Pompey Women eased into the second round of the National League Cup with a 6-1 rout of Leyton Orient at Mile End Stadium.
But the Blues had to recover from conceding an early goal before eventually blowing their hosts away with a ruthless display of finishing.
Charmaine True bagged a brace, while Eilidh Currie, Becki Bath, Jade Widdows and Jade Bradley were also on target in the capital.
There were three changes from the side that beat Chichester in the league 10 days earlier, as Rebekah Tonks, Tamsin de Bunsen and skipper Amelia Southgate all returned.
Bath sent an early effort narrowly over the bar, but it was the Londoners who broke the deadlock on 13 minutes.
Otesha Charles collected a ball over the top and rounded Mel Burns before slotting into an empty net.
Their higher-ranked opponents fought back, though, and there was an instant replay, as de Bunsen slotted a pass through to CURRIE, who neatly found the bottom corner.
And they soon went ahead when TRUE battled to win possession before smashing the ball home from an acute angle.
TRUE then increased the advantage ahead of the interval, spinning to find the target after Currie’s cross had been spilled by Naomi Ogunde.
Half Time: Leyton Orient 1 Pompey 3
BATH had looked dangerous in the first half and soon added to the scoring once the action restarted, with a deflected effort from the edge of the box.
Pompey were still searching for more goals and Bath went close to another, but this time narrowly cleared the crossbar.
WIDDOWS emerged from the bench just past the hour mark and soon got on the scoresheet after twisting and turning her way into space inside the area.
The chances kept coming and Danielle Rowe was next to try her luck with a 20-yard drive that was kept out by Ogunde.
Fellow midfielder BRADLEY had more luck, however, and scored the visitors’ sixth goal with 10 minutes remaining.
Substitute Hayley Bridge saw a shot saved as Pompey continued to press, but they had already done more than enough to book their spot in the next round.
