Newcastle old boy Charles N'Zogbia returned to haunt Sunderland as Wigan won 2-1 at the Stadium of Light.
N'Zogbia, who scored for the Magpies in a 4-1 victory at the same ground in 2006, struck with a fine solo effort in first-half injury-time to claim three points for the Latics for the first time since January 11.
It was his first goal for the club and came after midfielder Ben Watson had opened his own account early on.
Grant Leadbitter had briefly got the home side back on terms with a 41st-minute equaliser, but N'Zogbia's contribution proved decisive on a day when the Black Cats were far from their best in front of a crowd of 39,266.
The game was only 12 minutes old when the home defence backed away from a high ball as it bounced 25 yards out.
Watson, however, needed no second invitation to drill a controlled volley past Marton Fulop for his first goal since completing a #2million January move from Crystal Palace.
Chris Kirkland pulled off a fine double save from Andy Reid's deflected effort and Steed Malbranque's follow-up five minutes later as the Wearsiders responded.
But he was finally beaten four minutes before the break when, after Djibril Cisse and Kenwyne Jones had helped on Fulop's clearance, Leadbitter stabbed the ball past him.
However, just minutes later and Jones down in the Wigan box after challenging for a high ball, Paul Scharner flicked on for N'Zogbia to race from his own half before beating Fulop with a left-foot shot.
The game should have effectively been over early in the second half when N'Zogbia played Scharner in on the left only for Fulop to block with his legs. Leadbitter had a goal rightly disallowed for offside as Wigan held on for the win.
