The Lancashire side managed to continue their impressive start to the Championship season with a tight win on Friday night.
Both sides struggled to make an impact in the first half, with a lack of ruthlessness from both sides in the attacking third.
The deadlock was broken in the 53rd minute, when Josh Windass played through a wonderful ball in to the box for former Man Utd midfielder Nick Powell to nod the ball home.
The away side had a chance for an equaliser in added time, but Famara Diedhiou's header was a tame one.
The win takes the 'Latics' third in the Championship table, but there are just three points separating themselves with 9th placed Derby County.
