Vodafone Derby favourite Yeats is set to make his seasonal reappearance at Leopardstown on Sunday as part of a card which should provide Classic clues aplenty.
The Aidan O'Brien-trained colt shot to favouritism for the race following an easy four-length debut success at the Curragh on his sole outing as a juvenile.
The son of Sadler's Wells features among 13 entries for the FPW McGrath Memorial Ballysax Stakes, a race which the Ballydoyle trainer successfully used to launch the three-year-old campaigns of his previous Derby winners, Galileo and High Chaparral.
The 10-furlong event has also attracted two Richard Hannon-trained entries in Fantastic View and Psychiatrist, although the former is declared to run in the bet365 Craven Stakes at Newmarket on Thursday.
Dermot Weld's Grey Swallow, meanwhile, is second favourite behind O'Brien's One Cool Cat for the UltimateBet.com 2000 Guineas and is one of eight entries for the Leopardstown 2000 Guineas Trial Stakes over a mile.
Weld could also be represented by Medicinal, while O'Brien's possibles are Meath and Tumblebrutus, the latter a full-brother to Giant's Causeway but who has yet to show he is anywhere near as good as his sibling.
A total of 15 fillies are entered in the 1000 Guineas Trial, including O'Brien's Last Love, Lucky and Royal Tigress.
