Chris Hackett's fine solo effort helped Northampton on their way to victory over AFC Wimbledon.
Huw Johnson could have put the Dons ahead in the first half, but his header was saved well by Lee Nicholls.
The Cobblers went ahead when substitute Adebayo Akinfenwa fed through to Alex Nicholls, who fired in.
Then came Hackett's moment, as he picked up the ball from 40 yards out, eased past two defenders and slotted home to wrap up the win.
Northampton were without striker Jake Robinson, who has joined Luton Town on a one-month loan deal.
VIEW FROM THE DRESSING ROOM
Northampton Town manager Aidy Boothroyd told BBC Radio Northampton:
"It was a very tough game. If you're going to be successful, you've got to be persistent, and we're certainly that.
"The clean sheet is the most important thing for me. We're always going to score goals but I thought it was important we got that clean sheet and made our pressure count.
"We took probably 50 per cent of the chances that we created today."
AFC Wimbledon manager Terry Brown told BBC London 94.9:
"I was pleased with the first half of the performance. I thought we came out bright in the second half and looking to go up a gear.
"But the goal killed us. I am a bit disappointed that, when the goal went in, too many heads went down for my liking.
"Both goals were dire from a defensive point of view. Both goals were pretty horrendous.
"We created a few chances, but they created more chances than us."
