Speaking afterwards, Moore said "He's a very good horse, he's an Irish Derby victor and a Group 2-winning two-year-old as well".

Aidan O'Brien continued his march towards a new record for Group One winners in a calendar year here on Saturday as Capri, the Irish Derby victor, stayed on strongly throughout the final quarter-mile to win the William Hill St Leger at Doncaster, the final Classic of the British season.

However the grey Capri had enough left in the tank to see off his rivals and took the honours after a battle down the straight by half a length from Crystal Ocean, with Stradivarius only a short head's distance back in third.

Capri became the first horse since Nijinsky in 1970 to win both the Irish Derby and the St Leger.

Stradivarius, the victor of the Group 1 Goodwood Cup against older horses at two miles in August, finished third, a short head behind Crystal Ocean.

The race favourite, trained by Aidan O'Brien, got the better of runner-up Crystal Ocean and third-placed Stradivarius earning Moore his first success in the world's oldest Classic to complete his set of victories in the British Classics. "He's done very little wrong in his career and has progressed from race to race", said Moore. "Everything had every chance, but he fought them off and was the best horse".

"He's a horse with a lot of class, which we saw in the Irish Derby", he said. "When Ryan really wanted him to, he gave it to him. I was a bit anxious about that as well, but it all went great".

Capri was cut to 20-1 from 25-1 for the Arc and 16-1 from 20-1 with RaceBets.
