Sky Jack (foaled April 18, 1996 in California) is a retired American thoroughbred racehorse. Background Bred and raced by Rene and Margie Lambert, he was sired by Jaklin Klugman and out of the mare Sky Captive, a daughter of the 1986 Breeders' Cup Classic winner Skywalker. Racing career After a successful season in 2000, Sky Jack incurred a knee injury that required multiple surgeries. In addition, he suffered from bouts of colic, all of which kept him out of racing until September 2002. Having recovered from life-threatening illnesses, the gelding enjoyed his most successful season, winning the Grade II Mervyn Leroy Handicap and the Grade I Hollywood Gold Cup. In winning the 2003 Longacres Mile Handicap, Sky Jack set the record for both the fastest time and widest margin of victory. Retirement Due to a recurring knee problem, Sky Jack was retired in November 2003 to his owners' farm near Temecula, California. Suffering from malignant melanoma, on June 30, 2016 Sky Jack was humanely euthanized.
