Chris Broe fired a five-under-par 68 - the course was a combination of the front nine and the new nine — to capture the top prize in the RaboDirect sponsored Hilary Golf Society outing at Portmarnock Golf Club.
The current captain of Beech Park Golf Club was a model of consistency, carding 14 pars, two bogeys and two birdies in a testing wind.
Athy's Jonathan Kelly (3) captured the runner-up prize with a 69 while Royal Dublin's Liam Hutchinson (1) shot 73 to claim the gross prize.
In the team competition, Broe and Hutchinson were joined by Portmarnock's John Greene (Plus 1) and St Anne's Paul Behan (1) in posting a winning score of 61.
The final outing of the season and prize presentation takes place at The Royal Dublin on Friday next April 7.
