Yeovil Town 0-1 Wigan Athletic
Marc-Antoine Fortune's first goal for Wigan moved the Latics to within two points of the play-off zone as Yeovil remain two points adrift at the bottom.
The French forward turned in a cross from substitute Grant Holt from close range on 78 minutes, having seen two earlier efforts cleared off the line.
Wigan winger Marc Albrighton, who is on loan from Aston Villa, also hit the bar for Owen Coyle's side.
Yeovil's Joe Edwards had a first-half shot tipped over by Lee Nicholls.
The victory was Wigan's first in the league on their travels since their opening-day thrashing of Barnsley, and the first time they have won back-to-back Championship matches all campaign.
And the Latics have now won three out of four matches following midweek Europa League action, drawing the other.
Newly-promoted Yeovil achieved their first ever home win in English football's second tier at home to Nottingham Forest a fortnight ago but, despite a bright start, were unable to secure a third win of the season.
The Glovers are the lowest scorers in the Football League with just nine goals and their early wastefulness was to prove costly.
Yeovil started well with Wigan goalkeeper Nicholls forced into a good save on 21 minutes, tipping Joe Edwards' 20-yard strike over the bar after Paddy Madden's initial free-kick had hit the wall.
A couple of minutes later, Madden blasted high and wide after being put through on goal as the hosts continued to spurn some good chances.
As the half wore on, the Latics began to take control and should have been ahead after a flurry of chances towards the break.
First Nick Powell saw a close-range shot cleared off the line, before Callum McManaman and Fortune also had shots hacked clear by the hosts in a frantic finale.
Wigan continued the pressure after the break with Fortune again having a shot hacked off the line on 65 minutes, just seconds after Ryan Shotton's header was desperately cleared away.
Striker Holt created the decisive breakthrough when a cross with his first touch was converted by Fortune.
Powell could have doubled the lead in injury-time but his heavy touch took the ball away from him.
Wigan manager Owen Coyle: "We've been outstanding in the seven games we've played this month. Anyone who's watched our games will know we have a quality side.
"I thought we had a slow start in the game, Yeovil bossed it for the first 20 minutes, but in the 10 minutes before half-time there was only one team taking charge, and that was us.
"The only reason James McClean didn't play today was because he was injured, it's as simple as that. He would certainly have been involved if he was fit."
Yeovil manager Gary Johnson: "Our cup finals are the six or seven teams down the bottom with us, starting with Doncaster next Friday.
"We play very well against the top teams, have as much possession and as many opportunities as them, but we never turn those chances into goals and wins.
"I'm not burying my head in the sand because I thought the boys worked hard today and gave everything. I love them for that."
