Awful defending from two set-pieces saw John Mousinho’s men enter half-time 2-0 down and they rarely looked like finding a way back.
There was even a missed penalty from Colby Bishop in the 80th minute, after substitute Florian Bianchini had won it.
Then, out of nowhere, Adrian Segecic scored a cracker from outside the box and, coupled with 10 minutes of time added-on, a rejuvenated Blues set about trying to find an equaliser.
Connor Ogilvie was booked for simulation amid appears for a penalty, which John Swift struck the bar, yet there was to be no equaliser as they lost 2-1.
And here are our Pompey player ratings...
5. Conor Shaughnessy - 6
Part of the defensive unit which conceded those awful two set-piece goals in the first half. Tested by Sargent on occasions, but largely stood firm. Photo: Nigel Keene
6. Connor Ogilvie - 7
Thought he had won Pompey a stoppage-time penalty, only to be booked for simulation. Another powerful defensive display from the Blues’ Mr Dependable. Good to see him reunited with Murphy for that important partnership, even if it didn’t quite sparkle. Photo: Steve Bailey
7. John Swift - 7
Wonderful shot from 22-yards so nearly grabbed a dramatic point. Grew into the game from playing deep and always so assured on the ball. Photo: Simon Roe
8. Andre Dozzell - 8 - MOM
Pompey have recruited three central midfielders this summer, but Dozzell is still performing strongly and worthy of his starting spot. Always in the right place and in the second half produced two superb covering interceptions. Never write him off. Photo: Steve Bailey
