Sheffield Wednesday stretched their remarkable unbeaten run under manager Dave Jones to 17 matches as they dumped Fulham out of the Capital One Cup.
Although Gary Madine's 50th-minute penalty was all that separated the sides, it was no fluke win by the Owls who have started their npower Championship campaign brightly following promotion from League One last season.
Fulham, with seven Barclays Premier League goals in their opening two games this season, managed just one effort on target throughout the 90 minutes as they limped out of the competition.
James McClean reminded debutant Adam Johnson he is not the only winger on Wearside as Sunderland eased past Morecambe 2-0 and into the third round. The Republic of Ireland international claimed a double either side of the break, both goals assisted by the former Manchester City man, who shone in his first outing for his new club.
Luke Moore's double helped Swansea progress with victory over battling Barnsley at the Liberty Stadium. Goals either side of the break from Danny Graham and Moore put Swansea, who rejected Manchester City's £6.2million bid for Scott Sinclair earlier in the day, firmly in control.
But the Welsh side were wobbling after Bobby Hassell pulled a goal back for the Championship visitors, until Moore slotted his second with three minutes remaining to maintain Swansea's 100% start to the campaign.
Chris Hughton picked up his first win as Norwich manager in their match at home to Scunthorpe, but his side were pushed all the way by their lower league opponents.
Simon Lappin's first Norwich goal in almost five years and a second-half penalty from Wes Hoolahan proved just enough to see off League One outfit Scunthorpe, who had seen Mark Duffy equalise with a superb 30-yard effort.
Wigan defeated Nottingham Forest 4-1 despite being reduced to 10 men at the City Ground, while Southampton beat Stevenage by the same margin.
West Ham striker Nicky Maynard refused to celebrate after his goal helped send former club Crewe tumbling out as the hosts won 2-0, Modibo Maiga scoring the second.
