Seven Ballydoyle runners headed by the unbeaten 2000 Guineas winner Saxon Warrior, are still engaged in the Investec Derby at Epsom on Saturday week.

Delano Roosevelt, The Pentagon, Rostropovich, Zabriskie, Kew Gardens and Nelson make up the septet of the 16 runners remaining in the mile and a half classic.

Saxon Warrior, a son of Japanese stallion sensation Deep Impact is the 8/11 market leader with Unibet, official betting partner of the Investec Derby Festival, as he bids to become just the third horse this century to complete the QIPCO 2000 Guineas/Investec Derby double after Sea The Stars (2009) and Camelot (2012).

Delano Roosevelt and The Pentagon, had to settle for minor honours behind Hazapour (Dermot Weld) in a bunched finish to the Group 3 Derrinstown Stud Derby Trial at Leopardstown on May 13th.

Rostropovich, winner of the Listed Dee Stakes at Chester, Listed Lingfield Derby Trial second Kew Gardens, Group 3 Ballysax Stakes winner Nelson and Dante Stakes third Zabriskie complete the O'Brien acceptors as the trainer chases a record-equalling seventh Investec Derby victory.
