Landmark win for O’Brien in Cesarewitch

The younger brother of Joseph O’Brien, the 16-year-old had only ridden his first winner last month but defied his inexperience with a fine ride on his father Aidan’s five-year-old, running in the colours of his mother, Anne-Marie.
Burdened with top-weight, O’Brien’s 7lb claim proved invaluable as Hidden Universe and Pat Smullen pressed hard through the final furlong.
