Latics snatch late point
Antolin Alcaraz's late header salvaged a point for Wigan in a 1-1 draw after debutant Asamoah Gyan had opened the scoring for 10-man Sunderland at the DW Stadium.
The Wearsiders had their captain Lee Cattermole - a former Latics player - sent off in the first half but took the lead in the 66th minute when substitute Gyan converted Jordan Henderson's cross.
The hosts came away with a point though thanks to Alcaraz, whose effort three minutes from time caught Black Cats goalkeeper Simon Mignolet cold.
Wigan had the better of the early stages but were let down by some wayward finishing.
Mohamed Diame shot wide while Hugo Rodallega had a shot deflect off-target by Nedum Onuoha.
The Latics' task was made considerably easier after Cattermole saw red. The visitors will argue the first booking was harsh but the midfielder gave referee Andre Marriner little option when he lunged in needlessly on Rodallega four minutes later.
Sunderland boss Steve Bruce brought on club-record signing Gyan for Danny Welbeck at half-time in an attempt to rejuvenate his troops but it was Wigan who remained on the front foot, with Rodallega firing at Mignolet and sending another effort just wide when he might have been expected to score.
Mauro Boselli then had another attempt which went high over the crossbar, but Latics fans were sensing that a goal was not far away.
That proved to be the case, but it was Sunderland who found it against the run of play as Gyan volleyed Henderson's inch-perfect cross past Ali Al Habsi.
The leveller came when on-loan Manchester United youngster Tom Cleverley volleyed a loose ball back into the area and Alcaraz stooped to head past Mignolet.
