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.

Unlucky not to give Stags an early lead with deflected shot. Offered a decent attack option out wide in the wing-back role. Photo: UGC

Feeding on scraps at times and offered little threat before being subbed. Photo: UGC
11. Michael Smith - 6
Missed a great chance to level on 42 minutes after tamely shooting at the keeper before having one ruled out for an alleged foul on the keeper. Should have scored. Photo: Mansfield Town
12. David McGoldrick - 5 (Replaced Hendry at HT)
Showed a few bright moments after coming on but didn't have the impact Nigel Clough would have been looking for. Photo: Maynard Manyowa/Mansfield Town
