Aidan O'Brien became the first trainer to win the Irish Derby three years in a row after Frozen Fire claimed a surprise win at The Curragh on Sunday.

Jockey Seamus Heffernan timed his run to perfection as the 16-1 chance came through the field with a furlong to go.

After a stewards' inquiry, favourite Tartan Bearer was promoted to third place with Casual Conquest in second.

O'Brien's victory was his sixth in the race, bringing him level with legendary namesake Vincent O'Brien.

"It's unbelievable," said Aiden O'Brien, who won the race with Dylan Thomas in 2006 and Soldier Of Fortune last year.

"We always thought this horse had a lot of class and Seamus gave him a very good ride.

"This is down to a lot of people - it's been a privilege to have been involved in it.

"Seamus has worked very hard and is a great judge of a horse. Nobody deserves it more than Seamus and I couldn't be happier for him.

"This is marvellous. The race was a full, solid mile-and-a-half and there are no excuses.

"All of ours have run great races, but I think Alessandro Volta got stage-fright when he turned into the straight - he wouldn't have seen a crowd like that in front of him before.

"The Curragh is probably the greatest racecourse in the world as it is a very fair track and really tests a horse."

Ante-post favourite New Approach was withdrawn on the morning of the race with a bruised foot, denying Jim-Bolger's horse the chance to become the first to complete the English-Irish Derby double since 2002.
