Uwe Rosler’s first home game in charge of Wigan ended in victory as Callum McManaman snatched the winner in a pulsating derby against Bolton.
The last time Latics played at the DW Stadium they were under Owen Coyle’s watch and were three goals down against Derby inside 30 minutes.
Two weeks on and with Rosler now prowling the home technical area, a Ben Watson penalty and Nick Powell’s audacious overhead kick gave them a 2-0 lead after 24 minutes.
To the visitors’ credit, they refused to fold though, Neil Danns heading home early in the second half and Andre Moritz’s penalty resorting parity.
But Rosler was not to be denied a winning start in the Sky Bet Championship as the brilliant McManaman steered in a 68th-minute winner.
Rosler had left Grant Holt behind for this week’s Europa League excursion to Slovenia in a bid to improve his fitness and it certainly had the desired effect early.
He swept an effort away from goal after good work from Powell before the Manchester United loanee had a shot blocked himself following McManaman’s purposeful probe.
It did not take too long for Latics’ up-field pressing to reap rewards.
Holt was on the end of Watson’s back-post cross and Matt Mills, losing the physical tussle with the former Norwich striker, saw the ball ricochet into his outstretched arm.
Referee Kevin Friend initially ignored the hosts’ appeals only to point to the spot on the advice of his assistant and, from the resulting penalty, Watson fired Wigan into a 14th-minute lead.
Dougie Freedman elected not to make any changes at the interval and his faith was rewarded as the Trotters pulled a goal back four minutes after the restart.
Carson did well to push Moritz’s free-kick away and with the danger not cleared, the midfielder put the ball back in where Danns was on hand to halve the deficit with his head.
The visitors surged forward looking for a leveller, Moritz stinging Carson’s palms from 30 yards and Danns then hitting the crossbar with a flicked header.
Wigan were rattled and they were pegged back to level terms when referee Friend equalled up the penalty count.
Lee Chung-yong went down clutching his face with Emmerson Boyce’s boot raised high and Friend took his time before pointing to the same spot he had in the first period.
Boyce was livid and pushed the South Korean in the face as he lay on the floor, an action which only warranted a yellow card, before Moritz blasted home the penalty.
However, just four minutes later, Latics regained the lead.
And it was, of course, Boyce who made it, flicking a corner across the box where McManaman side-footed home.
The winger appears to have been given a new lease of life under Rosler and then beat Alex Baptiste for the umpteenth time to find Powell with a cross which the forward nodded just wide.
Chances continued to come with Mason squandering a glorious opportunity by poking wide after Moritz had slalomed through.
The Brazilian could have got another equaliser in the dying throes only for Carson to repel them once more.
