In what Manager Steve King described his toughest week in the job, The Wings claimed a gritty 1-0 victory and moved up to 5th in the table.
Pre game all the talk on the terraces was of the reduction in budget that had been brought in during week but despite this quality still remains in this Welling squad and they showed this with a bright start.
Brendan Kiernan showed some good trickery but could only chip over the bar from an acute angle. However Eastbourne had a good chance shortly after countering a Welling corner, Charlie Walker crossed for Lloyd Dawes but he headed wide when perfectly placed.
A fine defence splitting ball from Bradley Goldberg sent Gavin McCallum into the area and after clever trickery he shot just over.
Ex-Wings player Ryan Hall then took a swipe at an effort that went wide.
New signing Jack Barham connected well with a Kiernan cross but he headed straight at the keeper.
A mazy run from Brendan Kiernan was brought to a sudden end by what looked liked a clumsy challenge however the referee saw it differently and booked Kiernan for simulation.
McCallum did well to pick out Goldberg who had a free shot on goal but he perhaps took a touch to many and although he got his shot away it was deflected for a corner. From the corner Thierry Audel headed over.
On the stroke of half Danny McNamara intercepted play and broke down the right wing but curled his shot just over the bar.
In a quiet opening to the second half Dawes had the first opportunity of the half as he hit a wild shot wide for the away side. Quigley then had a shot from range but that to went wide.
The superb Danny McNamara then had to be alert to prevent Eastbourne with a last ditch tackle.
Sensing his Wings side needed frehsieng up Steve King made a double substitution bringing on Montel Agyemang and Danny Mill and it made the difference. In the 73rd minute Welling made the breakthrough Mills made space which allowed Kiernan to burst his way into the area before he was fouled by Tom Gardiner and this time the ref pointed to the spot. Brendan Kiernan stepped up and sent Hawes the Borough keeper the wrong way to give Welling the lead.
Kristian Campbell sent in another long range effort as Eastbourne huffed and puffed trying to get back in the game.
Jack Barham produced a snap shot from close range that was well saved by Sam Howes.
But Welling only needed the one goal and saw out the 4 minutes of added time to end a tough week with 3 valaubale points.
Welling travel to Billericay Town next week in another crucial play off chasing encounter.
