Lustown Baba ran her best race of the season so far when a narrow second to Snapraeterea in the Owenstown Stud Stakes at Naas on her latest outing and her trainer is hopeful of another bold showing – provided the ground is suitable.
McCreery said: “You’d hope she’d run a big race. We had soft ground, but we’re after having two beautiful days here and she does need a bit of cut in the ground.
“There’s meant to be a few local thunder showers tomorrow, so hopefully we get a few of them.
“She’s in good shape. You’d just love the ground to be on the soft side for her.”
The Rathbride handler also saddles Star In The Making in the six-furlong Group Three contest. She is rated 11lb inferior to her stablemate.
“She’s got to improve and we’re just hunting for black type for her,” McCreery added.
“She’s a very honest filly and I think six furlongs is her trip.”
The likely favourite is Paddy Twomey’s Sonaiyla, who is also a dual Curragh winner and has never finished out of the first three in six previous appearances at the track.
The daughter of Dark Angel was beaten just a length into third in the Group One Flying Five Stakes last autumn and can be expected to improve from her comeback third in the Greenlands Stakes less than a fortnight ago.
Other hopefuls include Ken Condon’s Thunder Beauty – last seen finishing down the field in the 1000 Guineas at Newmarket – and her stable companion Teresa Mendoza.

Aidan O’Brien is represented by Lough Derg, who has has finished behind the yard’s Derby favourite Bolshoi Ballet on his last couple of appearances. Donnacha O’Brien runs Nicest, who was last seen finishing third in the Cheshire Oaks.
