Ryan Moore will partner the hugely talented So You Think in the Tattersalls Gold Cup at the Curragh on Sunday.
The Australian import enjoyed a spectacular career Down Under, winning multiple Group One contests and signing off with an excellent third in the Melbourne Cup.
He barely came off the bridle on his first start for Aidan O'Brien in the Mooresbridge Stakes and returns to the highest level this weekend.
Seamie Heffernan guided him to that impressive debut on Irish soil but Moore, who has teamed up to good effect with team Ballydoyle already this season, takes over in the saddle at the weekend.
Trainer Aidan O'Brien's wife Anne-Marie said on her Twitter page: "Ryan Moore confirmed for So You Think on Sunday."
