The much-changed Blues were largely comfortable throughout, but netted twice in the final nine minutes to claim a 2-0 triumph – and 97 points for the campaign.
Myles Peart-Harris opened the scoring on 81 minutes with a first-time finish from Paddy Lane’s pass, then Lane himself netted deep into stoppage time after substitute Abu Kamara struck the post.
Next stop the Championship – and here are our Pompey player ratings...
9. Callum Lang - 6
(Replaced by Christian Saydee on 65 mins) Has struggled to retain the excellent momentum he had built up before the injury, but never short of commitment and endeavour. Regardless, played a huge part since January arrival. Photo: Jason Brown
10. Paddy Lane - 8
Recalled to the side and laid on the winner with a lovely pass to Peart-Harris from the right. Had been relatively quiet until then but possesses the quality to always make things happen, as we’ve seen all season. Then capped it with a second in stoppage time after Kamara's shot hit the post.

11. Colby Bishop - 6
(Replaced by Kusini Yengi on 65 mins) Took a blow to the head in a collision with the keeper early on, but was able to continue. Had a backheeled opportunity in the first half which represented his best chance of the match. Photo: Bryn Lennon
