Castleknock's Paul Coughlan made six birdies in a five-under 66 to win the gross by three shots from Damien McGrane in the TaylorMade sponsored Tuesday Winter Series at Portmarnock Hotel and Golf Links.
After making three birdies in his first four holes, Coughlan was six-under par playing the 18th and still won comfortably despite finishing with a bogey.
McGrane started with three birdies and turned in four under par before finishing with bogeys at the 16th and 17th.
He was still second in the gross with a 69 as former East of Ireland winner Richie O'Donovan, now playing out of Dun Laoghaire, was third with a 70.
There were many other excellent performances on a fine day at the Bernhard Langer-designed links with only a warm southerly breeze to trouble the 80-strong field.
Europro Tour regular Brian Casey made his fifth birdie of the day at the 18th to shoot 68 and win the nett on a countback from Gary Cullen with County Louth four-handicapper Billy Gavin taking third with a 69 (gross 73) that featured two birdies on the back nine.
Cullen, who was also in the prizes last week, had two birdies and an eagle at the sixth in his round.
Irish Professional champion Tim Rice finished with three threes — birdie, par, birdie — but missed out on the prizes on countback.
