CALLUM McManaman was once again in imperious form as Latics crushed Birmingham at the DW.
The young forward scored two first-half goals as Latics cruised into a 3-0 advantage by the halfway mark.
His first goal on nine minutes was a wonderful individual effort, culminating in a low left-footed strike that went under goalkeeper Darren Randolph.
Defender Andrew Taylor doubled Wigan’s advantage six minutes before the break with a stinging strike from the left-hand channel, to register his first goal for the club.
And McManaman’s second goal, right on the stroke of half-time, was no more than Latics deserved for a thoroughly dominant opening 45 minutes.
Birmingham made a bit of a fight of it at the start of the second period, but it was too little too late.
And Wigan added a fourth goal in the final quarter when substitutes Shaun Maloney and Martyn Waghorn combined, the latter finding the net from four yards.
Birmingham were denied even a consolation at the death when Scott Carson pulled off a fabulous double save to thwart Paul Caddis and then Clayton Donaldson.
