Manager Lee Johnson was happy to see his side book a place in the next round of the FA Cup but felt it was not their strongest performance of the season.
Mike Jones grabbed the only goal of the game in the first half, superbly curling a free kick into the bottom corner, and securing Latics' passage through to round two.
Johnson said: "We were made to work hard for it by good opposition and a good side. They have spent big and the 11 they had out was a strong team. It was a tough game for us and I'm just happy to be through and into the hat.
"That was a strong mental performance to say we lost last week to Bristol City. Some had to dig in today because we had a few that weren't feeling well. Jabo missed the game through illness and I'm delight to come out with a win although it wasn't a vintage display."
Latics lost to their League One rivals earlier in the season 3-1 but they have avenged that defeat, something which pleased the manager.
"I thought Kelly was excellent for the whole game. I thought Mills was good in the second half and I thought Jones had a dodgy 25 minutes but was excellent after that," commented the 33-year-old.
"It was a lot of ups and downs but maybe last season we would have probably lost that game so I've got to praise the character of my side."
The draw for the next round of the competition takes place on Monday, November 10 and Johnson stated his preference for round two.
"We would like the lowest rank team at home realistically. I want it at home and on our surface where we can play our game," admitted Johnson.
"There are no easy games, whether it be the lowest team or the best team. That showed today because both teams took it seriously and there is a massive prize, whether it be round three, round four or however far you go."
