Leyton Orient 0-4 Portsmouth

Portsmouth served notice of their intent in League One with a 4-0 away win at newly-promoted Leyton Orient.

First-half goals by Marlon Pack and Colby Bishop, an own goal after the break by Orient's Omar Beckles and a penalty in added time from Kusini Yengi sunk the home side.

Pompey ran the show, handing out a harsh lesson to their hosts in the standard of third-tier football.

The visitors went in front after 23 minutes when Pack met a corner, the first of the game, and saw his effort roll gently into the net off the inside of a post.

Christian Saydee and Colby Bishop both went close before the latter doubled the lead on 44 minutes. Man of the match Gavin Whyte sent in a cross from wide on the right, Orient debutant keeper Sam Howes hesitated, allowing the unchallenged Bishop to head into the net.

Orient's plight increased on 51 minutes when Whyte sent in a teasing cross that Orient skipper Beckles turned past Howes.

Then three minutes into added time, substitute Yengi stepped forward to convert a penalty after being fouled by Beckles.
