Sullay Kaikai’s second goal for the club, coming after eight minutes, as enough to separate the sides as Dons kept another clean sheet en route to victory.
It was a win which lifted Mark Jackson’s side to 20th in the standings, leapfrogging Stanley who slipped into the bottom four as a result.
Dons take on Morecambe, who sit 22nd, at Stadium MK next Saturday as they look to make it three wins in a row.
Here’s how we rated the players in the win over Accrington.
