The Posh attackers impressed the most with Ephron Mason-Clark’s missed penalty being the only sour note but even he made up for that.
Posh are now nine league games unbeaten.
RATINGS KEY: 10-Brilliant, 9-Outstanding, 8-Very Good 7-Good, 6-Okay, 5-Poor, 4-Awful
9. KWAME POKU
A goal and an assist in a very successful today. Did so well with the touch and finish from Mason-Clark's cross and made the third with a brilliant run. 8.5. Photo: Joe Dent
10. EPHRON MASON-CLARK
A strange game. He looked ordinary for large parts with some dodgy touches and took a poor penalty that was easy to save but he put in a great cross for Poku's opener and showed composure to round the keeper in stoppage time for the fourth. 7. Photo: Joe Dent
11. RICKY-JADE JONES
Fully justified his selection and has probably brought himself a run in the side. His pace brought the red card right after the break and he showed a calm head to finish off the third goal through the legs of the goalkeeper. 8. Photo: David Lowndes
12. ZAK STURGE (on for Burrows 65 mins)
Posh were under pressure when he came on but did little to help relieve it. 5. Photo: Joe Dent
