for the 2015 breeding season.

Preakness Stakes winner Shackleford will once again lead the way among the Darby Dan stallions with an advertised fee of $20,000. The 7-year-old son of Forestry is represented by his first crop of weanlings in 2014, and his first weanling to sell at auction brought $150,000 at the recent Fasig-Tipton Saratoga fall mixed sale.
