Aidan O'Brien will bid to create history at Epsom on a day when the English Oaks will be the curtain-raiser to the Derby, but domestically Naas will host a trial for the Irish Oaks in which O'Brien will rely on Laburnum.
However, it is Even So (5.15, Naas), which is a rare runner for Coolmore's John Magnier from the Ger Lyons stable, that is picked to oblige here and book her place in the next Curragh Classic.
The daughter of Camelot was fifth in the Irish 1,000 Guineas when last seen and the step up to 10 furlongs here should see her return to winning ways under Colin Keane.
Naas stages a fascinating card which will feature live on RTÉ this evening and the concluding contest will see a British raider make the journey across the Irish Sea which has been something of a rarity since racing returned.
The Classics in Ireland were for natives only, but Tim Easterby is sending over the progressive Art Power (5.45, Naas) for the Group Three Lacken Stakes.
The Royal Ascot winner landed some confident bets when running away with the Palace Of Holyroodhouse Handicap last month and he most certainly earned his right to a step up to Group Three class here.
Few trainers have come out of lockdown in better form than Johnny Murtagh, who runs Koolasice here, while Jessica Harrington's outstanding filly from last year Millisle will be hoping to break her duck for this season in a race that carries plenty of depth.
However, Art Power should end what could be a very profitable day for former champion jockey Keane.
Just the five runners go to post for the opening of three pattern races on the Naas card, but Sussex Garden (2.30, Naas) can add to her course-and-distance win just over a fortnight ago.
Harrington introduced Alpha Centauri to win at Naas a few seasons back and then returned to win this Group Three event, and that path may prove fruitful once again for the Moone maestro.
Sussex Garden made a similarly good impression when winning on her racecourse debut and can continue the fine run of Shane Foley, a jockey who himself could be eyeing up a possible first championship tilt.
Meanwhile, jumps racing returns to Bellewstown today where the Fast Shipping Bellewstown Handicap Hurdle is worth a tasty €40,000.
Confidence in the market surrounding Poseidon would be significant, but Zarkareva (5.30, Bellewstown) is a tentative choice. The French import was tried in a juvenile Grade Two event at Christmas, albeit well beaten.
Given the way she was campaigned on her two starts for Henry de Bromhead, she could be a filly that is capable of running above her rating of 118 and is worth a look.
The Eoin Doyle-trained Stylish Moment (5.0, Bellewstown) is a horse we might not have seen the best of yet and could be a step or two ahead of the handicapper and be value here.
Fairyhouse and Cork stage all-Flat cards tomorrow with the Munster Oaks taking centre stage in Mallow.
Search For A Song (5.15, Cork) needs to concede weight all round but looks a cut above her rivals for Dermot Weld and Oisín Orr.
In the earlier Marble Hill Stakes, Shalaalaa (3.05, Cork) might continue a fine weekend for Lyons and Keane.
There is Group Three action at Fairyhouse also where last weekend's Curragh winner Speak In Colours (5.30, Fairyhouse) would seem the standard setter if he can stay the trip.
