Princess Highway returns to Naas to defend her crown in the Group Three Irish Stallion Farms EBF Blue Wind Stakes.
Dermot Weld's charge landed this before going on to Ribblesdale glory at Royal Ascot, and though she struggled at the very top level after that, she is undoubtedly classy.
However, three-year-olds have won all of the last ten renewals of this contest and Jim Bolger's Rehn's Nest should relish the step up to a mile and a quarter, and she was a good winner in Group Three company at the Curragh.
Bolger also has strong claims in the opening Dragon Pulse EBF Fillies Maiden at 5.15 with Heart Focus, placed twice in two starts already this year.
That experience could give her the edge over Aidan O'Brien's Bye Bye Birdie, a 300,000 guineas purchase, and Dermot Weld's speedily-bred Elegant Peace.
O'Brien unleashes Fountain Of Youth in the Fishery Lane Race, and the 420,000 guinea son of Oasis Dream is sure to have his supporters, as will Bolger's Club Wexford.
Again, experience could count though, as Kevin Prendergast's Curragh fourth Saakhen may improve again.
O'Brien also has a newcomer in the Kill Maiden in the shape of Lake Nova, but this is a good opportunity for Resolute Response.
The Weld runner appeared in dire need of the experience when third at Tipperary last time and could shape a lot better.
Hanky Panky didn't make the cut for the French 1000 Guineas at the weekend, but she could gain some consolation in the Irish Stallion Farms EBF Fillies Maiden.
There's a big prize on offer for the Woodlands 100 Club Handicap and pits last-time-out winners Katchy Lady, Yulong Baoju, Scotland Forever and Ask Dad against the O'Brien-trained Vinson Massif and the Bolger inmate Wexford Opera, both second on their most recent runs.
