Goals from Mo Eisa and Matt O'Riley ensured their second victory of the season, lifting them to 11th in League One.
Here's how we rated the players.
1. Andrew Fisher - 6
Didn't have a shot to deal with all afternoon as Accrington only rarely threatened his goal. Their two best chances were fired wide, leaving Fisher a relative spectator. Good command of his area.
2. Dean Lewington - 6
Part of a nervous Dons backline early on but held firm when put under and pressure by Accrington. Talked himself into the book, but played a key role in Dons' opener.
3. Harry Darling - 6
Like Lewington, started nervously but established himself in the game as it wore on.
4. Warren O'Hora - 5.5
Made a lot of silly little mistakes which detracted from his game.
