The Irish League claimed a deserved victory in the representative game at Mourneview Park on Tuesday night.
Goalscorer Paul McAreavey holds off Craig Stanley
Gary Hamilton's flicked header gave the Irish side a 16th minute lead and Paul McAreavey headed in five minutes later to make it 2-0 to the hosts.
The Conference's Steve Morison saw his 39th minute penalty saved by Alan Mannus and the Irish went further ahead through David Scullion on 58 minutes.
Paul Benson's strike eight minutes later proved merely a consolation.
McAreavey's whipped cross set up Hamilton for the opener before the Linfield midfielder doubled the lead after connecting with a Scullion corner.
Referee Mark Courtenay awarded the spot-kick for a handball by McAreavey and Morison's failure to find the net was the decisive moment of the game.
A good move involving Richard Clarke and Michael Halliday ended with Dungannon Swifts midfielder David Scullion rifling home the third from 20 yards.
Dagenham & Redbridge player Benson gave the English non-league side hope as he outpaced David McAlinden before lifting the ball beyond substitute keeper Elliott Morris.
But the Irish League looked the more likely to score in the final stages with visiting keeper Danny Alcock blocking shots from Conor Downey and Scullion.
