Goals from Omar Bogle and Scott Vernon earned Grimsby a 2-0 victory in their Sky Bet League Two clash with Notts County.
It was a one-sided affair in terms of chances created, as the Mariners won at home for only the second time since the end of September.
Ahead of kick-off, midfield duo Jamey Osborne and Chris Clements were handed their debuts after signing for Grimsby in midweek.
And both of them had a hand in Grimsby's opener, which Bogle turned neatly into the far corner with his left foot.
As the first half drew to a close, muted appeals for a home penalty were waved away, as wing-back Zak Mills took a tumble.
Upon the restart, Danny Andrew and Mills both went close in quick succession, and at the other end, Richard Duffy headed agonisingly wide.
As the clock ticked by, Vernon tapped into the net, after Mills had crashed against the post, to seal all three points.
It means Grimsby have now won four of their last six league games.
