I doubt Ruler of the World will be anywhere near Town Moor on the day of the year’s final classic. As a Derby winner, Coolmore will now gear the rest of his career to creating a strong stallion prospect. After the Irish Derby, they will look to capture a Group I over 10 furlongs. With his pedigree, out of Galileo and a half to Duke of Marmalade he will prove a very attractive stallion prospect. That being said, I would expect him to remain in training at four, given that the Duke did his best work that season.
