IN THE end this result was academic - luckily for play-off bound Beaconsfield.
The Rams knew a point would secure fifth-spot but that defeat would hand Northwood a lifeline in a potentially final-day shoot-out.
But the Woods lost 5-2 at Leighton to mean Beaconsfield were booked in for an end-of-season showdown with tenants Slough Town for a place in the play-off final despite this disappointing loss.
Nathan Hicks gave Daventry a deserved first half lead when he converted the impressive Claudio Hogan’s low cross before Scott Cross doubled their advantage when he pounced on a loose ball in the box shortly after half-time.
Nervy Beaconsfield pulled a goal back 10 minutes from time through Nevin Saroya’s penalty but it was a mere consolation as Daventry held on for the win.
Byron Walton's side will now switch their attention to an intriguing Holloways Park clash with Slough on Thursday after extending their superb season.
