John Marquis put the Blues on their way with his strike in first-half stoppage-time before Ellis Harrison bagged a double after the restart and substitute Marcus Harness rounded off the scoring.
Campbell’s Shrimpers did pull it back to 2-1 with 20 minutes left through Brandon Goodship. However, Harrison bagged his second from the penalty spot and Harness wrapped up the victory. It was just a fifth league win this season for Kenny Jackett’s men, them up two places to 13th in the table. Here are a selection of pictures from Pompey’s thumping victory.
