Ashley Fletcher opened the scoring at Sixfield on the 20-minute mark, heading home a Rob Apter cross from close-range.
The striker was among a number of players to miss huge opportunities in the 2-1 defeat to Leyton Orient seven days prior, and would’ve been delighted to find the back of the net on this occasion.
It was a similar story for Niall Ennis – who doubled the Seasiders’ advantage after an hour. The Stoke City loanee did well to win the ball inside the Cobblers half, before beating Lee Burge with a shot off the inside of the post.
Here’s how the Seasiders performed:
