The high-powered trio of Ballyliffin's Damian Mooney, Drive Golf Performance Ltd's Colm Moriarty and Kilkenny's Jimmy Bolger shared first prize at the Luttrellstown Pro-Am on Monday.
All three returned scores of five under par 67 to finish two shots ahead of Headfort's Brendan McGovern, Ashbourne's John Dwyer and Old Conna's Neil O'Briain.
The leading trio amassed a total of 21 birdies on a day of low scoring at the Castleknock venue.
Brendan McGovern, who fired a course record round of 62 to win the PGA Tankard at Royal Tara last week, recorded an albatross at the par five 12th.
Jimmy Bolger and amateur partners claimed the team prize with 93 points.
