Aidan O'Brien's duo of Precise and Amelia Earhart will look to give the master of Ballydoyle yet another Epsom Oaks after they both stood tall following Saturday's confirmation stage.

Twelve horses remain in contention after the latest stage, with recent Irish 1000 Guineas heroine Precise now a distinct possibility to step up to a mile and a half to the first time having hit the line strong in the Curragh.

She looks set to be joined by impressive Cheshire Oaks scorer Amelia Earhart, with O'Brien also responsible for three other entrants, including Lingfield trial scorer Cameo, Beautify and Sugar Island.

John and Thady Gosden's well-bred Juddmonte filly Legacy Link catapulted herself into Classic contention with a cosy success in the Musidora Stakes at York. The daughter of Dubawi – who is out of Chiasma – making her a niece to the mighty Frankel, ended her juvenile campaign by finishing fourth behind Precise in the Fillies' Mile.

Speaking earlier in the week at a press event organised by the Jockey Club, John Gosden said: "They're a good bunch of fillies and it looks like it's an exciting Oaks, let alone an exciting Derby. You've got depth in the field in both, which is what it's all about.

"I think there's some other very nice fillies in there. The thing is, it's the beginning of June. Three-year-olds going a mile and a half the first time. The puzzle unlocks in front of you. But before the race, it's hard to be dogmatic, that's for sure.

"A lot of these fillies haven't truly come into bloom yet. You go and look at your gardens, same story."

Ralph Beckett may just run one according to recent reports, but he currently has three in contention, with Wathnan Racing's A La Prochaine still in the mix alongside K Sarra, who was third behind Legacy Link in the Musidora Stakes, and On Message.

Venetian Lace is all set to step up in distance after her excellent third in the 1000 Guineas at Newmarket, while Thundering On is in contention for Joseph O'Brien.

Andrew Balding currently has Prizeland engaged.
