Late strikes from Adam Dugdale and AJ Leitch-Smith secured victory for Crewe over AFC Wimbledon.
Nick Powell's curler put Crewe one up a minute after the break, but they were pegged back when Christian Jolley tapped in the equaliser on the hour.
Dugdale headed the visitors back in front from Ashley Westwood's cross.
The Dons again pressed for an equaliser but were caught on the counter attack, Leitch-Smith sweeping the ball in to seal victory two minutes from time.
VIEWS FROM THE DRESSING ROOM
AFC Wimbledon boss Terry Brown told BBC London 94.9:
"It was another good performance.
"I was really pleased with the way we played, but not so pleased with the way we defended.
"We gave away three dire goals and we got punished."
Crewe manager Dario Gradi told BBC Radio Stoke:
"It was a super win for the players and the supporters.
"We were under pressure in the first 20 minutes and we only took the pressure off because we started to play better.
"It was a super goal from Nick Powell, and then Duggy, bless him, came up with a great header."
