WIGAN Athletic slumped to another demoralising defeat against a relegation rival to remain rooted in the Championship drop zone.
The midweek win at Reading - their first three points of 2015 - had temporarily lifted the gloom around the DW Stadium.
But any hopes it would lead to a mini revival were cruelly crushed by another setback on home soil.
Latics, without a victory at the DW Stadium for nearly six months, had started brightly, putting in an opening 15 minutes that hinted another important win was on the way.
But they fell behind to Charlton’s first attack on goal on 17 minutes, losing key midfielder William Kvist to injury in the move that led to Frederic Bulot’s opener.
Kvist’s departure was exacerbated by the loss of Leon Clarke shortly after with a suspected neck problem that saw him stretchered from the field.
And the blow of conceding a killer second goal to Igor Vetokele in first-half stoppage-time was something from which they never recovered.
Charlton created and wasted a number of chances to make the game safe before substitute Chris Eagles put Latics out of their misery in the dying stages.
Despite the best efforts of James McClean and James Perch, Latics were unable to fashion anything in the way of a response, with Harry Maguire’s header off a Perch miskick the closest they came.
