It was a tough first half from the Blues, who found themselves uncharacteristically dominated at home as Reading dictated possession.
However, Paddy Lane’s 37th-minute opener against the run of play turned the game on its head – with Marlon Pack, Callum Lang and Colby Bishop netting after the break.
Some excellent performances from the League One leaders – and here are our player ratings...
9. Callum Lang - 8
(Replaced by Josh Martin on 85 mins) Recalled to the side and yet again proved what an excellent January acquisition he has been with effort and energy. Had a better second half with Pompey having more of the ball and produced a lovely angled right-footed finish for the third goal. Photo: Jason Brown
10. Colby Bishop - 8
(Replaced by Kusini Yengi on 84 mins) - Finally got the goal he deserved when David Button dropped Rafferty’s cross and the striker tapped into an empty net. Has Yengi breathing down his neck at the moment and that can only raise his game. Photo: Bryn Lennon
11. Abu Kamara - 9 - MOM
(Replaced by Gavin Whyte on 85 mins) No goals today but a hat-trick of assists from the blossoming winger. The first two goals came out of absolutely nowhere through his positivity and strong running, while the third he was sent away down the right by Moxon’s interception of a free-kick. Simply breathtaking . Photo: Jason Brown
