Wanderers will carry a 4-1 lead into Monday's play-off semi-final second leg at Adams Park after scoring a resounding victory at Fleetwood on Friday night.
Nnamdi Ofoborh crashed home an unstoppable drive inside the first two minutes to get the visitors off to an explosive start, but the hosts levelled with a softly-awarded penalty, neatly tucked away by Ched Evans.
Joe Jacobson then scored direct from a corner as keeper Alex Cairns lost the ball's flight in the wind, but the left-back's chance to net his second of the game was denied by the keeper from the penalty spot after Lewie Coyle had seen red for a dreadful challenge.
Fleetwood substitute Paddy Madden saw red to reduce his side to nine men, firstly being booked for simulation and then receiving a second yellow for dissent straight after.
There was no more drama as the Blues returned south as just one of two teams in EFL history to score four goals away from home in the first leg of the play-offs.
