Wigan Athletic succumbed to another loss as goals from Dwight Gayle and Matt Ritchie, either side of Michael Jacobs’ goal, condemned Graham Barrow’s men to a third straight defeat.
The first half was a largely flat affair with neither side carving out any real opportunities.
Gayle then broke the deadlock with his 22nd goal of the season after Mohamed Diame produced a wonderful pass that only needed the slightest touch to put the hosts in front.
Barrow made a double substitution at half-time as Sam Morsy and Omar Bogle made way for Alex Gilbey and Ryan Colclough.
The additional impetus this brought for the visitors soon paid off as Jacobs latched onto Gilbey’s ball and coolly looped the ball over Karl Darlow to send the travelling fans into raptures.
The league leaders were shook and the Latics were unlucky not to take the lead when Dan Burn headed over from point blank range.
In a cruel blow to the Lancashire side, Newcastle retook the lead when Ritchie netted the winner after heading in a rebound off the post from his own half-volley.
The game petered out after this with Wigan having few chances and Newcastle seeing out the game comfortably.
Interim boss Barrow will certainly take heart from his side’s performance at St James Park, and remain seven points from safety with seven games to play.
