Aidan O'Brien, whose Was finished second in the featured Pretty Polly Stakes, enjoyed a Curragh treble, highlighted by victory for Beach Of Falesa, ridden by his daughter, Sarah, in the Ladies' Derby.

The top weight, running in the colours of the winning jockey's mother, Anne-Marie, cut down Eighteen Summers late on to score by two lengths.

The most eyecatching performance of the day was put up by the O'Brien-trained Ernest Hemingway on his step up to a mile and three-quarters for the At The Races Curragh Cup (Group Three).

Seamie Heffernan's mount (12-1) had plenty to do at the two pole but sprouted wings and shot past his rivals to collar Royal Diamond inside the final furlong and win going away by five lengths.

O'Brien's juvenile Bye Bye Birdie (9-2) disappointed at Royal Ascot, but she put that well behind her with an all-the-way success in a first-time visor in the Grangecon Stud Stakes (Group Three) under Joseph O'Brien, beating favourite Heart Focus by three lengths.

The much-touted Ballydoyle newcomer Australia, a son of the brilliant Ouija Board, was an unlucky loser in the Barronstown Stud EBF (C & G) Maiden as he was left four lengths but flashed home to finish a neck behind Jim Bolger's Renaissance Art (10-1).

Sabrina Harty's Ansgar (20-1) forged clear to win the Irish Field Handicap by two and a half lengths, while Mick Halford landed a double through the impressive Dabadiyan (5-2 favourite) in the Irish Stallion Farms EBF 'Ragusa' Handicap and Eastern Rules (6-1) in the O'Briens Wines Handicap.
