THE Dragons took a leaf out of Jamie Hayter's book at the Racecourse on Saturday to sink the Mariners with a quick-fire treble.
Three goals inside just under three first-half minutes set up a comfortable win, going some way to banishing the painful memories of Bournemouth striker Hayter's record-breaking hat-trick against Wrexham at Dean Court last month.
Thankfully, the boot was on the other foot at the weekend as the Dragons kept up their play-off challenge and ensured incoming Grimsby boss Nicky Law's first game in charge ended in defeat.
Law joked in his post-match Press conference that you could have driven a London bus through the heart of his team's defence on occasions. And, as the Racecourse's second lowest crowd of the season will testify, he wasn't exaggerating.
This was by no means a classic Wrexham display. But strikers Chris Llewellyn and Chris Armstrong still proved far too canny for the Mariners' inexperienced back-line, while in midfield the creativity of Darren Ferguson - back after suspension - and the industry of Matt Crowell and Jim Whitley ensured the home side were never in danger of stretching their run without a win from three games to four.
The hosts took 10 minutes to get into their stride, with Armstrong's header playing through Llewellyn, whose shot was saved at close quarters by keeper Andrew Pettinger.
Armstrong was then foiled by Pettinger 12 minutes later but Wrexham finally found the breakthrough they had been probing for in the 33rd minute.
Crowell rolled the ball into the feet of Whitley on the edge of the box and the former Man City man cushioned a gentle pass back into the on-rushing Crow-ell's path. The Swansea-born midfielder then let fly with his left boot, curing the ball into the top corner from 25 yards.
It was the Wales Under-21 inter-national's first goal in professional football and it provided the catalyst for the Dragons' most potent spell of the game.
There were 35.09 minutes on the clock when Armstrong finished confidently from the edge of the box for 2-0 after being played in behind a static Grimsby defence by Ferguson.
And just 46 second later, the former Spurs hitman doubled his tally.
Ferguson picked out Llewellyn on the right wing and he squared the ball for Armstrong, whose first-time shot spun in off Pettinger's far post.
At 3-0, the match as a contest was over. Grimsby knew it and Wrexham knew it too, meaning the rest of the game was played out at a moderate pace that did little to set the pulses of the fans racing.
All the visitors had to show for their second-half efforts was a Stuart Campbell drive that bounced back off Wrexham keeper Andy Dibble's crossbar.
The Dragons' best chances of scoring a fourth goal, meanwhile, appeared to be via the help of a rather generous assistant referee, who allowed Armstrong the benefit of the doubt on more than one off-side decision.
However, despite the official's best efforts to reward the striker with his hat-trick, Armstrong was unable to add to his tally.
Craig Morgan almost bagged a fourth for Wrexham late on, but his header from a Ferguson corner deflected wide and the home side had to settle for the three goals they bagged during their first-half blitz.
Wrexham: Dibble, Whitley, Lawrence, C Edwards, Armstrong, Ferguson, Llewellyn (Sam 70), P Edwards, Morgan, Crowell (Barrett 83), Pejic.
