Lambourn emulated his sire, Australia, by completing the Epsom Derby-Dubai Duty Free Irish Derby double, and in doing so became the twentieth horse to have his name emblazoned on both rolls of honour.

For his trainer, Aidan O'Brien, who is the most successful in both races, it was a remarkable 17th win in this race, and for jockey Ryan Moore, it was a third — all in the last three years.
