Doyoun dies

Doyoun, winner of the 1988 2000 Guineas and sire of the brilliant Daylami, has died, it has been announced on the Thoroughbred Times website.

The 17-year-old son of Mill Reef, who was at stud in Turkey, died on Thursday at Veliefendi equine hospital in Istanbul after suffering from an undisclosed health problem for nearly a month.

An autopsy was scheduled to determine the cause of death.

Doyoun had stood since 1999 at the Turkish Jockey Club's Izmit Pension Stud Farm located approximately 60 miles southeast of Istanbul.

He had previously been at the Aga Khan's Gilltown Stud in Ireland from 1989 to 1998.

Bred by the Aga Khan, Doyoun won three of seven starts and finished third in the Derby and the Champion Stakes.

Doyoun was trained by Sir Michael Stoute and ridden in all his races by Walter Swinburn.

He has so far sired 31 stakes winners in 11 crops of racing age and his progeny have earned US 16,590,483 in prize money.

In addition to Daylami, who won the 1999 Eclipse Stakes and the King George VI And Queen Elizabeth Diamond Stakes and Breeders' Cup Turf in 1999 for Godolphin, he also sired Kalanisi, who took the Champion Stakes and Breeders' Cup Turf in 2000.

Daylami won the Eclipse Award as champion turf male and was a Horse of the Year finalist in 1999 after an emphatic victory in the Breeders' Cup Turf at Gulfstream Park.

He also won the 1998 French 2000 Guineas, Man o' War Stakes, and the 1999 Coronation Cup. He retired with 11 wins in 21 career starts for $4,614,762 in earnings.
