Jubilant boss Jim Bentley praised Morecambe's players for carrying out his game-plan to perfection as their fourth win in five games knocked Port Vale off the top of the table.
Bentley played skipper Will Haining just in front of centre-backs Chris McCready and Nick Fenton to nullify Vale's potent forwards Tom Pope and Lee Hughes. The tactic worked well and Lewis Alessandra completed a smash and grab raid with a second-half winner.
Morecambe held on despite having defender Andrew Wight sent off 18 minutes from time.
"It was a terrific win against a fantastic team with a very good manager," he said. "I hope Vale go up.
"I watched them a couple of times and knew we had to stop the supply to the front two as much as possible. We worked very hard in training on how to do that and it's come off for us.
"The game could have gone either way and fortunately the result has gone for us. We had to ride the storm, especially after we went down to 10 men, but the lads have defended magnificently, Barry Roche has made some good saves and I'm very proud of all of them."
Vale boss Micky Adams said: "We didn't play to our maximum potential and it turned into a frustrating afternoon for us. I didn't think we deserved to lose, but we didn't do enough to win either.
"We played too many aimless long balls, players were having too many touches and our set plays, which are usually very good, were average to say the least.
"The tempo of the game wasn't what we wanted, but Morecambe had a lot to do with that and their game plan has come off for them.
"We had a lack of imagination in the forward areas and we've got things to work on. We aren't the finished article and we know that. But there is no doom and gloom and we've got plenty to look forward to. What we have to do now is get back on track as soon as possible."
