Lambourn led throughout when galloping his 17 rivals into submission in the Group One Epsom Derby (2,405m) earlier this month and he is the favourite to prove that was no fluke in Sunday’s 10-runner Group One Irish Derby (2,400m) at the Curragh.

If the son of 2014 Irish Derby winner Australia achieves that feat, he will be the 20th horse to land the historic Classic double as well as being an extraordinary 17th Irish Derby victor for his trainer Aidan O’Brien.

Ryan Moore takes over on Lambourn with Wayne Lordan, the triumphant winning rider at Epsom, partnering Puppet Master, who looks the strongest of O’Brien’s four other contenders.

What happens in the great Epsom Classic has traditionally proved the strongest guide to what occurs at the Curragh a few weeks later so it is no surprise to see Lambourn – drawn in gate five – taken on again by Epsom second and third, Lazy Griff and Tennessee Stud.

While Tennessee Stud has four and three-quarter lengths to find on Lambourn, he did best of those coming from off the speed at Epsom.

Also among Lambourn’s opponents are two colts owned by the Hong Kong-based Marc Chan - Green Impact and Sir Dinadan.

The Irish Derby is one of nine races the Jockey Club will offer for betting from the Curragh on Sunday night, while the simulcast programme also features two races from Saint-Cloud in France.

The pick of those is the Group One Grand Prix de Saint-Cloud (2,400m), in which Calandagan chases an elusive elite-level breakthrough at his fifth attempt.

The Francis-Henri Graffard-trained gelding has produced top-notch performances at this level in his past four outings, but on each occasion has come off second best.

“He’s a very talented horse and I’m sure he’ll win a Group One as he always runs his race,” Graffard said.
