Rachel Alexandra retired from thoroughbred racing in September and was sent to Stonestreet Farm in Lexington, Kentucky, for breeding with Curlin.
“The breeding of these two singular athletes is the culmination of two equine racing careers without precedent,” Jess Jackson, major owner of both horses, said in an e-mailed statement. “We have been anticipating this introduction for some time now. Imagine what possibilities those two super horses might produce.”
Jackson is founder and owner of the Kendall-Jackson Wine Estates.
Rachel Alexandra went undefeated in 2009, including a 20 1/2-length win in the Kentucky Oaks and then a victory in the Preakness, the second event in racing’s Triple Crown. Jackson bought her after the Kentucky Oaks victory.
Rachel Alexandra opened 2010 with two runner-up finishes before claiming the Fleur De Lis Handicap and the Lady’s Secret Stakes. She finished second in the Personal Ensign Stakes on Aug. 29, her final race.
Curlin in 2008 became the first thoroughbred since Cigar in 1996 to retain Horse of the Year honors. He won 11 of 16 starts in two years and amassed $10.5 million in prize money, capturing the 2007 Breeders’ Cup Classic and the Preakness.
