Aidan O’Brien is responsible for seven of the 14 entries in the Derrinstown Stud Derby Trial at Leopardstown on Sunday.

The Co Tipperary handler has saddled a remarkable 11 previous winners of this prestigious contest, with subsequent Epsom Derby heroes Galileo (2001) and High Chaparral (2002) joined on the roll of honour by other Ballydoyle greats such as Yeats (2004) and Dylan Thomas (2006).

This year’s potential squad includes Japan – who is a general 6-1 shot for the Investec Derby at Epsom on June 1st – Anthony Van Dyck and impressive Ballysax Stakes victor Broome.

Blenheim Palace, Sovereign, Turnberry Isle and Western Australia complete the Ballydoyle septet.

Joseph O’Brien has course scorer Buckhurst and Grandmaster Flash in the mix, while Jim Bolger has entered Guaranteed and Copia Verborum.

The potential field is completed by Dermot Weld’s pair of Asdaa and Rakan and the Ger Lyons-trained Pythion.

Last seasons’s Derrinstown victor Hazapour is the potential star attraction in the Comer Group International Amethyst Stakes.

Weld’s charge went on to finish fifth at Epsom and his comeback run in the Alleged Stakes at Naas last month was not devoid of promise.

He is among 11 entries for this for the one-mile Group 3, with the William Haggas-trained Addeybb the highest-rated contender.

He could be joined on the trip from Britain by David O’Meara’s Suedois – a previous winner of the Boomerang Stakes over this course and distance – while Aidan O’Brien has two chances in Amedeo Modigliani and Dunkirk Harbour.

The middle of three Group 3s on the card is Derrinstown Stud 1,000 Guineas Trial.

Likely players include Weld’s Titanium Sky, the Mick Halford-trained Hamariyna and Beau Warrior – a five-times winner at Dundalk for Ado McGuinness.
