After goals from Rhys Healey, Conor McGrandles and Alex Gilbey guided them to victory at Stadium MK - here's how the players rated.
1. Lee Nicholls - 8
After some nervous early moments, puffed his chest out and stopped Portsmouth on a number of occasions.
2. Dean Lewington - 7
Solid as ever, and played a big part in Dons' second goal with a cracking pass to Healey.
3. Callum Brittain - 7
Less involved than normal at Stadium MK, but continues to mature under Martin.
