Aidan O'Brien saddles potent trio in St Leger at Doncaster

Aidan O'Brien holds all the aces as Illinois, Jan Brueghel and Grosvenor Square bid to give him an eighth victory in the Betfred St Leger at Doncaster.

Successful with Continuous 12 months ago, the master of Ballydoyle has taken home the trophy for the world’s oldest Classic three times in the last 10 years.

Illinois is attempting to do what Leading Light (2013) and Kew Gardens (2018) have done in the past and follow up victory in the Queen’s Vase at Royal Ascot with Classic glory on Town Moor.

Last seen finishing a neck second to stablemate Los Angeles at York, he will be partnered by Wayne Lordan – who having twice won the 1000 Guineas on a Ballydoyle second string, now gets first pick with Ryan Moore required at Leopardstown.

O’Brien told the sponsors: "We’re very happy with him. We always thought he’d stay, he won at Ascot over a mile and six and he ran very well in the Voltigeur which we felt was a lovely trial for him.

"Wayne rode him that day and was very happy with him. Nice ground is important to him, he’s closely related to an Arc winner (Danedream) so he has a lot of class, we think and hope the Leger will suit him well. We would have run him in the Derby, but City Of Troy was there. We’ve had the Leger in mind for a long time for him."

Another rider picking up a big-race opportunity for O’Brien is Sean Levey who spent his formative years based with the Tipperary handler and has excelled this season for his primary boss Richard Hannon aboard Rosallion.

He has already steered Lake Victoria to Group-level success for Ballydoyle this season and now partners the unbeaten Jan Brueghel, who showed plenty of fight to grind out victory over Andrew Balding’s Nashville Derby hero Bellum Justum at Goodwood last month.
