Oh Say, a Maryland stallion and before that one of the many stars in the racing stable of the late Jane du Pont Lunger's Christiana Stable, was euthanized in late July because of complications from the infirmities of old age. He stood at the Rooney family's Shamrock Farms near Woodbine."He suffered from a tumor in the sinus area and was growing a little senile," said bloodstock consultant Don Litz, who managed the 24-year-old son of Hoist the Flag for a number of years.Oh Say won seven of nine races, but his greatest claim to fame came when jockey Bill Shoemaker raved about the horse to trainer Henry Clark. The Hall of Fame rider, who was scheduled to ride Christiana's grade I winner Linkage in the 1982 Preakness Stakes (gr. I), rode Oh Say to an eight-length win earlier on the undercard."Henry Clark told me that right after Oh Say's race, Shoemaker told him that Oh Say was the better horse," recalled Litz. (Linkage ran well in the Preakness, but couldn't catch front runner Aloma's Ruler.)Oh Say, who was produced from the grade II-winning Cyane mare Light Hearted, won the 1982 Hannibal Handicap and earned $78,543 in his short racing career. He entered stud at E.P. Taylor's Windfields Farm in Maryland and stood at other farms before ending up at Shamrock.Oh Say has sired 25 stakes winners, including grade I winner Sham Say, and was ranked among Maryland's leading sires a number of years. His other stakes winners include grade III winner Balotta and a Chilean champion and Panamanian champion. He is represented by the earners of $16 million.
