An impressive winner of the Ribblesdale Stakes at Royal Ascot last month, the daughter of Mastercraftsman is trainer Aidan O’Brien’s chief hope of claiming a fifth success in the mile-and-a-half Classic following the previous victories of Alexandrova (2006), Peeping Fawn (2007), Moonstone (2008) and Bracelet (2014).
The master of Ballydoyle also saddles Munster Oaks winner Pretty Perfect and Epsom Oaks fourth and sixth Somehow and Seventh Heaven.
Hugo Palmer struck gold 12 months ago with Covert Love and is this year double-handed with Architecture and We Are Ninety.
Architecture ran a fantastic race to fill the runner-up spot behind the brilliant Minding at Epsom, but disappointed in the Ribblesdale.
We Are Ninety was a couple of places ahead of her stablemate when sixth in the same Royal Ascot contest.
A strong British contingent is completed by Mick Channon’s Epsom Oaks third Harlequeen and the Roger Varian-trained Ribblesdale second Ajman Princess.
The Jim Bolger-trained pair of Turret Rocks and An Cailin Orga, the John Oxx-trained Red Stars and Way To My Heart from Joseph O’Brien’s stable complete the field.
Meanwhile, Breeders’ Cup winner Hit It A Bomb will not make his return to action this weekend.
Aidan O’Brien’s lightly-raced three-year-old had been in line to have his first start since his win at Keeneland in October in the Friarstown Stud Minstrel Stakes at the Curragh on Sunday.
But O’Brien said: “He’s good. He’s in on Sunday, but he won’t run.
“He’s done very well since his break, but he’ll take a day away before he runs.”
The War Front colt struck Grade One gold in the Juvenile Turf in America, after winning at the Curragh on his debut before following up in Listed company at Dundalk.
