Aidan O'Brien unleashes another potential Classic contender in the shape of Giant's Causeway at the Curragh on Sunday.
The unbeaten colt faces 10 rivals in the Group Three Castlemartin/La Louviere Studs Gladness Stakes.
The son of Storm Cat, a 9-2 chance for the Sagitta 2000 Guineas with William Hill, won three races last season culminating in a two-length victory in the Group One Prix de la Salamandre at Longchamp.
His rivals include the Dermot Weld-trained Tarry Flynn, a four-time winner last season including the Group Three Coolmore Stud Home Of Champions Concorde Stakes at Cork.
