Their Memorial Stadium victory – which came thanks to a double from Colby Bishop – took their points tally on the road this term to 28 from their 19 games played.
Bearing in mind that the ninth-placed Blues have accumulated 57 points all season, that’s not a bad effort.
Indeed, if anything, it points to their normally reliable home form letting them down as this campaign looks set to see Pompey fall just short of a play-off place.
With that said, how would the League One table look if it were based on away points only?
Well, it would look a lot healthier for the Blues – especially thanks to Mousinho, whose four wins on the road to date equals that achieved by predecessor Danny Cowley before his sacking in January.
Here’s how the table would look.
