Haji Mnoga and Ben Close were on target, as a youthful Pompey side beat their Luton counterparts in a friendly at Gosport.
Paul Downing and a couple of trialists also featured for Mark Kelly’s side in the 2-1 Privett Park victory.
It was the visitors who made the brighter start and they struck the crossbar twice in quick succession.
Mnoga then had a couple of half-chances at the other end, while one of Pompey’s trialists also rattled the woodwork.
And it was the Blues that broke the deadlock midway through the first half, as MNOGA raced across his marker to convert a Harry Kavanagh cross.
There were not too many other clear-cut openings before the break, although a Seok Jae Lee effort was deflected narrowly over.
But the hosts almost doubled their advantage shortly after the restart, with a Close free-kick headed just past his own post by a Luton defender.
Harrison Brook then had a long-range effort deflected wide, while Mnoga nodded a corner not far off target.
And CLOSE did strengthen Pompey’s lead on 69 minutes following some neat link-up play involving Alfie Stanley and Mnoga.
They were not quite able to hold on for a clean sheet, however, as a bobble deceived Taylor Seymour, allowing the Hatters to grab a late consolation.
Pompey: Seymour; Mnoga (Rew 87), Downing, Trailist, Kavanagh; Close, Trailist; Lee (Jewitt-White 84), Bell (Anderson 78), Brook; Stanley
