The Mariners took another giant step towards Football League survival as they beat Swindon Town at the County Ground to claim their first away win since November.
Again, Mitch Rose was the hero as his penalty in first-half stoppage time proved to be the only goal of the game.
Town saw out the game from then on, defending well when needed and creating chances to add to their lead.
And although results elsewhere meant the Mariners are not yet mathematically safe from relegation, they stay five points clear of Barnet with two games to go in the battle to beat the drop to the National League.
