In-form Ipswich hammered Charlton Athletic 3-0 in front of their biggest crowd of the season at Portman Road to maintain the pressure on Bournemouth, moving back within one point of the Sky Bet Championship leaders.
Tommy Smith and Daryl Murphy continued their fine form in front of goal with a goal in each half for Town before David McGoldrick netted a deserved third in injury-time, watched by an attendance of 26,157.
Winger Callum McManaman saw red nine minutes after coming on as Wigan were beaten 1-0 by Sheffield Wednesday to leave Malky Mackay's men rooted in the bottom three at the turn of the year.
McManaman jumped at fellow substitute Claude Dielna with both feet in the 68th minute to earn his marching orders and Wednesday promptly took full advantage.
Atdhe Nuhiu nodded beyond Wigan goalkeeper Scott Carson nine minutes after McManaman's departure as the hosts suffered a third straight home loss, with Mackay having taken just one point from the 12 on offer at the DW Stadium since his appointment last month.
Derby County maintained their stranglehold over Leeds United with a comfortable 2-0 victory at the iPro Stadium that leaves the Yorkshire club just one point above the relegation zone. A crowd of 31,690 saw Derby move up to third in the table through a first-half own goal from Alex Mowatt and a Jake Buxton header early in the second.
