Full-time from The Den
Millwall extended their fine unbeaten run at The Den to seven matches as they held off a battling Wigan Athletic side to secure three crucial points.
Wigan, watched by new manager Uwe Rosler, who had been appointed as Latics boss just hours before kick-off, got off to the worst possible start when Steve Morison struck his second goal in successive games after just 92 seconds.
Striker Jermaine Easter stepped off the bench and looked to have made the win safe with a splendid second goal six minutes from the end, only for James McArthur to reduce the deficit seconds later with a curling effort beyond the reach of David Forde to set up a nervy finale.
Steve Lomas' side, showing one change from the side that faced Nottingham Forest on Tuesday with Liam Feeney in for the injured Lee Martin, got off to a perfect start with less than two minutes on the clock.
Feeney won a corner on the right when his inviting delivery was headed clear, and from Martyn Waghorn's resulting delivery, the Wigan defence half-cleared only for Jimmy Abdou to head the ball back into the mix. Morison was first to the ball, took one touch and drilled home from close range.
Having been stunned by that early goal, Wigan began to settle into their stride and they came close to equalising on the 10-minute mark. Lions keeper David Forde came to the rescue first by parrying James McClean's 20-yard effort and then making a stunning block from Emmerson Boyce to divert the ball away with the goal gaping.
Three minutes later it was Latics keeper Scott Carson called into action, comfortably saving Martyn Woolford's looping header from a Feeney cross.
On 35 minutes Woolford nearly scored what would have been a wonderful goal as he jinked his way past three Wigan defenders and hit a low drive past Carson, only to see the ball canon back off the inside of the post.
Wigan defender Stephen Crainey was shown a yellow card nine minutes after the break when he hacked down Feeney as he broke clear, with Waghorn firing the resulting free-kick into the wall.
Morison went close to adding a second goal for The Lions with a crisp shot that flashed wide, but back came Wigan and the visitors really piled on the pressure in search of an equalising goal.
Grant Holt directed a header wide of the target and keeper Forde twice made solid clearing punches from Ben Watson corners as The Lions rearguard was put under the cosh.
But it was Millwall who looked to have wrapped up the points six minutes from time when Liam Trotter, who seemed to have lost control of the ball on the halfway line, pushed on and released a stunning pass to sub Easter, and he showed great composure to slot home past the advancing Carson..
However, those celebrations were cut short when, immediately from the kick-off, Millwall switched off defensively and McArthur curled a shot beyond the reach of Forde.
In a nervous final few minutes it took the sheer brilliance of keeper Forde to deny Wigan a leveller when he somehow managed to tip Leon Barnett's goalbound header away as it arrowed towards the top corner.
Forde then punched another Watson corner clear with one last save as Lomas' side held on for a vital victory.
