Conor Wilkinson’s double earned Chesterfield a first victory in five league games as they brought Northampton Town’s incredible 31-game unbeaten run to an end.
A goal in either half from Wilkinson, making his home debut after joining on deadline day, put the Spireites in a commanding position.
The Cobblers briefly threatened a comeback when Paul Anderson pulled a goal back shortly after the hour mark, but Kristian Dennis flicked Dion Donohue’s strike home twenty minutes from time to seal a 3-1 victory for the home side.
