Medaglia d’Oro, one of the most influential sires of the modern era, died Friday at Jonabell Farm in Kentucky at age 27. A son of El Prado, he raced for owner Edmund Gann and Hall of Fame trainer Bobby Frankel, winning eight of 17 starts and more than $5.7 million. His victories included the Grade 1 Travers at 3, the Grade 1 Whitney Handicap at 4 and the Grade 1 Donn Handicap at 5. He also ran second in the Group 1 Dubai World Cup and in back-to-back editions of the Breeders’ Cup Classic.

Medaglia d’Oro’s legacy at stud is extraordinary, encompassing 110 graded-stakes wins, over $104 million in total earnings and 9,633 starts across his crops. The sire of 31 Grade 1 winners, Medaglia d’Oro’s top runners include Eclipse champions Rachel Alexandra, Songbird and Nitrogen, three-time Hong Kong Horse of the Year Golden Sixty and a record three Kentucky Oaks winners: Rachel Alexandra, Plum Pretty and Good Cheer.
