Cole Kpekawa grabbed the only goal of the game as Pompey’s reserves triumphed over Peterborough.
The QPR loanee was named in Paul Hardyman’s team this afternoon, having been dropped from the last two first-team squads.
He responded by heading home Ben Close’s right-wing corner on 18 minutes.
Returning keeper Michael Poke twice scrambled the ball away for the Blues, while at the other end Brandon Joseph-Buadi hit the post.
Yet one goal was enough as the reserves claimed a 1-0 victory at Furze Lane.
