Brian Boru, trained by Ballydoyle maestro Aidan O'Brien and ridden by Jamie Spencer, won the Seabiscuit St Leger Stakes at Doncaster this afternoon.

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.

DONCASTER have announced a link-up with Hollywood in a one-off sponsorship deal for next month’s St Leger.
