Deire Na Sli from the Jim Bolger yard landed the seven furlong nursery handicap at Leopardstown in good style by three lengths to pick up a 13,000 euro prize in the hands of Kevin Manning.
The filly's sire, Aussie Rules, was a former winner of the French 2000 Guineas and she appeared to relish the soft ground encountered.
Bolger said: "She ran a bit freely with the blinkers on last time so we left them off today and it worked well."
The winner was returned at 8/1 and had drifted at the track from an opening show of 9/2. Madeira Man finished second at 11/2 and front-running Independent Girl faded to third at 20/1. Nucals Star was the 2/1 favourite and finished eighth.
