Welling United 0-2 Braintree Town
Braintree kept alive their outside chances of a play-off place thanks to a Kenny Davis double at Welling.
Welling almost took an early lead when defender Alfie Mawson's free-kick clipped the top of the crossbar.
Home keeper Lee Butcher pulled off a fine save to keep out a Davis header but he was unable to stop a strike from the same player which made it 1-0.
James Mulley hit the post for Town before Davis converted his second from the penalty spot.
Braintree are now three points off the play-off places with three games in hand over Nuneaton.
