Trailing to Joao Pedro’s 11th-minute opener, the Blues couldn’t get the ball of Hull in the first half and barely raising any goal threat as they chased and chased.
However, it was a very different Pompey after the break, levelling 19 seconds in and proceeding to cause the hosts problems with an effective pressing game.
Callum Lang struck the bar in stoppage-time and the hosts were booed off at the final whistle – here are our Pompey player ratings...
5. Connor Ogilvie - 6
Can only recall just one foray forward, arriving in the second half, otherwise focused on defending and was reasonably tight throughout. Photo: Jason Brown
6. Freddie Potts - 7
Has bounced back from the horror of Cardiff well and produced another assured performance in the centre of midfield. Everything is the minimum of fuss and he used the ball so efficiently. Photo: Jason Brown
7. Andre Dozzell - 6
(Replaced by Owen Moxon on 82 mins) Again preferred to Marlon Pack in the centre of midfield. Not much of what he does is eye-catching, but worked furiously hard and never stopped chasing and pressing. Photo: Jason Brown
8. Matt Ritchie - 8
(Replaced by Sammy Silvera on 75 mins) Handed a rare start and operated on the right-hand side of midfield. Great to see him talking to players and taking real leadership, while provided plenty of energy and know-how. Deserves more starts. Photo: Jason Brown/ProSportsImages
