Shrivenham claimed the bragging rights in the Boxing Day derby clash against Royal Wootton Bassett at Barrington Park.
Tom Ballard gave hosts Shrivvy the lead on 33 minutes after he steered the ball home, high over the keeper after a scramble in the Bassett box.
TJ Bohane then fired wide for Bassett before Ballard had a shot tipped over the bar prior to the break.
Sam Ockwell doubled Shrivenham’s lead on 71 minutes when his powerful free-kick fizzed through the fingers of Bassett keeper Ross Milloy.
With 10 minutes remaining Bassett were handed a way back into the game from the penalty spot but Shrivenham keeper Mike Alexander anticipated Bohane’s spot kick well as he palmed the ball to safety.
The win lifts Shrivenham up to 15th place while Bassett slip down to fifth after Wantage beat Abingdon 7-1.
Elsewhere, Fairford Town brought their run of four straight defeats to an end with a superb 2-1 win at third-placed Brimscombe & Thrupp.
On target for Fairford was Jamie Reid and Dan Bailey.
