Goals in each half from Kevin Thornton and sub Michael Jacobs earned Northampton a 2-0 win against Stockport - only their fourth home victory of the season.
Recalled to the starting line-up, Thornton gave Northampton the perfect start with a fourth-minute goal, cutting inside two defenders before beating goalkeeper Matt Glennon with a neat finish.
Cobblers had two penalty appeals turned down when Leon McKenzie and John Johnson went down in the box, and Stockport made the most of the let off to work their way into the game.
Anthony Pulis fired wide at the near post and Greg Tansey tested Chris Dunn.
Northampton picked up the tempo again in the second half as Thornton saw a shot turned around the post by Glennon and from the ensuing corner, Abdul Osman saw his header deflected over.
Jacobs secured the points in the 75th minute when McKenzie set him free in the box and he curled the ball around Glennon from a tight angle.
The unmarked George Donnelly missed a great chance to reduce the arrears a minute later, but Northampton almost added a third when Glennon saved from McKenzie and Jacobs struck the upright from the rebound.
