A high-class card at the Curragh is likely to provide plenty of pointers for the future, with the two juvenile Group Twos starting with the Debutante Stakes for fillies.
Aidan O'Brien has won five of the last 10 runnings of the race, including with Yorkshire Oaks heroine Tapestry last year, and the trainer's son Joseph has opted to ride Dundalk scorer Qualify over I Am Beautiful and Toogoodtobetrue.
Quality opposition abounds, though, with Lucida having made a favourable impression on her debut and Beach Belle also a classy sort, while British raider Tigrilla can't be dismissed either.
O'Brien runs Gleneagles in the other juvenile Group Two, the Galileo EBF Futurity Stakes, and he is likely to be a warm order following his Tyros Stakes success.
Jim Bolger has won this with Teofilo and New Approach in the past, though, and his two runners are both of interest, with Hall Of Fame a full-brother to Dewhurst Stakes winner Parish Hall, while Kevin Manning rides Godolphin's Parish Boy, who beat the smart Order Of St George at Leopardstown last time.
Parish Hall has to concede weight all round in the Kilfrush Stud Royal Whip Stakes, and his task is made even more tricky by the presence of O'Brien's duo Hall Of Mirrors and Kingsbarns, while Edelmira and Magnolia Beach are hardly there simply to make up the numbers.
The Palmerstown House Estate Irish St Leger Trial is the final Pattern race on the card and sees Leading Light, the battling Gold Cup winner at Ascot, take on a former Irish St Leger winner in Royal Diamond, while the unexposed Streetcar To Stars is an interesting potential fly in the ointment.
The meeting kicks off at 2.25pm with the Luke And Nellie Comer Memorial Handicap, which sees Oor Jock, Local Flier, Elusive Ice and Greek Canyon all attempt to follow up recent successes.
