An early goal from debutant Joe Lamplough set The Bulls on their way but they had to wait for the 52nd minute to double their lead.
This came from Man of the Match Glyn Cotton who fired in a low driven free kick from 20 yards.
After this Grimsby's opposition crumbled, debutant Chris Wood pounced on indecision at the back to put AFC Mansfield 3-0 up.
Another quality strike from Cotton made it 4 before Tristan Whitman made it 5-0 with an excellent finish to seal the match.
The Bulls move up to 3rd in the league, the chase is on!!!!
