Rizeena finished strongly in the hands of James Doyle to claim Group One honours in the Moyglare Stud Stakes at the Curragh.
Winner of the Queen Mary at Royal Ascot before being placed in Newmarket's Duchess of Cambridge Stakes and the Prix Morny at Deauville, Clive Brittain's filly was a 9-2 shot for her latest assignment.
Given plenty of time to find her feet by Doyle, she was produced late and showed a smart turn of foot to swamp her rivals in the final furlong.
Rizeena's fellow British raider Kiyoshi, so impressive in the Albany Stakes at Royal Ascot despite hanging across the track, once again showed wayward tendencies.
Charlie Hills' charge quickened up well to take the lead, but hung across rivals in the closing stages and passed the post second.
The previously unbeaten Tapestry did not enjoy the clearest of runs, but finished strongly just behind the front pair in third.
The stewards immediately called an inquiry.
After a lengthy inquiry the stewards decided to reverse the placings of Tapestry and Kiyoshi with Aidan O'Brien's Tapestry promoted to second.
