[7] Daniel O'Rourke made his seasonal reappearance in the 2000 Guineas at Newmarket for which he was strongly fancied, starting second favourite at odds of 3/1.

[12] Daniel O'Rourke was then sent to Royal Ascot where he won the St James's Palace Stakes, beating Alcoran "cleverly" by a length, despite suffering an injury to his hip in the horse-box on the way to the course.

On 27 July he started 4/5 favourite for a Bentinck Memorial Stakes but ran very poorly behind Poodle and was pulled up in the closing stages although he crossed the line for third place ahead of Hobbie Noble, who had also been eased down to a walk.
