Pompey’s battling 2-0 victory at Tranmere saw them set a new club record.
It was a ninth successive win – a feat not achieved since they first entered the Football League 100 years ago.
Goals from Sean Raggett and Ryan Williams got the job done at a blustery Prenton Park, earning a move up to fifth spot in the standings.
And Kenny Jackett was thrilled with how his side fared against their spirited – albeit struggling – opponents.
The Blues boss said: “The record’s fantastic and we’re delighted – the players should be very proud and it means we’ve got a lot to play for in three competitions.
“We need to recover well, avoid injuries, keep our rhythm and rise to the challenge in the last third of the season.
“It was always going to be a tough game at Tranmere, so I was really happy with the outcome and we had to be at our best defensively.
"The record’s fantastic and we’re delighted – the players should be very proud."
“Cook and Vaughan were a real handful up front and they made it difficult to get out, along with the slight slope and a bit of wind.
“But then we took advantage of that from the start of the second half and got a very good goal from Ryan Williams.
“It’s something we’ve been talking about because he gives us so much and we want him to add goals to his game.
“I’m also pleased for Sean because he’s stuck at it and shown good character – as a number of players have during the course of the season.
“He’s benefitted from a strong partnership with Christian Burgess and the pair of them have grown as the games have gone on.
“The goals were the most pleasing aspect and we had good chances to score even more, which is encouraging.”
Pompey were without the in-form Andy Cannon at Rovers, but the midfielder should not be missing for long.
Jackett said: “He’s been feeling his glute and actually came off the pitch holding it the previous weekend.
“He’s had a scan and it doesn’t seem too bad, but he’s been in a bit of discomfort during the week and did a minimal amount of training.
“We decided that he wasn’t fit to play and we’re hoping that by Tuesday or next Saturday, he’ll be okay.”
