Pompey Ladies booked their place in the Hampshire Cup final with a 3-0 victory at Southampton Saints.
Second half strikes from Shannon Albuery and Rachel Panting – along with an own-goal from Ellie Russell – secured a convincing victory.
There will be another derby clash in next month’s showpiece, with Southampton Women standing in the way of a 10th successive title for the Blues.
But the visitors had to be patient in their semi-final clash, as they were unable to capitalise on their dominance before the break.
Ellie Kirby had a shot saved by Hannah Haughton, while Albuery saw her effort strike the crossbar after collecting Sammy Quayle’s cut-back.
The deadlock remained unbroken until just past the hour mark, as the hosts failed to deal with a ball into their box and Albuery fired it into the roof of the net.
And the advantage was soon doubled when Albuery fed Panting, who smashed a shot into the top corner.
Pompey continued to apply plenty of pressure and when Daisy McLachlan crossed from the left, Russell inadvertently turned the ball into her own goal.
Blues boss Jay Sadler told the club’s official YouTube channel: “I’m really pleased with the outcome and keeping a clean sheet is brilliant as well.
“That’s three on the bounce for us now and it certainly gives us a platform to build upon for the next game.
"It was a deserved win overall and we’re delighted to reach the final."
“We looked solid defensively and got the ball down with purpose in the early stages, but just lacked that conviction in the final third.
“The game got more expansive as it progressed and we were able to get forward well in the second half.
“We were able to create a lot opportunities and scored some brilliant goals. It was a deserved win overall and we’re delighted to reach the final.
“There have been some decent contests with Southampton in the past, but we’re growing as a team and it will be a nice event when the tie comes around.
“Now the focus is on a trip to Cardiff in the league at the weekend, although I’m proud of the way the girls played.”
