Quadrilateral will take on eight rivals in the Group One bet365 Fillies’ Mile at Newmarket, this Friday.
The Roger Charlton-trained daughter of Frankel stormed to an impressive success at Newbury last month, but now takes a massive leap in class.
Connections decided to supplement Quadrilateral – and the May Hill Stakes winner Powerful Breeze, has also been added at a cost of £40,000.
Aidan O’Brien has won the race five times before and relies on Moyglare Stud Stakes winner Love.
Jessica Harrington, successful in Sunday’s Prix Marcel Boussac with Albigna, trains the other Irish contender, the unbeaten Cayenne Pepper.
Harrington also trained Millisle to win the Group One Cheveley Park Stakes on the Rowley Mile, just under two weeks ago, so she is gunning for a remarkable hat-trick of Group One victories with three different juvenile fillies.
“We have always liked Cayenne Pepper and what she’s done is already on the board, she’s three-from-three, she’s won on good ground, she’s won on fast ground and she won with a bit of ease in the ground at The Curragh last time.
“I was delighted with her victory in the Flame Of Tara Stakes where she saw the mile out well. She made the running then and also on her previous start but she doesn’t have to lead.
“She’s a straightforward filly who is very laid back so I can’t imagine the travelling over to Newmarket would worry her and she’s a well-balanced individual who has won on a variety of tracks here in Ireland so the dip should not be a problem either.
“To win a third Group One in the space of a couple of weeks would be simply unbelievable.”
John Gosden fields one of the dark horses in the race in Anastarsia.
Ananya (Peter Chapple-Hyam), Boomer (Tom Dascombe), Queen Daenerys (Roger Varian) and West End Girl (Mark Johnston) complete the field.
Limato aims for a third successive win in the Group Two Godolphin Stud & Stable Staff Awards Challenge Stakes.
His four rivals include Lockinge Stakes winner Mustashry, not seen since finishing fifth in the Coral-Eclipse Stakes.
Shine So Bright was a course and distance winner in the European Free Handicap in April – and recently defeated Laurens in the Group Two City Of York Stakes. Oh This Is Us and Solar Gold complete the line-up.
Final Song, Stylistique and Vividly have all been declared in a nine-runner field for the Group 3 Godolphin Lifetime Care Oh So Sharp Stakes, while fourteen remain engaged in the opening Group 3 Cornwallis Stakes.
