Pompey continued their assault on three separate fronts by reaching the semi-finals of the Checkatrade Trophy.
David Wheeler converted Gareth Evans’ corner with style in the final five minutes to see off Peterborough at Fratton Park.
That was despite the hosts making seven changes and including three teenagers in their starting line-up.
And Kenny Jackett was pleased to see the youngsters make the step up, ensuring a place at Wembley is now just one win away.
The Blues boss said: “We’ve lost two in the league, so it breaks that streak and we’ve done well in the cups this season.
“It comes during a run of five games in 15 days and so we changed the team and gave time on the pitch to some of the boys on the fringes.
"“I thought that Matt Casey, in particular, was excellent against a quality attack of Toney, Tomlin and Cooper."
“There was further experience for the younger guys – and their development is always a vital thing at any club.
“I thought that Matt Casey, in particular, was excellent against a quality attack of Toney, Tomlin and Cooper – he had good competition and should take heart from that.
“I felt that we were the better side in the first half, while Peterborough managed to get on top of us in the second.
“There was a great block by Burgess during a scramble in our box and we defended very well, especially the two centre-backs.
“Dave had some very big chances and the keeper pulled off a top save in the first half, while he just couldn’t get his foot around one after the break.
“But I’m pleased to say that perseverance won the day and he deserved a goal in front of our crowd. He finished it off well with his left foot.
“We can tuck this one away now and concentrate on the FA Cup in this very busy schedule, which is almost like the Christmas period for us.”
