Dagenham manager Wayne Burnett hailed an "awesome" performance from his side as they all but secured League Two survival with a 1-0 win at Exeter.
Scott Doe scored the only goal of the game after five minutes when he crashed a near-post header into the back of the net from Matthew Saunders' well-flighted corner kick.
"We got our game plan spot on, which makes a change!" Burnett said. "It was an awesome display by our players and I can't praise them enough.
"It was a great start for us and it gave us something to hold on to. We didn't play brilliantly well, but the performance was brilliant and you need that in games when you are fighting for your life. We will take points any way we can.
"I know Exeter haven't been on a great run, but this is a difficult place to come and win. I know Paul Tisdale very well and I hope they do well because they play football the right way and they have some very good players.
"We are a young team and we got deeper and deeper and we showed some inexperience and naivety at times, but I thought we looked the more likely to score and we defended superbly."
Defeat for Exeter was their third in succession and all but ends any hopes of automatic promotion. They remain in seventh, but the chasing pack are closing in with just two points separating them and Bradford in eighth.
"It was disappointing," Tisdale said. "It has been a really bad week for us and I stood in the dressing room and listened to the players have their say.
"I'm pleased they said their piece. It wasn't heated, but it was frustrated and I am quite philosophical about it. I was very disappointed losing on Monday (against Rochdale) because at this stage of the season, you are fighting for points and we were leading with five minutes to go. We lost and that was a killer for us.
"We conceded an early goal and I would like to think we'd have got it back. It was a hard ask, but the play was disjointed. Our decision making was impaired by anxiety, frustration, panic and a bit of this and a bit of that."
