Played behind closed doors at the Blues’ Hilsea training ground, the fixture consisted of two 60-minute periods, with John Mousinho’s men using 22 players.
However, it was the League One Chairboys who ran out emphatic winners through goals from Garath McCleary, Richard Kone, Beryly Lubala and an unnamed player.
Mousinho was understandably angry after the final whistle – and here are our Pompey player ratings...
17. Jamal Baptiste - 6
(Replaced Ryley Towler on 61 mins) The triallist remains at Fratton Park featuring in pre-season, although Sean Patton has departed. Strong and powerful, his presence also helps Pompey team selection, with only three contracted - and fit - central defenders on their books. Photo: Alex Shute
18. Tom McIntyre - 6
(Replaced Connor Ogilvie on 61 mins) Surprisingly introduced at left-back rather than his customary centre-half position. Definitely showed a willingness to charge down the left flank and always looks comfortable on the ball. Later reverted back to centre-half, before forced off with a tight hamstring.

19. Owen Moxon - 7
(Replaced Marlon Pack on 61 mins) One of the better performers on the day, trying to drive Pompey on. Put himself around and not frightened to challenge, but also on the receiving end of a couple of poor challenges. His corners really impressed, with Terry Devlin twice heading wide from right-wing deliveries. Photo: Jason Brown
20. Tom Lowery - 5
(Replaced Ben Stevenson on 61 mins) Was unable to spire the Blues and too often on the periphery of the game when required to affect things further forward. Still, continues to have an injury-free pre-season, which is encouraging. Photo: Jason Brown/ProSportsImages
