5/2 Sir Dragonet leads O’Brien trio - (2026)

Jockey Donnacha O’Brien says Sir Dragonet is the one to watch as Aidan O’Brien prepares to send three horses to the St Leger at Doncaster on Saturday (Sir Dragonet 5/2 to win).

Eight horses have been supplemented for Saturday’s feature race, with John Gosden’s Logician the favourite at odds of 10/11.

O’Brien also sends Il Paradiso and rank outsider Western Australia to Yorkshire this weekend.

Western Australia is as big as 50/1 to win this weekend after he finished outside the places in his last three runs.

The three-year-old won at Navan in May and will need to produce a career-best performance to secure victory.

At odds of 7/1, Il Paradiso cannot be ruled out and the chestnut colt has been in good form since July.

He won at the Curragh before finishing third at York in the Weatherbys Hamilton Lonsdale Cup Stakes.

Donnacha claims Sir Dragonet is still the one to beat and he has claimed Logician also needs to “improve” to stand a chance of beating his ride.

He told Racing TV: “I think he’s a nice horse but he’s going to have to improve to run to my level of form. My lad is the one to beat.

“I ride him [Sir Dragonet] in all his work [and] he’s absolutely flying at home. He gives a very good feel and I’m right looking forward to it.

“It’s always an unknown when you step up in distance but he looks to have every chance of staying. It’s an unknown for plenty of horses in the race but I think he goes there with a big chance.”

Mark Johnston sends Sir Ron Priestley and Nayef Road to Doncaster, while Technician and Dashing Willoughby complete the field.
