Jordi Gomez fired a stunning late free-kick to finally breathe fire into Wigan's season as they cruised to a 3-0 Carling Cup win at Hartlepool.
Sam Collins' third minute own goal immediately eased the pressure on boss Roberto Martinez but Joe Gamble had a fine chance to equalise for the home side.
As Hartlepool tired, Gomez slammed his 25-yard free-kick home off the underside of the bar and substitute Victor Moses added the third four minutes from time.
Colchester keeper Mark Cousins gifted England international Darren Bent a double as Sunderland eased into the third round with a 2-0 win.
Errors from Cousins allowed Bent to strike after 20 and 37 minutes and secure the Black Cats' first victory of the season.
Ivan Klasnic began where he left off last season by firing Bolton into the next round as they beat Southampton 1-0.
The Croatian was handed his first start since rejoining Wanderers in the summer as one of nine changes made by boss Owen Coyle.
And Klasnic, who hit eight goals last term while on loan from Nantes, sank Southampton with an opportunist first-half strike.
Jon Walters helped steer Stoke through with his first goal for the club in a 2-1 win over Shrewsbury.
The former Ipswich forward, who arrived last week, made the breakthrough in the 26th minute. Eleven minutes later Tuncay added a second, both goals coming from headers, while Steve Leslie replied for the League Two side.
