It was a game that Pompey will want to instantly consign to the scrapheap of the season.
Blackpool’s keeper was not called into any serious action until being forced to deal with a John Marquis shot in stoppage-time.
Not too much happened at the other end either, but Keshi Anderson’s drilled finish was enough to settle a dull Bloomfield Road contest.
Kenny Jackett admitted that his side were well below-par as they finally lost their unbeaten away league record and wants to see an immediate response.
The Blues boss said: “It was a game of very few chances at either end and they just started to get on top of us early in the second half.
“We couldn’t find any kind of flow and, despite making changes, didn’t really get into it, aside from two good efforts from John Marquis.
"We couldn’t create much and that’s not been like us – we’ve generally been able to get the ball to our attacking players in dangerous areas."
“For the one in stoppage-time I was wondering whether he could have squared it, but I wouldn’t pick any better player than him to be in that situation.
“We couldn’t create much and that’s not been like us – we’ve generally been able to get the ball to our attacking players in dangerous areas.
“But this was a scrappy game and they’ve been able to counter-attack with Hamilton – whose a real asset – and he’s squared for Anderson to produce the one quality moment.
“It was frustrating, especially after we went behind because we couldn’t get going and the changes didn’t necessarily change our rhythm.
“You need to be winning consistently because other sides at the top of the league will, so we have to get back to it pretty quickly.
“We have a lot of ability in our squad, but we do need to play better on Saturday and all of our focus is now on that.”
