Sam Hoskins fired Town ahead on 16 minutes when he converted a penalty brilliantly won by striker Kieron Bowie.
The Cobblers held on their lead until the 64th minute, when the visitors got the equaliser their slick passing football probably warranted through a close-range finish from Northern Ireland international striker Josh Magennis.
Town weren’t at their best as an attacking force, but showed great heart and discipline to restrict Wigan to minimal chances. Here are our player ratings from Sixfields...
5. Patrick Brough
Left-back Brough was kept very busy in defence so didn't get forward as much as usual. Had his hands full against the pacy Martial Godo, but stuck to his task... 6.5 Photo: Pete Norton
6. Shaun McWilliams
You know you are always going to get 100 per cent effort and commitment from McWilliams, and he didn't let anybody down on that front as he put a real shift in. At times lacked his usual composure on the ball though... 6.5 Photo: Pete Norton

8. Mitch Pinnock
One of those days when nothing quite went right for Pinnock. Worked his socks off, and was always looking to try and create, but nothing quite came off. The one time it did, he was cynically fouled by Charlie Hughes, who somehow escaped getting a yellow card... 6.5 Photo: Pete Norton
