Joe Garner scored the only goal as Wigan ended their first season back in the Championship with victory over Millwall.
With both sides safe from relegation, there was a predictably flat atmosphere inside the DW Stadium.
But Garner lifted the mood with what was to prove the only goal of the game when he smashed home left-footed after Nick Powell’s shot was parried by Millwall keeper David Martin.
The visitors thought they had levelled when Ryan Leonard converted from Shaun Williams’ corner only for the referee to award Wigan a free-kick for a foul.
And the Lions went close again when Jake Cooper stabbed the ball goalwards only for Powell to clear off the line.
Lee Gregory then forced a fine save from Wigan keeper Christian Walton after the break, but Millwall were unable to find a way through as the hosts held on.
Wigan, whose victories over third-placed Leeds and Preston over Easter lifted them away from danger, took off captain for the day Reece James off in the closing stages, with the on-loan Chelsea youngster given a standing ovation following a stellar season.
Paul Cook’s side, League One champions last season, finish the season in 18th place, nine points clear of the relegation zone, with Millwall 21st, four points better off than relegated third-from-bottom side Rotherham.
