Grimsby fans have had plenty to cheer in recent weeks, with the team heading into Saturday's encounter on a six-match unbeaten run that saw the Mariners concede just three goals along the way. Yet that all changed on Saturday as Wrexham hit three without reply in the first 45 minutes. Striker Mullin also got his revenge after being booed by sections of the home support, with the 29-year-old effectively finishing off Grimsby with Wrexham's third of the match to end the hosts' recent good run and leave them still only six points off the bottom.
