Pompey’s winning run came to a close as they fell to defeat to Bristol City.
The home side picked up a 2-1 success at Ashton Gate to bring the Blues’ six-game run of successes to a close.
That meant Steve Cotterill’s men failed to equal the club’s record run of wins, despite having the best of the play.
But there was the silver lining of Jamie Ashdown grabbing the club’s post-war league record of minutes without conceding a goal.
Ashdown made it 636 minutes without shipping a strike, before Albert Adomah opened the scoring after 40 minutes from a fine solo run.
Greg Halford’s own goal 20 minutes after the restart doubled City’s advantage before Dave Kitson pulled a consolation back in stoppage time.
Pompey had huge banks of play as they were roared on by around 1,300 rowdy away fans.
They failed to turn that into clear-cut chances, though, with Hayden Mullins’ effort after 12 minutes their best chance before Kitson’s goal.
The result means Pompey are now 13th in the table - nine points off the top six.
