Ollie Palmer scored twice as Wrexham laid to rest the ghosts of previous visits to the Chigwell Construction Stadium with a dominant win away to Dagenham & Redbridge.
Palmer scored early in each half, with Jordan Tunnicliffe also on target before the break and Jacob Mendy getting in on the act to complete the scoring.
On a frozen evening in East London, the result moves Wrexham four points clear of second-placed Notts County – now level on games – at the top of the National League table.
Phil Parkinson rang the changes for Wrexham as he looked to freshen things up after Saturday’s 2-2 draw with Maidenhead United.
With Rob Lainton recovered from illness, he returned in goal ahead of Mark Howard, while Ollie Palmer, Eoghan O’Connell and James Jones also started.
It meant Sam Dalby and Max Cleworth dropping to the bench, while captain Luke Young was rested having been ever-present in the recent relentless run of fixtures.
Ryan Barnett and Jacob Mendy both had marauding runs at the Dagenham back line without any end product inside the first five minutes.
When the goal did arrive on six minutes though, the provider was a less likely source – Eoghan O’Connell having surged forward on the overlap to deliver a right-wing cross from which Ollie Palmer volleyed in.
With Wrexham on the front foot, Elliot Lee was next to try his luck – curling a 20-yard effort just over on nine minutes after Andy Cannon drove into the area, and Paul Mullin teed the shot up.
Three minutes later, Dagenham & Redridge should have levelled – Ben Tozer was caught the wrong side of Inih Effiong, who pulled back for Jay Bird, only for him to shoot wide at the near post.
Already hampered by Junior Morias dropping out after the warm-up, the visitors were forced into an early change on 16 minutes when George Saunders replaced Dean Rance.
But the change seemed to invigorate the hosts who began to put their own stamp on the game. Angelo Balanta turned well and shot ambitiously from distance in the 19th minute but Lainton saved comfortably.
A minute later Josh Hare rose highest to meet Saunders’ cross, but planted his header straight at Lainton with the goal at his mercy.
Moments later Effiong ran at the defence and shot from distance, but it lacked power and again Lainton saved comfortably.
Wrexham nearly doubled the lead on 28 minutes, though. Jones unleashed a 20-yard shot that was too hot to handle, only for a relieved Elliot Justham to see the ball squirm from his grasp, hit the post and roll back to him.
Andy Cannon then accepted the Wrexham fans behind the goal’s invitation to shoot from distance on the half-hour, but his shot curled just wide.
Tunnicliffe did double the advantage on 39 minutes, however – stooping to head in Elliot Lee’s outswinging corner.
There was nearly a third before half-time too – Myles Weston inadvertently flicked Ben Tozer’s long throw on in the 43rd minute, and Palmer headed just over at the back post.
The half-time break could not stop Wrexham’s charge though, and within a minute of the restart Lee just failed to get a head to Barnett’s cross, and Mullin hooked well over from Mendy’s knock-down.
Palmer got the third goal in the 49th minute though, getting across the defenders to control Barnett’s low cross and finish low past Justham.
Mullin then won a 50-50 on the right-wing to work the ball inside to Jones, who shot early on his left foot, but Justham saved low.
Palmer was close to his hat-trick on 59 minutes, combining well with Mullin to work space for a low shot, but his low shot deflected wide.
Cannon then found space on his left on the hour-mark, after a patient passing move, but shot high and wide from the edge of the area.
Mendy added the fourth on 68 minutes, however, racing onto Elliot Lee’s brilliant through ball and continuing into the area before finishing low into the far corner.
Sam Dalby replaced Paul Mullin on 70 minutes, as Phil Parkinson took the opportunity to rest Wrexham’s top goalscorer.
James Jones was inches away from a deserved goal of his own in the 74th minute, turning left and then right and shooting low inside the area, only for the effort to bounce clear off the post.
Callum McFadzean then replaced Mendy on 78 minutes, and five minutes later was in on the left as Wrexham moved the ball from the opposite flank, but Justham turned his shot wide.
Sydney Ibie could have pulled a goal back for Dagenham in the final seconds, as he raced onto a through ball, but Rob Lainton was out quickly to seal a clean sheet and a big win.
