Keith Curle's men have now claimed 16 points out of the past 18 available to them, and have moved up to fifth place in the table.
The performance in the win over the managerless Mariners was far from a pretty one, but it proved to effective and that is what counts.
So which players shone as the rain poured down at Sixfields?
Take a look at what our man Jeremy Casey thought with his match ratings...
1. David Cornell
Made crucial stops, one in each half, from Matt Green and James Hanson, and never put a foot wrong the whole game... 7.5 | Getty
2. Sam Hoskins
Nobody can ever question Hoskins' work-rate and he again put in a shift. But he didn't get any change out of left-back Lewis Gibson all game... 6.5 | Getty
3. Charlie Goode
Another gigantic performance from skipper Goode. Rock solid in defence, and always willing to rampage forward in attack... 7.5 | Getty
4. Jordan Turnbull
An integral part of what is becoming a seriously strong back three. Won virtually every header, and rarely beaten on the deck... 7.5 | Getty
