Pompey returned to winning ways to prove there is life after Steve Cotterill.
Guy Whittingham and Stuart Gray took over the reins after he yesterday walked out for Nottingham Forest.
And they managed to lead the Blues to a 2-0 victory over Barnsley.
Two goals in a minute during the second half were enough to seal the Fratton Park triumph over Keith Hill’s men.
David Norris grabbed the first on 60 minutes, flicking up Erik Husekleppp’s header before sweetly vollying home from outside the box.
Moments later Luke Varney got in on the act, pouncing from close range to ram home substitute Dave Kitson’s cross.
It was rich reward for a superb second display from Pompey during which they dominated Tykes.
However, Stephen Henderson had to be called upon to keep out Jacob Butterfield’s deflected drive.
The Barnsley skipper also struck the post with a superb 20-yard drive during the first half.
As it was, it was a welcome win for the Blues from the first of three matches in eight days.
And three points to keep the side ticking over as the search goes on for Cotterill’s replacement.
