Sammie Szmodics scored twice for Posh and whilst Sam Hoskins briefly raised hope with a penalty, Jonson Clarke-Harris converted his own spot-kick to seal the deal. Here are our player ratings from London Road...
1. Jonathan Mitchell
Beaten at his near post when Szmodics opened the scoring before being exposed by his defence as Posh scored their second and third goals. Decent stop from Taylor, but kicking was horribly erratic again and put his own team under pressure... 5
2. Michael Harriman
He was not shy in venturing forward but got little joy once in the final third. The opening goal came from his side but he was not at fault and otherwise kept things pretty tight. Excellent block prevented a fourth... 6
3. Fraser Horsfall
Troubled by balls over the top for most of the night, none more so than when Szmodics evaded his attention and raced through to score his second, though United's forward would have been offside had Mils held the line... 5.5
4. Lloyd Jones
Dragged out of position when United broke the deadlock and then tackled by his own man shortly before the home side retook the lead. Did well against Clarke-Harris, not giving the league's top scorer a sniff from open play... 5
