Marquand and Kirby join Moore and Dettori on Ballydoyle's 2,000 Guineas squad

Tom Marquand and Adam Kirby will join Ryan Moore and Frankie Dettori on the Ballydoyle team sheet on Saturday after all four were paired with runners trained by Aidan O'Brien in the Qipco 2,000 Guineas.

A final field of 15 was declared on Wednesday for the first Classic of the season, with champion two-year-old Pinatubo heading the market at a general 5-6 favourite.

As anticipated, Moore rides second favourite Arizona, winner of last year's Coventry Stakes at Royal Ascot, with Dettori booked for Wichita.

Marquand, fresh from top-level success with Addeybb in Australia when racing in Britain was suspended, has been called up for Royal Dornoch, while Kirby will be aboard outsider New World Tapestry.

"I know Arizona did very well at two, but we always thought he would make up into a better three-year-old," said O'Brien. "The ground should be ideal, as the better the ground, the better he will be. We're very happy with him at the moment."

Although beaten twice by Pinatubo last season, Arizona has been strong in the ante-post Guineas market and was a general 11-2 chance after the final field was revealed.

O'Brien added: "He's quite a fast horse, certainly not short of pace. We're not sure whether he will stay beyond a mile, although we might try him over a bit further at some stage."

Priced between 10-1 and 14-1, Wichita appears to be the stable's second string and last year's Group 3 Tattersalls Stakes winner will have the assistance of Dettori for the first time.

"Wichita is a powerful, straightforward colt with a really good attitude," said O'Brien. "He's very versatile with regard to ground and I do think he will stay further than a mile. He seems very well."

Dettori will also have his first ride since the resumption of racing for his former employers Godolphin when he partners Terebellum in the Dahlia Stakes (2.25) earlier on the card.

Marquand takes his first ride for O'Brien on Royal Dornoch, a general 33-1 chance who defeated another of Saturday's rivals, Kameko, to land the Group 2 Royal Lodge Stakes at two.

The jockey said: "I don't think there are many jockeys who don't dream of riding in Classics for the Ballydoyle team and Aidan O'Brien, and I'm honoured to be given the ride. He's carrying some really good course form, beating Kameko in the Royal Lodge from last year, so fingers crossed."

O'Brien added: "Royal Dornoch was a good juvenile and we were thrilled with him in the Royal Lodge. We're not sure whether he will get much further than a mile. He's in good form."

New World Tapestry, an 80-1 chance with Betway and bet365, completes the trainer's quartet, with Kirby riding the son of War Front for the first time.

O'Brien said: "New World Tapestry would look to have a bit to find with some of the main contenders but seems in good form."

Favourite Pinatubo, the mount of William Buick, will break from stall seven, with Arizona in stall 13 and the well-fancied Kameko in 15.

Pinatubo will be putting a six-race unbeaten record and sky-high reputation on the line and his trainer Charlie Appleby gave the thumbs up to his preparation on Wednesday.

"He's done everything right," said Appleby. "I'm very happy with him. He's eating, drinking and looking well. I wouldn't change my script about him from 12 months ago – he just goes out and gets the job done. I can't fault him."
