Northampton boss Jon Brady hailed a perfect away showing from his side as they ran out deserved 2-0 winners at Exeter.
Sam Hoskins ran through to open the scoring in the 20th minute before Patrick Brough sealed victory in stoppage time, ending a run of three consecutive League One defeats.
The Cobblers could easily have been bigger winners against an Exeter side that were a far cry from the one that beat Premier League Luton 1-0 in the Carabao Cup in midweek.
“It was a good day all round,” Brady said.
“It was a really strong performance from the group. I felt the movement for the first goal was excellent and the way Sam goes in one-on-one and finishes it, brilliant.
“Sam has run in from 35 yards and put it in the corner and he has beaten a very good keeper and he has finished it well.
“In the second half, we were brave to stay in the shape we were for as long as we did. And we kept catching them on the counter-attack and we had a fair few chances to be fair.
“They didn’t have a chance second half and we nullified them. We were aggressive and did the ugly side well, won our battles and played forward really well and it was a good performance.
“We reduced Exeter to one shot on target and it is really pleasing, everyone in the team was great in terms of how they worked. Exeter have got a massive squad and we haven’t, we need those players.
“Our fans were brilliant, they have travelled and we wanted to give them something back.”
Exeter boss Gary Caldwell had few complaints with the outcome.
He said: “It was a really disappointing performance. We didn’t get going at any point or didn’t deserve anything from the game. All credit to Northampton, they were better than us and deserved to win.
“I think we were sluggish and that’s a result of Tuesday night. I think it’s the realisation of playing Saturday-Tuesday but if we want to be a big team and a big player, then you have to stand up to that test.
“We did everything to recover the players on Wednesday and Thursday and prepared yesterday, as we normally do, but when the game comes, you have to be ready emotionally, physically to give everything to win a game of football and we were nowhere near the level we expect.
“Some players are getting opportunities and not taking them. Coming out and showing what you are all about on a Saturday is the true test of a footballer but, too often, people have come out and not delivered and we have to change that very quickly if we want to have a successful season.”
