Siskin heads a final field of 11 declared for the Tattersalls Irish 2,000 Guineas at the Curragh on Friday.

The unbeaten Ger Lyons-trained colt progressed from his debut success at Naas in May to land a Listed race at the Curragh before picking up the Group Two Railway Stakes and then the Group One Phoenix Stakes.

He had been due to run in the Middle Park at Newmarket, but became unruly in the stalls and was withdrawn.

Aidan O’Brien leads the opposition with a team of six – Armory, Fort Myers, Lope Y Fernandez, Monarch Of Egypt, Royal Lytham and Vatican City.

Mick Halford is represented by Sinawann, who was last seen finishing second to Mogul in Group Two company on Irish Champions Weekend, while Jessica Harrington calls on the unexposed Leopardstown maiden winner Free Solo.

Jim Bolger runs the once-raced Fiscal Rules, whose only outing as a juvenile was a head second to Qipco 2000 Guineas runner-up Wichita at the Curragh in August.

Andrew Slattery’s Rebel Tale, second to Armory in the Futurity Stakes and two places behind Sinawann at Leopardstown, completes the line-up.
