Finsceal Beo will join an elite club if she can add tomorrow's French 1,000 Guineas to her Newmarket triumph just six days ago, and victory at Longchamp will also set her up for a stab at history.
Just three fillies, Ravinella (1988), Miesque (1987) and Imprudence (1947), have completed the English-French 1,000 Guineas double, but none has collected the Irish version to complete a unique Guineas Triple Crown.
Considering the injury misfortune that has ruined Teofilo's Triple Crown hopes, such an achievement would be even more significant for the Jim Bolger team, whose high opinion of Finsceal Beo was justified in style last weekend.
Travelling beautifully throughout, the Michael Ryan-owned filly was not all out to beat Arch Swing, and among the significant comments afterwards were some that indicated Finsceal Beo is likely to improve for the run.
If she does, and if this quick reappearance doesn't take its toll, then her 12 opponents in the Poule d'Essai des Pouliches face a stiff task in halting Finsceal Beo's progress towards her own piece of racing history at the Curragh at the end of the month.
Darjina, the impressive Prix la Grotte winner, could be the one to press the Irish filly hardest.
Creachadoir represents the Bolger-Kevin Manning team in the 2,000 Guineas, the Poule d'Essai des Poulains, and the double Group Three winner is part of a remarkable, six-strong Irish team that also includes David Wachman's Followmyfootsteps and four runners from Aidan O'Brien's yard.
Ballydoyle's former number one, Jamie Spencer, teams up with the ex-Neville Callaghan-trained Excellent Art, while Gerald Mosse is on the supplementary entry, Honoured Guest.
Only four home-trained colts make a 14-strong field that includes four British-trained runners.
Charlie Swan sends Emmpat to Haydock today to try to complete a big-money hat-trick in the £75,000 Swinton Handicap Hurdle. Quick ground is essential for David Casey's mount, who returned to action with a bang at Fairyhouse last month and followed up in a prestige contest at Ayr.
