LONDON - FA Cup holders Wigan slumped to a 2-0 defeat at Leeds on Wednesday in their first match since the departure of boss Owen Coyle.
Coyle parted company with Wigan by mutual consent on Sunday after just six months in charge at the Championship club, who have failed to live up to their billing as one of the favourites for promotion to the Premier League.
Coyle's exit couldn't bring an immediate reversal of fortunes for Wigan, who have lost four in a row and won only two of their last seven second tier matches.
Graham Barlow took charge of Wigan on a caretaker basis while owner Dave Whelan searches for a permanent appointment.
But the Latics, who stunned Manchester City to win the FA Cup before being relegated from the top-flight in May, looked rudderless at Elland Road.
Leeds striker Ross McCormack bundled home his seventh goal in five matches in the 15th minute and then saw his 77th-minute free-kick curl inside the far post for a game-clinching second to lift Brian McDermott's side up to seventh place in the table.
Elsewhere, Connor Sammon's late goal shattered 10-man Middlesbrough as fourth placed Derby stretched their winning run to four matches with a 2-1 victory at Pride Park.
Derby boss Steve McClaren won the League Cup and reached a UEFA Cup final during his tenure in charge at Middlesbrough boss, in his first managerial game against his old club, he saw his new team emerge somewhat lucky winners as the Teessiders' brave resistance was finally broken.
Chris Martin had given Derby a 33rd-minute lead with his 10th goal of the season after Middlesbrough's Curtis Main was dismissed.
Dean Whitehead equalised for the visitors in the 74th minute, but Sammon's 90th minute goal clinched the points for the Rams.
