First-half goals from Callum Hendry and Joe White saw Scott Lindsey’s side take a 2-0 lead into the break.
Chesterfield’s spirited second-half showing saw them get one back through Darren Oldaker, but it was not enough as Dons claimed their first win in four.
Here’s how we rated the players.
1. Tom McGill - 7.5
Was serenaded with a new chant from the Dons fans all afternoon, and repaid them with a fine show. Made two excellent stops in the first-half and then a brilliant denial off the line at the death | Jane Russell
2. Luke Offord - 7
Looked back to his usual self in the back line again, getting down to the nitty gritty of defending | Jane Russell
3. Nico Lawrence - 7.5
A strong and controlled performance from the centre-back, a good return to form | Jane Russell
4. Sam Sherring - 7
Another assured outing, making some really crucial challenges in the latter stages | Jane Russell
