Frankie Dettori teams up with Aidan O'Brien's Navy Seal in Beresford Stakes

Frankie Dettori teams up with Aidan O'Brien’s Navy Seal as the trainer looks to regain the Alan Smurfit Memorial Beresford Stakes at the Curragh.

When Crypto Force beat O’Brien’s Adelaide River in the race 12 months ago, it was the first time the Ballydoyle handler had suffered a defeat in the Group Two since Casamento won for Michael Halford in 2010.

Among his incredible 21 winners of the race are St Nicholas Abbey, Capri, Saxon Warrior and Luxembourg, but the most famous winner on the roll of honour is John Oxx’s brilliant Sea The Stars in 2008.

The trainer has had to look away from usual jockey Ryan Moore this weekend as he is in Australia to partner Shinzo for owners Coolmore in the Golden Rose at Rosehill.

O’Brien has three strong contenders this year in Leopardstown winner Chief Little Rock (Gavin Ryan), Galway debut winner Grosvenor Square (Colin Keane) and Dettori’s mount Navy Seal, who stepped up markedly on his debut fifth at Killarney to win at Galway.

"Chief Little Rock came forward nicely to win at Leopardstown but he only just won, we thought he’d win easier than he did but he won anyway," said O’Brien.

"He’s in good form and we think he’s a horse who is going to progress more. He’s got a stout pedigree and will be staying well next year.

"Grosvenor Square won nicely at Galway, that was only 11 days ago. He’s a lovely, big horse but he was babyish and green there, so we think the experience will do him well. He’s another with plenty of stamina in his pedigree.

"Frankie is riding Navy Seal for us. He won nicely at Galway the last day but he was a little but green.

"He ended up winning nicely at the end and we think he’s ready to go again. The first day we were a bit disappointed, we expected him to run better but he
