Aidan O’Brien has landed today's Group Two Debutante Stakes (6.05) at the Curragh 12 times, but he may be denied the baker’s dozen by his son Joseph this time around.

The elder O'Brien saddles a pair of contenders in course and distance winner Concert Hall and Galway scorer Twinkle, but Agartha has a clear advantage in terms of experience on her sixth career start and Joseph can deny his father another success.

The Caravaggio filly saved the best for last when making all in the Group Three Silver Flash and she wasn't stopping at the line in Leopardstown so there's enough evidence to suggest that Declan McDonogh's mount may prove best in a top-class renewal.

With the €100,000 prize also carrying Alpha Centauri’s name, it would be fitting should her sister Discoveries land the odds for Jessica Harrington but Agartha is preferred.

Anything other than victory for the Aidan O'Brien-trained Point Lonsdale in the Group Two Futurity Stakes (6.40) would be a massive turn up for the books with the Australia colt already favourite for next year's English 2,000 Guineas as Ryan Moore's mount bids to make it four wins from four starts.

Such is the quality housed in stables across Ireland, there's rarely a weekend that passes where the country is not represented on the world stage and this one is no different.

All eyes will be on Deauville tomorrow as Gavin Cromwell's Royal Ascot winner Quick Suzy bids for Group One success in the Prix Morny (2.50) with Gary Carroll in the plate for one of the biggest rides of his career.

Moore also partners the unbeaten Velocidad after Joseph O'Brien's juvenile made it two from two when landing a Curragh Group Two in June while the Kilkenny trainer is also represented by Thundering Nights in the Jean Romanet (3.25).

The four-year-old delivered a career-best when edging out Santa Barbara in the Pretty Polly and Shane Crosse eyes another Group One in a red-hot affair where the Irish focus will also be on Willie McCreery's Insinuendo as well as Harrington's Cayenne Pepper.

Shane Foley partners Silence Please for Harrington in the Group Two Prix de Pomone (4.0) as well while the Kildare trainer will also be keeping a close on the US overnight as Soaring Sky tackles the Grade One Del Mar Oaks (2.0), although the Free Eagle filly faces a tough task at the Californian track.
