James McClean helped Wigan move within six points of Sky Bet League One leaders Rotherham after a 2-0 win at home to struggling Crewe on Tuesday night.
After a goalless first half at the DW Stadium, it was summer arrival McClean who helped make the opener when his cross was headed in by Callum Lang in the 57th minute.
Republic of Ireland international McClean, 32, then wrapped up the points late on with a deflected second to ensure the Latics stay on the heels of the Millers with two games in hand while third-place MK Dons are now five points adrift.
