Peterborough placed one foot forward towards securing their spot in Sky Bet League One next season with a convincing 3-0 win over Charlton, which significantly impacted their opponents' chances of securing automatic promotion.
The Posh now find themselves nine points clear of the relegation zone following goals from Sam Hughes, Abraham Odoh, and Malik Mothersille. Meanwhile, Charlton sit eight points adrift of second-placed Wrexham after a disappointing display at the Weston Homes Stadium.
Charlton came close to scoring in the third minute as Lloyd Jones' header from Luke Berry's corner struck the crossbar.
Peterborough broke the deadlock in the 38th minute when captain Hughes headed in Kwame Poku's cross for his first goal for the club, following a scrambled indirect free-kick by Mothersille.
Just five minutes later, The Posh extended their lead as Odoh capitalized on a pass from Ricky-Jade Jones to curl in a superb effort after cutting inside.
Despite missing several opportunities, including a clear chance for Odoh, the hosts sealed their victory with a well-deserved third goal in the 79th minute. Cian Hayes' cross into the box was calmly converted by Mothersille.
