( CNN ) -- Aiden O'Brien 's superstar colt Camelot added the Irish Derby Saturday to his 2,000 Guineas and English Derby victories earlier this year . Ridden by his trainer 's teenage son Joseph , the unbeaten son of Montjeu was doubtful for the showpiece Curragh clash because of the soft ground . But O'Brien 's decision to run him paid off as he triumphed over Born To Sea . Camelot stormed to success in the English Derby earlier this month to put him in contention to become the first horse since Nijinsky to capture the English 'Triple Crown ' of Thoroughbred racing : the 2,000 Guineas , the Epsom Derby and the St Leger Stakes . The legendary Nijinsky also won the Irish Derby en route to his historic treble in 1970 . Camelot eyes horse racing immortality . O'Brien 's gamble of running Camelot looked in doubt when Born To Sea mounted a strong challenge , but the colt dug deep to pull two lengths clear and give the trainer his seventh successive victory in the race . Camelot is also the first horse since High Chaparral in 2002 to complete the Epsom-Curragh Derby double . `` We really felt it was n't the right thing ( to run on this ground ) but he 's a great horse , '' O'Brien told gathered reporters . `` It does n't get any better than this . These are days you ca n't dream of . He had the speed to win the Guineas , the class to win the Derby and then he had to have class , courage and stamina to win today . `` Obviously the lads will speak about the Triple Crown now , would n't it be something to dream about ? '' Bookmakers have already installed Camelot as a 1-3 favorite for the final leg of the Triple Crown at Doncaster .
