Wigan's hopes of avoiding the drop were boosted as Kieffer Moore's first-half strike earned the beleaguered Championship outfit a 1-0 win over QPR at a rain-soaked DW Stadium.
Playing at home for the first time since last week's announcement that they had entered administration, the Latics went ahead in the 33rd minute when Moore rifled a shot past Joe Lumley having been played in by Sam Morsy.
Moore nearly added a second after the interval, while QPR's closest attempt was an Ilias Chair shot saved in fine style by David Marshall.
The result leaves Wigan eight points above the relegation zone with four games left to play.
But having entered administration, the club face a 12-point penalty - against which they are appealing - that will be applied this season if Paul Cook's men finish outside the bottom three.
The threat of relegation remains considerable, but Cook and his players will not be lacking in belief following this seventh win in nine games as they bounced back from Saturday's 3-0 loss at Brentford.
Meanwhile, Mark Warburton's QPR, despite a fourth loss in five, are also eight points above the drop zone.
Wigan made a lively start, with Jamal Lowe's strike bringing a stop out of Lumley in the fourth minute.
Kal Naismith had a shot deflected wide moments later and then slid to get a foot to a Moore cross but was unable to get his effort on target.
After Moore subsequently just failed to connect with a fine Kieran Dowell pass into the box, Marshall made his first save in the 23rd minute, dealing with a Bright Osayi-Samuel attempt from distance with ease.
The hosts then grabbed the lead when skipper Morsy drove forward from midfield and fed Moore, who lashed the ball past Lumley.
While QPR mustered little in response, Wigan exerted more pressure just before the break as Naismith saw a drive from 30 yards out parried by Lumley, who also grabbed a Moore header.
Moore then came close to doubling the advantage in the 51st minute as he fired narrowly wide, before Marshall made a superb stop around the hour mark to keep out Chair's strike.
The counter-attack that followed then saw Lowe carry the ball to the QPR box, where he was denied by a Lumley block.
Wigan threatened again in the 82nd minute as Danny Fox headed a corner over, then saw out a nervy last few minutes before the final whistle confirmed three points were secure.
What the managers said...
Wigan's Paul Cook: "We were flat on Saturday - we are not as flat as the people who have been made unemployed. We had to win for them tonight, for Wigan Athletic and the town, and we did that. For whatever I feel, for how much sleep I don't get, for the worst, toughest week of my football career by far, to see what goes on to other people makes my job even worse.
"People have written us off, the 12 points but we're still fighting. We're not going to get ahead of ourselves. We are not stupid, we have a real big mountain to climb. We are in administration, it's a 12-point deduction. I just hope the EFL hand
punishments out for other clubs that have been breaking the rules.
"At the minute we're accepting it, if that's going to be the case. But we've still got plenty of fight in us. None of us know the future but one thing I do know, this club must be here for a long, long time."
QPR's Mark Warburton: "They probably wanted it more than us in the first half. They've had some shocking news, appalling news and we knew they'd be united and together and angry, and they were.
"But then the second half we came out much better and controlled the first 15 minutes, and then we have to score. We can't miss from four yards out, basically into the middle of the goal, we can't miss those chances."
