Charlton put daylight between themselves and the relegation zone after running out 3-1 winners at home to Luton.
The three points put the south London side nine clear of Luton, who are rooted to the bottom of the Sky Bet Championship.
The visitors started the game stronger in attack. However, Charlton had the first real opportunity after 14 minutes when Naby Sarr turned and shot in the area – but saw his effort rattle the crossbar.
Luton still continued to press, forcing a couple of corners that ultimately came to nothing.
Lyle Taylor broke the deadlock in the 34th minute when he was able to turn and shoot past the outstretched arms of Sluga, for his 10th goal of the season.
However, the lead – and the joy of the Charlton fans – was short-lived. Two minutes after Taylor opened the scoring, Luton equalised when the home defence failed to clear the ball properly, allowing Cornick to fire home.
Charlton should have retaken the lead three minutes after the interval after Taylor delivered an excellent low cross from the left, but Green was unable to fully connect to it and put the ball wide of the post.
James Collins had the ball in the back of the net in the 51st minute but he was adjudged to be offside. Oztumer fired over the bar five minutes later after connecting to a cutback by Green.
Charlton retook the lead just after the hour-mark with Taylor netting his second from the penalty spot, after Collins handled a George Lapslie shot.
The game was effectively sealed three minutes from time.
Lapslie played a one-two with Macauley Bonne, who was able to cross the ball in low from the byline, before the former was able to tap in for his first league goal for Charlton and put the contest beyond doubt.
Luton offered little afterwards and crashed to defeat after two straight victories.
