Morecambe produced one of the best away performances of the season to produce the win they needed to secure their place in the Football League next season.
Jim Bentley’s side sealed their first win in 10 games to take a vital three points and halt their slide towards the relegation places in League Two in recent weeks.
The game was turned in Morecambe’s favour by two goals in two minutes towards the end of the first half.
Jack Redshaw, who was bought back into the startling line up, showed fantastic skill and composure to fire the Shrimps into the lead in the 43rd minute.
The striker took advantage of some hesitation in the Wimbledon defence to skip past keeper Seb Brown and score from an acute angle.
One minute later it was 2-0 when the Shrimps took advantage of some more hesitation in the home defence. Shaun Beeley went down in the box and as the home side hesitated again Morecambe showed a clinical side that had been missing in their game in recent weeks with Redshaw again catching the home defence out and crossing for Jamie Devitt to score from close range home the loose ball at full stretch.
The second half saw the Shrimps start well with Devitt forcing Brown into an excellent save from s well struck 25 yard effort.
Wimbledon then enjoyed a period of possession but failed to test Barry Roche as Morecambe defended superbly to keep their first clean sheet since Boxing Day.
As the Dons pushed forward they left gaps at the back and Morecambe exploited them with Brown producing a fine tip over from Kevin Ellison’s sweet strike.
But Brown could do little as Morecambe sealed a good day with a third goal in injury time. Andy Fleming was bundled over in the box and Padraig Amond slotted home the resulting penalty.
Morecame started the game on the back foot and the in-form George Francomb tried his luck with an effort that was just too high. Wimbledon’s front three were showing early signs of linking-up well, most notably when Kwesi Appiah got on the end of a lovely flick from Hylton, but his powerful drive was just over.
Wimbledon had an even better chance minutes later when Francomb sent in a great cross from the right, but Appiah headed wide.
