The William Haggas-trained pair of Beshaayir and One Master head a small but select field of six for the Tattersalls Falmouth Stakes at Newmarket on Friday.
One Master is already a Group One winner, having lifted the Prix de la Foret at Longchamp in October and she was only beaten a length when third in the Queen Anne Stakes at Royal Ascot.
Beshaayir steps up to the top level on the back of a Group Two success at the Curragh on her seasonal debut and is the mount of Frankie Dettori.
I Can Fly, who was beaten a length and a half by that filly in the Lanwades Stud Stakes, is Aidan O’Brien’s sole representative after the Ballydoyle trainer took out Happen at the 48-hour final declaration stage.
Roger Varian is responsible for the two three-year-olds in the line-up – the 1000 Guineas third Qabala and Mot Juste.
Veracious, trained by Sir Michael Stoute, completes the sextet.
Royal Ascot winners Raffle Prize and Daahyeh feature among a field of seven for the Group Two Duchess of Cambridge Stakes.
The Mark Johnston-trained Raffle Prize will bid to follow-up her victory in the Queen Mary Stakes while Daahyeh, from the Varian stable, will attempt to take her 100 per cent record to three after landing the Albany Stakes.
Ken Condon’s Celtic Beauty, who was beaten a length and a half by Daahyeh that day, is the only Irish-trained hopeful.
Saeed bin Suroor’s Final Song, third in the Queen Mary, is one of two Godolphin runners along with the Charlie Appleby-trained Divine Spirit.
David Simcock’s Bredenbury and Archie Watson’s Lambeth Walk make up the seven.
