Nicky Frost scored the only goal of the game as Wyberton kept their Lincolnshire League title ambitions alive at Cleethorpes Town Development Squad.
The narrow victory sees the Villagers remain third in the standings.
However, before last night’s fixtures they trailed leaders Skegness Town by six points and had two games in hand.
Gary Frost’s side have their destiny in their own hands as they still have top two Town and Sleaford Reserves to face.
But first they host sixth-placed Lincoln Railway Athletic at the Causeway on Saturday (KO 3pm) and travel to Skegness United next Wednesday (7pm).
