Royal Dublin's Brendan O'Malley won the RaboDirect sponsored Hilary Golf Society outing at Laytown and Bettystown.
The three-handicapper returned a fine 69, beating fellow Royal Dublin member Hugh Foley (scratch) by a shot.
Foley finished with three straight birdies but despite his storming finish, he came up just short.
County Louth's Gerard Dunne (plus 2), the runner-up in last year's East of Ireland Championship, claimed the gross prize with an excellent two-under-par 69.
The team prize went to Portmarnock's John Greene (plus 1) and five handicappers John Hutchinson from Royal Dublin and Martin Kelly from Forrest Little with a 12 under par 59.
The next outing takes place at County Louth Golf Club, Baltray, on Sunday, March 26
