Ian Sampson will have been delighted to see the response of his side to having gone a goal down early on before Beckwith and McKenzie struck to ensure a vital three points.
The Cobblers climb out of the bottom two as a result and ease the pressure hugely on their manager who warned this week that livelihoods were on the line for both himself and his players.
A 'relieved and happy' Sampson told the official club website after the game: 'We weren't at our best but we decided to go a bit more direct and I think it worked.'
With the manager warning that a relegation battle remains his current focus, 21st-placed Northampton will now look to move away from the bottom with a win at Lincoln City, currently 22nd in the table, on Tuesday night.
