A first half goal from Antoni Sarcevic proved to be the difference between the two sides during a below-par first half from the visitors.
Stags did have a good chance to level with Michael Smith missing an excellent chance close to half-time.
Harry Lewis was the stand-out performer with a number of good saves to keep Stags in the game.

14. Elliott Hewitt - 6 (Replaced Knoyle 65)

15. Luke Bolton - 5 (Replaced Reed 66)
Was brought on for Reed to bring much-needed pace and creativity to Stags. Failed to deliver during an anonyous display. Photo: Chris Holloway
