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...
1. Josef Bursik - 5
Great sixth-minute block when coming out to deny Kyle Joseph but perhaps should have come off his line to deal with the right-wing corner for Hull’s second goal. Was unfortunate to be lobbed for the winner. Photo: Graham Hunt
2. Regan Poole - 7
The pick of the defence. Scrapped and battled away as ever, producing some vital blocks and clearances. Never gives up. Photo: Graham Hunt
3. Josh Knight - 6
Looked a little flat footed for the first goal when the ball was delivered from the right. Overall, though, was strong in the air, comfortable on the ball and another solid showing. Photo: Graham Hunt
4. Ibane Bowat - 5
(Replaced by Minhyeok Yang on 83 minutes) Disappointing after such an encouraging display on Wednesday. Looked vulnerable along with Williams down the Blues’ left flank in the first half and, although he improved after the break, was the weaker of the back three. Photo: Simon Roe
