< Jukebox Jury and Duncan fought out a pulsating finish to the Irish Field St Leger at the Curragh and the judge could not split the British pair at the end of the Classic.

Johnny Murtagh tried to lead all the way on the Mark Johnston-trained Jukebox Jury (4-1) and hot favourite Fame And Glory was one of the first beaten as they turned into the straight.

But Duncan (5-1) ranged up alongside a quarter of a mile out under Eddie Ahern and John Gosden's colt - stablemate of Doncaster St Leger hero Masked Marvel - played his part in a sustained duel to the line which resulted in a dead-heat.

Aidan O'Brien's top-class juvenile Power got back into the winning groove with a professional performance in the Goffs National Stakes.

Stablemate David Livingston went on from the start and had plenty in trouble entering the closing stages of the Group One contest as Seamie Heffernan readied Power for the attack.

The 11-4 shot led well inside the final furlong and was chased hard by favourite Dragon Pulse who could not quite get there and went down by half a length.

O'Brien introduced a two-year-old with plenty of potential in Imperial Monarch who strode away with the Loughwood Fencing EBF (C & G) Maiden to give Heffernan a double.< Born To Sea has a long way to go before he can bear comparison to his illustrious half-brothers Sea The Stars and Galileo, but he could hardly have made a better start as he took the Irish Field Blenheim Stakes.

Johnny Murtagh settled him in behind and once a gap came the John Oxx-trained youngster (5-2 favourite) darted through to claim the Listed race by a length and a half.

Oxx completed a double when Minsk (5-2 favourite) scooted away with the Curragh Amateur Derby Handicap by three and a half lengths under Katie Walsh.

Dermot Weld's juvenile Madhmoonah (7-2 joint-favourite) picked off newcomer Wading deep into the final furlong to take the Foleys Antiques Naas EBF Fillies Maiden by a length and a quarter under Pat Smullen.
