What's behind the intense O'Brien family feud at the Curragh Cup?

The iconic O'Brien dynasty is set to dominate the Curragh once again as father Aidan and son Joseph go head-to-head in a stellar renewal of the Group 2 Curragh Cup. Defending champion Al Riffa looks to secure back-to-back victories for the Joseph O'Brien stable, but he faces a formidable challenge from Aidan O'Brien's recent Royal Ascot winner Illinois. This high-stakes family rivalry has completely monopolised the staying contest over the last decade, making Sunday's showpiece a critical tactical battle.

What We Know So Far

The dominance of the O'Brien family in this particular fixture is unprecedented. Together, Aidan and Joseph O'Brien have been responsible for 11 of the last 13 winners of the Curragh Cup. Aidan claims eight victories from his Ballydoyle base, while Joseph has secured three from his Owning Hill yard. This race historically serves as a crucial springboard for international success, with Joseph previously using it to prep his Melbourne Cup heroes Rekindling in 2017 and Twilight Payment in 2020.

Last year's winner, Al Riffa, returns to his favourite hunting ground following a respectable fourth-place finish in the Ascot Gold Cup behind Scandinavia over an exhausting two-and-a-half-mile trip. Dropping back to a more suitable one-and-six-furlong distance, the six-year-old entire remains a formidable force under jockey Dylan Browne McMonagle. However, conditions at the track are expected to be faster than during his Irish St Leger triumph, which could alter the dynamic among the market leaders.

Aidan O'Brien counters exclusively with Illinois, a highly flexible five-year-old who bounced back from a disappointing Coronation Cup run to land a heavily supported victory in the Queen Alexandra Stakes at Royal Ascot just 14 days later. With stable jockey Ryan Moore expected to utilize prominent tactics from stall two, Illinois will likely attempt to turn the race into an authentic, grueling test of stamina from the front.

Al Riffa likes the Curragh and we're hoping for a good run. Tennessee Stud is progressing well and we think he's in for a good autumn, while Trustyourinstinct is a Curragh specialist and steps up in trip here. We think he has an each-way chance.
