Lucy Quinn struck the only goal to ensure Pompey Ladies continued their winning streak with a 1-0 victory at Spurs.
The Blues have been steadily closing in on the top two in the FA Premier League southern division.
They have also embarked on strong runs in the FA Cup and the Hampshire Challenge Cup.
In all competitions the team have now won their past seven matches.
Victory at Spurs also settled a score from early December, when the north London side won 2-1 at Fratton Park.
Quinn’s ninth-minute goal proved enough as the third-placed Blues dug in for victory to cut the gap on Gillingham, in second, to two points.
Joint Pompey Ladies boss Katie Poore was pleased to get the win.
But she felt it should have been a bigger margin of victory.
Poore said: ‘It was quite a tough game.
‘We got a nice early goal and it settled a few nerves.
‘I don’t think our keeper Sadie Blakely really touched the ball in the first half.
‘We were in complete control.
‘Spurs, as expected, were a little bit more determined for the second half but they didn’t create a lot.
‘It’s not the best we have played but it was good to get the points.
‘The girls were after a bit of revenge, after losing at Fratton Park.
‘We should have won a bit more comfortably but if we can win every game 1-0, I’ll be happy.’
It was a quick counter-attacking goal that saw the Blues take the lead.
Tiff Taylor and Gemma Hillier linked up to free Nadine Bazan on the overlap.
She pulled the ball back for Quinn to slot it into the net.
Blues striker Charley Wilson thumped a shot against the post but one goal proved enough for the win.
