A RUTHLESSLY efficient display from Latics saw Uwe Rosler’s men cut down Forest and move into the play-off positions.
Latics took advantage of Reading being held at home to Yeovil to leapfrog the Royals into sixth spot, three points behind fifth-placed Forest with a game in hand.
Apart from a 10-minute window at the start of the second period, they thoroughly dominated at the City Ground.
The visitors - roared on by an away following of over 1,000 - took the lead just after the half-hour mark.
Jordi Gomez’s shot was diverted into the path of Martyn Waghorn, who side-footed into an empty net.
Forest equalised shortly after the restart when Jamie Paterson blasted past Ali Al Habsi with the aid of a deflection.
But Latics nipped the Forest comeback in the bud by regaining the lead midway through the second half, when Waghorn’s shot was helped home by the head of Emmerson Boyce.
It was game over four minutes later when James McArthur fired home from 25 yards.
And the icing was applied to the cake in the dying seconds when Gomez rifled home an absolute thronker from 30 yards that Karl Darlow couldn’t get near.
Forest were booed off at full-time, as they had been at the interval, which was music to the ears of everyone with Wigan connections.
