Clontarf professional Eamonn Brady and European Tour regular Damien McGrane shared first prize at the Shell Pro-Am at Carne Golf Links.
The result continues a remarkable run of form for Brady who has now racked up five victories in PGA in Ireland events this summer.
“I hit it great on Saturday, missed only one green but I struggled a bit today (Sunday),” said Eamonn who will play in Monday's Regional Qualifying event for The Open at The Island (see field).
“I dropped a few shots coming in and thought maybe I had blown it but I did just enough to hang on to match Damien.”
The players battled cold, damp conditions all weekend at the 36-hole event with winds gusting to around 40mph at one stage on Sunday.
Brady led after round one, following a fine two under par round of 69 on Saturday but Sunday's two-over 73 opened the door for the rest of the field.
His nearest rival after the opening round, Killarney's Daniel Sugrue couldn't manage to bridge the gap, following up Saturday's opening round of 70 with a 73.
McGrane was two shots behind after an opening 71 and, starting at the 10th, he went to the turn in one under 35. The European Tour regular gave himself chances over the closing nine holes but could not find another birdie and a bogey five at his final hole ultimately cost him outright victory.
