Great Heavens, ridden by William Buick, showed a tremendous turn of foot to take a convincing victory in the Group One Irish Oaks at the Curragh.
The 5-4 favourite is owned by Lady Rothschild and trained by John Gosden, who is enjoying a successful summer.
Shirocco Star (7-1), ridden by Johnny Murtagh, finished second of the seven runners, with Princess Highway (9-4), ridden by Pat Smullen, third.
Shirocco Star and Was led early on, before Great Heavens hit the front.
Once in the clear from two furlongs out, Great Heavens picked up in tremendous style to continue her rapid improvement this season.
