An amazing finish in east London as the home side had a goal chalked off in the dying minyes before Wrexham grabbed the points in a melee.
Initial thoughts were for Scott Boden as the scorer, but Craig Robson seems to have been credited with an own goal.
Five changes for the visitors, as Kevin Roberts, Shaun Pearson, Paul Rutherford, Akil Wright and Alex Reid all returned - while Sam Wedgbury was out with a virus.
On just three minutes a cross from Kevin Roberts was floated into the home box and as Alex Reid looked well placed for a header from about eight yards, he saw fellow striker Chris Holroyd back track and stretch across him to head wide.
With 10 minutes gone, the Daggers did stage a series of raids and it took a clearing header from Marcus Kelly at the back post to avert the danger from Jake Howells’ deep cross.
The ball switched straight to the other end and Holroyd forced the home defence in to conceding a corner, which Kelly delivered and although Shaun Pearson got an attacking header to the ball, the referee said he had paced his effort wide, when it might well have come off his marker.
Wrexham were keeping the pressure up and once again broke form midfield with Reid feeding Holroyd on the left, but his attempted curling effort was blocked and cleared back up field.
Dagenham responded with a corner that saw skipper Scott Doe getting his header to the ball at the near post, but his effort carried over Chris Dunn’s cross bar.
On 14 minutes, Rutherford’s first cross was only headed back out to the right and Rutherford was able to send in a second cross that was strangely allowed to bounce by centre half Kevin Lokko. Holroyd reacted quickly, but was just unable to get any part of his body onto the ball and it skimmed across the face of the home goal to safety.
The home side did have the ball in the Wrexham net on 24 minutes, when Cheek’s shot was only parried by Dunn, but as Corey Whitley prodded home the rebound, he was denied by a linesman’s flag for offside.
Pearson was on hand two minutes later, to deflect Cheek’s shot high over his own crossbar for a corner. The kick came in but resulted in only a free kick to Wrexham.
Just after the half hour Mark Carrington was floored by a poor challenge by Lokko and after taking a few moments to consider the incident, he showed a red card to the Daggers midfielder.
As Wrexham looked to take advantage of the extra man, both Rutherford with a shot and then Akil Wright with a header were unable to test Mark Cousins in the home goal.
To add to their problems, the Daggers skipper Doe seemed to be carrying a groin injury, wincing whenever he touched the ball.
Although a man short, the home side were able to mount a series of attacks on the Wrexham goal, with both Dunn and Pearson doing their best to keep them at bay.
Two minutes after the restart and Holroyd was denied by a desperate back tracking keeper Cousins, who tipped over the striker’s lob from 25-yards, after the Dagenham stopper had made a poor clearance in the first place.
With an overlapping man in the box, Dunn came to the rescue saving Whitley’s shot from 10-yards, although a flag was up on the far side for an offside.
In the aftermath of that incident, Pearson was booked for a comment he made to the match official – which will trigger a one-match ban, meaning he misses the Fylde match on Tuesday.
Following a series of Wrexham corners on 54 minutes, Pearson saw his close-range header saved by Cousins.
Then on the counter attack, Kelly was booked for attempting to bring down Boucaud in the build up to a play that ended with Morgan Ferrier having a free header in front of the Wrexham goal, but only heading down into the turf!
Kelly was proving to be Wrexham’s most potent danger to the Dagenham defence and he got on the end of a cross from Rutherford’s cross forcing another save – the pair having swapped flanks.
On the counter attack, the Daggers were continuing to prove they were still very much in the game and on 63 minutes Whitely was once again ruing his luck, when he fired a low effort wide of Dunn’s left-hand post.
A few moments later, the same player fired a curling shot inches wide of the back post with Dunn watching on.
Holroyd was not far away when his effort from the left saw keeper Cousins slip as he moved across his goal, but the ball was a foot wide of the target.
A great reflex save from Cousins denied Pearson’s close range header, following one of a mounting number of Wrexham corners.
Yet again though, the home side were quickly on the attack and it took a foul by Roberts to hold them up, for which he was booked.
Wrexham’s first change saw Mackreth on for Carrington with 18 minutes remaining and Kelly switching to midfield.
A Mackreth cross after 77 minutes was aimed at Reid, but it was his marker Sam Ling who actually got his head to the ball and it looped towards his own goal before Cousins could grab it under his cross bar.
A minute later Reid did get on the end of Mackreth’s cross and forced a tremendous diving save from Cousins, going to his left to push the ball away.
Double Wrexham substitution on 81 minutes saw Massanka on for Reid, followed by Boden for Holroyd.
Still the home side belied their numerical disadvantage, with Whitely whipping in a free kick on 84 minutes that carried through for a goal kick.
Another linesman’s flag denied the home side again as Ferrier beat Roberts and passed to the near post where Bloomfield got a touch to fire passed Dunn – but not beating the assistant.
Into added time Boden’s back header was just wide as Wrexham looked to grab their own late winner.
Amazingly enough Boden (or a Craig Robson own goal) grabbed it in the 93rd minute, finishing off from close range after a melee had seen another effort cleared off the Daggers’ goal line.
