Aidan O’Brien has declared his two big guns, Yeats and Scorpion, in a bid to win the Irish Field St Leger for the first time at the Curragh on Saturday.
A field of nine is set to line-up for the all-aged Group One over a mile and three-quarters.
Yeats has tasted defeat in the last two runnings of this race, being only fourth to Collier Hill two years ago and second to Kastoria when long odds-on last September.
However, he is unbeaten in three starts this year culminating in back-to-back victories in the Gold Cup at Royal Ascot.
Scorpion, winner of this summer’s Coronation Cup, has not tackled this distance since landing the St Leger at Doncaster in 2005.
The home team is completed by Kevin Prendergast’s Mores Wells, Dermot Weld’s Bellamy Cay and Galistic, trained by Pat Flynn.
Geoff Wragg’s veteran The Whistling Teal bids to make it third time lucky at the age of 11, having been second to Collier Hill in 2005 and third behind Kastoria 12 months ago.
Three other British-trained horses – George Moore’s Macorville, Jane Chapple-Hyam’s Mighty and Steppe Dancer, from Denis Coakley’s stable – make up the nine.
