Watson (left) celebrates with team-mate Melchiot after his winner against Hull
Wigan moved up to seventh in the Premier League after Ben Watson's goal gave them victory over Hull.
Watson chipped in a shot late on following keeper Matt Duke's weak punch from a long Mario Melchiot throw.
The goal rewarded Wigan for their efforts after they had dominated most of the game and seen Maynor Figueroa and Hugo Rodallega hit the woodwork.
Manucho had a header saved in a rare chance for Hull, who eventually succumbed to the Wigan pressure.
The victory was little more than Wigan deserved and their desire to challenge for a potential European berth proved the greater driving force compared to Hull's attempts to stop getting sucked deeper into the relegation dogfight.
Now we must kick on - Bruce
Hull lacked intensity and urgency, while only the home side's lack of a ruthless streak in front of goal kept matters level for so long.
The visitors were nearly caught out as early as the second minute when a Figueroa cross was caught up in the wind and almost embarrassed Duke, whose blushes were saved by the crossbar.
It was the first of a number of close calls for Hull as the triumvirate of midfielder Paul Scharner and strikers Rodallega and Mido proved a constant menace.
Scharner acted as the conduit between attack and defence as he utilised his team continually catching Hull out in possession to set his front two on to the visitors defence.
