The Ballyroan Stakes takes centre stage at Leopardstown on Thursday evening and Aidan O'Brien is double-handed in his bid to land the Group Three prize for the second year running.
The Ballydoyle handler won the prize with Ernest Hemmingway 12 months ago and this year saddles El Salvador and Eye Of The Storm.
The latter, a dual Listed winner last season, is the choice of the trainer's son, Joseph, while his daughter Ana rides El Salvador, who was fourth in a competitive Galway handicap latest.
The O'Brien pair are unlikely to have it all their own way with Roheryn bidding for a hat-trick after a narrow Listed success here from Streetcar To Stars, who has subsequently won well at the Curragh and can continue to progress as he bids to reverse the form.
Jim Bolger's consistence Chance To Dance completes the quintet.
O'Brien takes the wraps of the well-bred A Greater Force in the closing Live At Leopardstown (QR) Maiden.
A full brother to French Group One winners Corre Caminos and Recital, the son of Montjeu cost €525,000 and a big run will be expected on his belated debut.
His stablemate, Illusive, attempts to build on a decent fourth here last time when stepping up in trip in the Foxrock Maiden, but Rightway will be no pushover having shown ability in two placed efforts to date.
Vert De Grece was narrowly held on his debut here in a maiden that has worked out very well and he is sure to have plenty of supporters in the Irish Stallion Farms EBF Maiden, which gets the seven-race card underway at 5.10.
California Rose is knocking on the door and bids to defy top weight in the Leopardstown Summer Membership Handicap, while Texas Rock also has to concede weight all round in the 'Johnny Marr' Handicap and the Rock Of Gibraltar colt has scope for further progress after opening his account off 2lb lower recently.
