Oxford boss Chris Wilder felt his side were good value for their 1-0 victory at Dagenham.
Alfie Potter struck the only goal shortly before half-time as the U's won 1-0 at Victoria Road for the fourth season in succession.
After watching Potter's 10th goal of the campaign seal a very welcome first win in six games, Wilder said: "This is a great result for us and as you can tell I'm really delighted. We were good value. I felt we were on top for the majority of the game and we defended resolutely. This game is about creating chances and tucking them away, and in the end we've done enough.
"It can be a tricky stage of the season for teams in our position, but credit to all of the lads, they're still giving it everything and they've repaid the faith shown by our fans. I can't praise my players highly enough.
"We're not done yet, though. There's still another couple of games to go and we certainly won't be stepping off the gas at all. There's still too much at stake. I'll demand that the players continue to give in excess of 100%. They know that. If we can finish the season off on a real high that would suit me."
Hosts Dagenham are still not mathematically safe from the drop, and a run of just one win from seven games is doing little to lighten the mood.
Interim manager Wayne Burnett was not at all impressed as his side missed a couple of excellent chances, substitute Mo Shariff twice failing to find the net when well placed.
Burnett said: "There's an acute sense of disappointment among the players, and it's not difficult to see why after a defeat and a game like that. Going into the game we felt we were in a good place, but a few instructions haven't been followed and we've been punished by a quality side.
"We prepared hard and looked at lots of different ways in which we might breach them or get behind the defence, but for one reason or another the chances haven't fallen for us. I know there's only a couple of games left of the season, but we won't be using that as any kind of an excuse.
"We'll keep going at it, giving our all and we'll be striving to finish the season on a positive note. I realise some fans won't be feeling particularly positive right now, but they've been terrific for us all season and we all know we owe them a lot."
