Pompey Women survived a late scare to see off Moneyfields at Westleigh Park and reach the final of the Hampshire Cup.
Fierce rivals Southampton now stand in the way of the Blues lifting the silverware for the 13th successive season.
Tamsin de Bunsen and Dani Lane gave the hosts a commanding lead, only for Charley Wilson to net against her former club and ensure a nervy finale.
Jay Sadler made four changes from the side that hit 13 unanswered goals past AFC Portchester in the PDFA Cup earlier in the week.
Hannah Haughton, Rebekah Tonks, Ava Rowbotham and Evie Gane all returned to the starting line-up, with Libby Kingshott, Lena Stroem, Freya Jones and Rosie McDonnell making way.
Moneyfields proved a tougher nut to crack, but the hosts still looked to dominate right from the kick-off.
They had an early opportunity when Cherelle Khassal and Shannon Albuery exchanged passes on the edge of the box and the latter fired narrowly wide.
Khassal then rounded keeper Lauren Sayler, but her shot from an acute angle came back off the post.
And Albuery’s attempt was heading for the net midway through the first half, only to be blocked by a defender.
The visitors were looking resolute and organised at the back, while Emma Pinder could only shoot over at the other end of the pitch.
Pompey did finally break the deadlock shortly before the interval, courtesy of a fine strike from DE BUNSEN.
The ball was knocked down to her by Albuery, with the forward taking a touch before curling it into the top corner.
Half Time: Pompey 1 Moneyfields 0
The Blues had the lead, but set about looking for further goals in order to snuff out any hopes of a comeback for their opponents.
Another attempt from de Bunsen flew narrowly past the post following good work by Jaime Gotch and Khassal.
But the hosts were forced to make a change on the hour mark, with Rowbotham picking up an injury and being replaced by Freya Jones.
It was LANE who doubled the advantage just seconds later, however, with a volley from the edge of the box that was fumbled over the line by Sayler.
That seemed to be enough to secure Pompey’s place in the final, only for Wilson’s header from an Ellie Kirby delivery to reduce Moneyfields’ deficit.
But the home side saw out the closing stages to reach another Hampshire Cup final and set up an exciting derby contest.
