The Philadelphia enjoyed a promotion party after coming from behind to rescue a 2-2 draw against Wingate Cons.
The sides went into the game level on points, but Phili crucially having a superior goal difference, meaning the visitors had to win to claim the third promotion spot in Division Three.
Phili enjoyed the perfect start, going ahead in the second minute when Alan Jones unleashed a left-footed shot which beat the keeper and crept in the left corner of the net.
Wingate levelled just before half-time, with Paul Bestford latching on to a long goal kick and placed his shot past the advancing keeper.
Terrence Wright quickly doubled the agony for The Philadelphia, picking up a loose ball on the edge of the area and thumping home a fierce shot.
Phili changed formation to try to save the game, but Wingate looked like holding out and even went close to a killer third goal, onlyu for home keeper Brian Teasdale to pull off two magnificent saves.
A series of free-kicks tested Wingate’s goalie, but the visiting defence stood firm until a minute from time when they failed to clear an Andrew Bainbridge set piece and Mickey Grieves was on hand to ram the ball home from eight yards to seal promotion.
