A win for Wycombe Wanderers at Plymouth Argyle keeps Northampton ahead of the Devon club and now with two games in hand on their nearest rivals.
Defeat for Bristol Rovers at Accrington, meanwhile, means the gap between Town and the team in 4th remains at 11 points.
Next Saturday’s opponents, York City, had a morale-boosting 2-1 victory at home to Stevenage which draws them level on points with Dagenham & Redbridge at the foot of the table.
