The Blues were 3-0 up after 26 minutes through goals from Ryan Tunnicliffe, Michael Jacobs and Ronan Curtis, with substitute Louis Thompson wrapping it up in stoppage time.
And excellent display, particularly in the second half, with so many superb displays – and here are our on-the-whistle player ratings...
13. Colby Bishop - 7
(Replaced by Joe Piggott on 76 minutes) A real mixed bag from the leading scorer. Two assists yet missed three one-on-ones to let Cheltenham off the hook. Nonetheless, there were some fine moments from him. Photo: NationalWorld

15. Dane Scarlett - 6
(Replaced Ronan Curtis on 68 minutes) So unlucky when he slipped as he attempted to tap home after keeper had parried Lane’s shot. Always injects a bit of pace and directness. Photo: National World
16. Louis Thompson - 7
(Replaced Ryan Tunnicliffe on 68 minutes) Wrapped up victory with a thumping right-footed shot from outside the box in front of the Fratton End. Photo: National World
