Two goals from Billy Clarke helped Crawley beat MK Dons as the Reds won for the fifth time in six league games.
The hosts opened the scoring when Gary Alexander flicked on Nicky Adams's corner to Clarke, who fired home.
The forward extended their lead with a minute left on the clock by turning in Mark Connolly's cross.
The Dons were left to rue missed chances in the first-half from Daniel Powell and former Red Charlie MacDonald, who both hit the crossbar.
VIEWS FROM THE DRESSING ROOM
Crawley Town manager Richie Barker told BBC Sussex:
"We're gathering momentum and I thought for 65-75% of the game we were the better side but the 15 minutes we weren't the better side could have cost us.
"I said before we are never going to dominate every game for 90 minutes, so if you dominate for 65 or 70 mintues then you could argue you probably deserve to win the game.
"The one thing we talk about is the higher up you get the finishing gets better. So in League One at times people are going to miss chances and the game could have been 5-5."
