|Venue: DW Stadium
MILLWALL recorded back-to-back away wins for the first time this season to give their survival hopes another major boost.
Carlos Edwards' deflected first-half strike proved to be the winner on a nervy night at the DW Stadium.
Wigan poured forward in the second half in search of an equaliser but substitute Steve Morison went close to scoring a second when his effort was cleared off the line.
For the first time in his Millwall reign, Ian Holloway was able to name the same starting line up for successive matches.
The Lions boss kept faith with the side that beat Nottingham Forest 2-1, but Wigan made eight changes ahead of their FA Cup semi-final with Arsenal this weekend.
Lee Martin, whose fine strike helped Millwall secure that win at the City Ground, won and took a free kick in a dangerous area but curled over.
Ed Upson's low cross was nearly turned in by Mark Beevers in the tenth minute before Leon Barnett made a vital defensive header to prevent Stefan Maierhofer from reaching Scott Malone's centre.
Martyn Woolford then headed Martin's cross into the arms of Scott Carson as the Lions continued to create the better chances.
And their bright start was finally rewarded in the 22nd minute when Edwards burst forward unchallenged and his low drive deflected over Carson and into the net.
Martin nearly produced a carbon copy of his weekend goal to double the visitors' lead, but his effort drifted wide after he cut in from the left flank.
Former Millwall loanee Martyn Waghorn headed wide for the hosts before a mix up between Edwards and Alan Dunne let in Nicky Maynard, but the striker fluffed his lines.
In the 41st minute, Upson's defence-splitting pass found the overlapping run of Malone, whose dangerous cross into the box was cleared under the noses of a trio of Lions attackers.
David Forde made his first meaningful save of the evening on the stroke of half time to punch clear a corner and then repel Jack Collison's follow-up strike.
Goalscorer Edwards was forced off with injury at half time and replaced by Ryan Fredericks.
The hosts also made a change at the break, with manager Uwe Rosler introducing James McArhur and Marc-Antoine Fortune from the bench.
It was Fortune who had the first effort on goal of the second period, nodding a looping Collison cross wide of Forde's post.
The Latics brought on Manchester United loanee Nick Powell soon after and he spurned two chances in quick succession to draw his side level.
Wigan's best opportunity fell to the feet of Collison in the 75th minute but he curled wide with the goal gaping and Forde rooted to the spot.
And Millwall nearly added a second goal on the break when Malone's drive was parried by Carson and sub Morison twice had efforts cleared off the line.
The 327 Lions fans behind the goal felt that Morison's second attempt had crept into the goal before being cleared by a defender.
Forde held onto a late Emmerson Boyce effort as Millwall dug deep to seal successive wins away from home.
