O'Brien for a classic strike with Boru

Aidan O’Brien’s three-year-olds have come to the boil at just the right time to challenge for the big late-season prizes and the champion trainer has a great chance of Classic glory with Brian Boru in the Seabiscuit St Leger Stakes at Doncaster next month.

Ante-post punters should note that Brian Boru is a 9-2 chance with the Tote and William Hill and he looks well worth a bet at those odds after his close second to stable companion Powerscourt in the Daily Telegraph Great Voltigeur Stakes – the principal trial for the final Classic of the season.
