Pompey’s misery continued as they went down to a 2-0 loss to Walsall.
Goals from Fabien Brandy and Will Grigg at Banks’s Stadium made it 14 games without a win for the Blues.
That means another match without a maximum will equal the 15-game run without a win in Pompey’s 1999-2000 season.
The fact the visitors had their first shot on target from Scott Allan with 10 minutes left summed up their night.
It was a case of same old story in the first half.
The Blues arguably had the edge in the opening half hour and settled the better of the two sides.
But two moments of kamikaze defending made all the difference.
Both Paul Benson and David Connolly had headers over the top, while a flowing move ended with Nathaniel Mendez-Laing having a shot blocked.
But it was the home side who tool the lead in the 29th minute as Brandy got the wrong side of Mustapha Dumbuya and fired past Simon Eastwood.
It got worse for Dumbuya in the 40th minute as his attempts at playing offside came unstuck for the second.
Brandy was all on his own in the box as the full-back stepped up too late. His shot was saved by Eastwood but Grigg rolled in the follow up.
The second half proved to be a scrappy procession with Pompey rarely looking like getting back into it.
In fact, they had to rely on Eastwood to make a number of good stops in what was a shoddy half of football from both sides.
Allan mustered a shot on target in the 80th minute and there were a couple of decent efforts from Connolly - who looked fairly lively.
But the truth of the matter is Pompey never looked like making a fist of it as they remained entrenched in the League One drop zone.
