Three second half goals from Johan Branger-Engone, Zak Dearnley and Gevaro Nepomuceno secured the three points for Oldham Athletic away at Crawley Town.
The home side had the best of the opening ten minutes as David Sesay was a constant threat down the left-hand channel.
The wingback had the first chance of the game after a driving run before seeing his shot blocked by George Edmundson.
Latics eventually started to grow into the game as Tom Hamer’s cross found Callum Lang, he laid it off to Mohamed Maouche who forced a great stop from Glenn Morris.
Johan Branger-Engone then produced a moment of brilliance down the right as he beat two Crawley men before trying to squeeze it past Morris at his near post, which the goalkeeper managed to save.
Edmundson had an effort cleared in front of goal before Luke Gambin curled an effort just over the bar as the sides went in level at half time.
Latics were let off early in the second half as hesitation at the back allowed Ollie Palmer a glorious chance, but he chipped it wide.
Branger-Engone then had one cleared off the line as Latics were pressing for the opening goal.
However, Daniel Iversen had to be at his best to tip over a Panutche Camara effort over the bar before Latics took the lead.
Substitute Dearnley drove forward and won Latics a freekick before Branger-Engone stepped up leaving Morris rooted his spot as it flew into the top corner.
Ten minutes later it was two as Branger-Engone lead the counter attack before sliding it into Dearnley who slotted home for a debut goal.
Latics weren’t finished there as another counter attack seem to break down, Nepomuceno stepped up and fired one into the top corner to seal the game.
