Aidan O’Brien is delighted with Sir Dragonet ahead of the son of Camelot returning to action for the first time since the Investec Derby in the Royal Whip Stakes at the Curragh today.

Sir Dragonet was only beaten three-quarters of a length when fifth to stablemate Anthony Van Dyck in the Epsom Classic, on only his third career start, after leading the field two furlongs from home.

He had gone to the Derby unbeaten and on the back of an eight-length romp in the Chester Vase.

O’Brien feels the time is right to get Sir Dragonet back on the track and drop him down in trip to a mile and a quarter for the first time.

The Ballydoyle handler is using this Group Three contest as a stepping-stone for Sir Dragonet to bigger targets.

“I’m very happy with Sir Dragonet,” said O’Brien.

“Mentally and physically he is very good and the plan is to run in the Royal Whip and then on for either the Irish Champion Stakes or Prix Niel.”

Sir Dragonet was among seven declared, with rivals including Buckhurst trained by Joseph O’Brien and winner of the Group Three International Stakes over the course and distance seven weeks ago.

Jessica Harrington is hoping Leo De Fury has better luck than he endured at Goodwood, where he did not enjoy the best of runs when unplaced behind Nayef Road in the Gordon Stakes. The Australia colt had won his only two previous starts in promising fashion.

“He had a bit of problem when he knocked around a bit in Goodwood,” said Harrington.

“He came out of the race fine and we’re taking the next step.

“With Aidan’s one in there, a very highly-rated colt in Sir Dragonet, we’ll have to see what we do.”
