Stephen Walker scored either side of the break as Dons deservedly sealed their spot in the last eight of the competition. Here are our player ratings...
1. Jonathan Mitchell
A late call-up following Arnold's injury in the warm-up and didn't do much wrong between the posts. Sharp stops from Fraser, Mason and Jerome but no chance for either of Walker's two goals... 6
2. Fraser Horsfall
His attempt at cutting out a through pass only succeeded in deflecting the ball to Fraser who set up Walker for the opening goal. A tough night at the back... 5
3. Cian Bolger
His late challenge on Jerome was rash and unnecessary and cost his team any chance of getting back into the game. Capped off a disappointing night... 4.5
4. Joseph Mills
Understandably rusty after three months out but did OK in a slightly unfamiliar role at centre-back. A boost to have him back ahead of a key run of fixtures... 5.5
