Hugo Rodallega struck once in each half as Wigan beat Burnley 3-1 to end the Barclays Premier League newcomers' 100% record at Turf Moor this season.
After cancelling out Steven Fletcher's fourth-minute opener after Clarets goalkeeper Brian Jensen fell to the ground in a freak incident, Rodallega added his second shortly after the restart.
That was before a rare Emmerson Boyce strike assured Wigan a first away win since the opening day of the campaign.
The opener was a simple goal, with the industrious Robbie Blake carving out space on the left before curling in a low cross to the far post for Fletcher to turn home via the underside of the crossbar.
Wigan, clearly stung into life, were back on level terms seven minutes later, and that after two superb saves from Jensen.
Initially, Jensen turned aside a rasping right-foot drive from 18 yards from Rodallega in the ninth minute.
From the ensuing corner, whipped into the far post by the Colombia striker, skipper Mario Melchiot was denied by Jensen's reactions as he blocked on the line the defender's point-blank shot.
Two minutes later, though, Jensen was an embarrassed figure as he slipped inside his own area, his foot caught in the turf, as he came to collect an innocuous Melchiot cross, giving Rodallega a simple tap-in from eight yards and ending the keeper's participation.
Substitute keeper Diego Penny was picking the ball out of his net when Rodallega scored his and Wigan's second in the 51st minute.
Collecting the ball inside the area, Jason Scotland played a simple pass back to Rodallega who unleashed an 18-yard right-foot drive into the net. Latics midfielder Paul Scharner's neat flick off Rodallega's corner teed up Boyce to sidefoot a third for the visitors.
