The Red Dragons were utterly dominant against John Coleman's side, racing into a four-goal first-half lead as Mullin initially got things started after just 17 minutes, nodding home Ryan Barnett's cross. It would be two shortly after, as that man Mullin grabbed his second, drilling home into the corner of the net. And the 29-year-old completed his hat-trick after just 35 minutes - this time converting Elliot Lee's pinpoint delivery to mean it was effectively game over.
Wrexham weren't done there, though, with Lee himself getting on the scoresheet with arguably the goal of the game, bending home an effort from range to put the hosts four up. The Red Dragons failed to add more to their tally in the second half, despite creating a number of presentable opportunities, but the job was already done, and Lewis Shipley's disgraceful late red card compounded the visitors' misery.
