The Montjeu colt was sent to the front two furlongs out by Seamus Heffernan to beat fellow newcomer Copper Bell by three lengths, with a 13 lengths gap back to Basalt in third.

The American-bred colt galloped clear inside the final quarter mile and Burke could afford to take things easy in the closing stages to beat Jeu De Roseau by two lengths.
'He jumped out well and Robbie said he was happy making it. He's an honest horse and if he's okay will probably go for a seven furlongs nursery at Leopardstown,' said trainer Robbie Osborne.
Attercliffe made it two wins from as many starts when readily justifying odds of 8/11 in the concluding ten furlongs winners race.
