Matt Pennington scored the game’s only goal in the second half. Here are our player ratings from Sixfields...
5. Harvey Lintott
Started the game promisingly and made one or two dangerous forays forward from wing-back but was less effective in the second half, though did go close with a late chance... 6.5 Photo: Pete Norton
6. Patrick Brough
Barely troubled defensively but opportunities to get forward were extremely limited and he was hooked at the break... 6 Photo: Pete Norton
7. Jack Sowerby
Got through plenty of good work out of possession as his discipline at the base of midfield blocked passing lanes and stopped Blackpool from playing through Cobblers, but couldn't make much headway going the other way... 6.5 Photo: Pete Norton
8. Shaun McWilliams
Better energy and tempo about his play than in previous outings and he did not stop trying to make something happen, even if little came off... 6.5 Photo: Pete Norton
