It looked like Pompey had squandered the chance to enjoy a Good Friday victory over Lincoln at Fratton Park.
Goals from George Hirst – from the penalty spot – and Michael Jacobs had left them cruising towards a three-point haul.
But the Imps were allowed back into the contest, with Ted Bishop and Ben House bringing them level.
Thankfully, however, Ronan Curtis emerged from the bench to slot home the winner after Sean Raggett’s effort had been parried out by Jordan Wright.
The Republic of Ireland international said: “It’s the first time I’ve seen him up there in a while and he’s claiming the assist – we’ll let him have that one!
“He did really well to get in there and I’d seen the keeper parrying a lot of things from free-kicks and corners.
“So I knew that I just needed to take the chance and get into the right position and thankfully it paid off.
"It’s the first time I’ve seen him up there in a while and he’s claiming the assist – we’ll let him have that one!"
“I just had to calm myself down and was able to keep my composure to take the ball past the keeper and slot it in.”
Curtis was pleased with the way Pompey backed up their win over Rotherham a few days earlier to secure another positive result.
He said: “We showed a lot of character in the game after not really coming out of the traps quickly enough in the first half.
“There were two good goals after the break and shooting towards the Fratton End always gives us a big lift.
“It’s not easy when you have to face two tough sides back-to-back on a Tuesday and Friday – while we’ve now got another one on Monday!
“I do think that’s been tough on the lads because we’re a small group, but we’ve done well and want to keep winning.
“It’s been nice to give the fans something to cheer about in these last couple of games because I don’t think we’ve been good enough this season.”
