Here's how we rated the Dons players after the 3-1 triumph.
1. Laurie Walker - 7.5
Showed inevitable nerves early on, but grew in confidence. Made two excellent stops in the second half, and completes a fairytale journey.
2. Dean Lewington - 6.5
Had a quiet game as Northampton barely threatened aside from their goal in the early stages.
3. Baily Cargill - 6
Could have ended with two goals to his name, but one acrobatic effort went just wide before he missed a sitter, which he should have left for Mason. Defensively untroubled.
4. Warren O'Hora - 6.5
Making his debut, O'Hora looked uneasy initially but was unflustered in the second period as he won everything thrown his direction.
