Christian Jolley's late winner took AFC Wimbledon up to third in League Two as they beat promotion rivals Morecambe.
Jolley hit the post early on for the Dons, who then won a penalty when Gary McDonald fouled Luke Moore, but Barry Roche saved Moore's powerful effort.
Morecambe took the lead when Stewart Drummond finished following Laurence Wilson's cross from the left wing.
Jack Midson levelled by drilling home a low shot from 18 yards and Jolley won it with a header in off the post.
VIEWS FROM THE DRESSING ROOM
AFC Wimbledon Terry Brown told BBC London 94.9:
"We're starting to grow into this league and I think we deserve to be here.
"I couldn't be happier with the performance today.
"We were dominating the game for the first 20 minutes."
