Latics produced a sensational away performance to come from behind twice and stun Sky Bet League Two leaders Newport County.
Trailing as early as the eighth minute, Harry Kewell’s side struck straight back through Davis Keillor-Dunn, only to go in at the break behind.
Yet goals from Conor McAleny and substitutes Alfie McCalmont and Zak Dearnley completed an amazing comeback in the second period as Latics equalled a club record seventh straight away win.
The fact this was also Newport’s first home league defeat of the season was full testament to a brilliant display from Kewell’s side, whose win was embellished with two magnificent goals.
Newport took the lead with a fine strike of their own, the dangerous Scott Twine unleashing an unstoppable drive from distance.
But Latics were only behind for six minutes, Keillor-Dunn sliding a shot home after Harry Clarke’s pass was flicked on by Sido Jombait.
The visitors proceeded to apply good pressure, McAleny should have made more of an angled effort inside the area after a quick break while Dylan Bahamboula also created a good chance for Bobby Grant.
It was against the run of play that the home side regained the lead five minutes before the interval, Scot Bennett making the most of the space afforded to him by the Latics defence to turn and fire a low shot past Ian Lawlor.
But more drama was about to follow in the second period, beginning with a truly wodnerful individual effort from McAley to draw Latics level again just before the hour.
As the ball bounced 30 yards from goal, the attacker struck a sweet strike past the dive of the outstretched Nick Townsend.
For the second away game running, Kewell’s side also had Lawlor to thank for a game-changing penalty save, this time keeping out Padrig Amond’s penalty on 71 minutes.
It gave Latics the impetus to stage a grandstand finish with two goals from substitutes to seal the points in style.
With five minutes to play, McCalmont steered the ball home at the far post after good work from Bahamboula.
And moments after seeing his header hit the bar, Dearnley wrapped it up with another long-range brilliant effort, receiving the ball from Keillor-Dunn before rifling it home to secure fantastic win.
