Course specialist Conor O’Rourke finished with three birdies to card a one-under 70 and claim the nett prize in the Tuesday Winter Series outing at Portmarnock Hotel and Golf Links.
Having recently turned professional, the 26-year old from Naas continued his run of good form at the Bernhard Langer designed links and maintained his 100 percent strike rate in this year's TaylorMade sponsored series by winning his second prize in as many starts.
Despite facing the remnants of Hurricane Ophelia, a 70-strong field teed it up and O'Rourke won the nett by two strokes from Castle two-handicapper Tommy Smith (72) with Malahide's Niall Carbery third with a 74.
County Louth's Enda Maguire made fives birdies in a level par 71 to win the gross by three strokes from Castle's Robert Moran, who played brilliantly before suffering a triple bogey seven at the 18th for a 74, edging out Royal Dublin Hugh Foley for second on countback.
