Grimsby Borough Academy 0-1 Horncastle Town (Papworth)
Despite starting the game the brighter of the two sides, Grimsby Borough were unable to capitalise, and Horncastle's Liam Papworth struck a sweet 25 yard volley on the 23rd minute mark to give his side a 1-0 lead.
Both teams had plenty of opportunities took score the 2nd goal of the game, but none were taken as the Wongers held onto their slim advantage to lift the Supplementary Cup.
The league would like to thank Sleaford Town for their hospitality on the evening.
The Wongers play Immingham Town in the final of the Challenge Cup at Brigg on Friday, whilst Grimsby Borough look to pick themselves up as they travel to The Causeway to play Wyberton on Saturday.
