The Pilgrims accounted for AFC Rushden and Diamonds courtesy of four first half goals at Rushden and Higham’s Hayden Road ground.
Maison North handed the Pilgrims the perfect start with a first minute goal and further strikes from Jordan Tate, Liam Adams and George Hobbins sealed a potentially season-defining victory, with one point now required from their final two fixtures to guarantee the title.
