Easthouses welcomed East Lothian side Dunbar to Newbattle Complex for the first time since they made the switch to the Juniors.
In the fifth minute Graeme Young nonchalantly toe poked the ball into the net with the Dunbar defence static.
Things got worse for Dunbar seven minutes later when Kevin Smith brought down Alexander Elliot on the edge of the box and the referee awarded a penalty kick which Paul McDermott duly dispatched into the net to give Easthouses a two goal lead.
Easthouses tails were up and Elliot and Russell both went close with efforts before Darren Gillon forced a good save out of the home keeper Steven Hay. Elliot again missed a good chance for Easthouses before a long ball from the Dunbar defence found Dean Ballantyne clear with only the keeper to beat but his shot struck the post before being cleared to safety.
Three minutes later and Dunbar were made to rue the missed chance when Elliot beat the Dunbar offside trap and squared to the back post where Young was lurking and the big striker fired a low shot sweetly into the bottom corner to make it 3-0.
Two minutes after the restart a Chris King free kick was headed into the path of Chris Moffat by Grant and the midfielder wasted no time before blasting the ball high into the net to give the visitors a lifeline in the game at 3-1 .
Minutes later the Seasiders’ Darren Gillon found Dean Ballantyne with a great diagonal pass but the youngster shot inches wide with only the keeper to beat.
Easthouses scored again on the break with a cross from the right finding Young at the back post and he fired home for his hat trick to make it 4-1.
Barry Hogg headed a free kick over with the home defence static and Steven Kean fired over from the edge of the box. But Dunbar’s day was probably best summed up in the 78th minute when Dean Ballantyne twisted away from his marker inside the box forcing Hay into a great save but the rebound struck the legs of a Lily defender and fell straight into the arms of keeper Hay.
Deep into injury time the United pressure finally paid dividends when the hard working Chris Grant squared for Darren Handling to fire home from the narrowest of angles and put a better reflection on the scoreline at 4-2.
