It was a disappointing performance from Jon Brady’s men, who never truly got to grips with an impressive home team.
Vale were full of running, energy and attacking invention, pinging the ball around with confidence, with Brady admitting his team was ‘suffocated’.
Alfie Devine, Oliver Arblaster and the impressive Funso Ojo were at the heart everything the home side did, and although the Cobblers defended well and limited the amount of clear-cut chances, they were eventually worn down.
Substitute Ben Garrity was the man to break the deadlock, firing home a 20-yard strike five minutes from time.
Town were left to rue Sam Hoskins passing up their best chance just a matter of minutes earlier, but in truth the home side deserved their victory.
