Andy Barcham capped his return to action with a goal as Pompey inflicted a 4-1 defeat on Leyton Orient.
But Paul Hardyman was left scratching his head how his side didn’t win even more emphatically during a dominant reserve-team display.
With the Academy in action last night, the Blues fielded a strong side for yesterday afternoon’s trip to Brisbane Road.
Jack Whatmough and Joe Devera were given first starts following injury, while top-scorer Jed Wallace also featured.
There were also second-half appearances for Barcham and Danny East after recent lay-offs.
Yet the vistors were level at 1-1 at the break.
Nigel Atangana’s opener was cancelled out by Ayomide Adeboyojo against the run of play.
After the break, substitutes Barcham, East and Johnny Ertl all scored as Pompey cantered to a dominant victory.
First-team coach Hardyman, though, felt the scoreline should have been far greater.
He said: ‘It was quite pleasing in lots of ways, particularly in the fact we created 30-odd goal-scoring opportunities.
‘Playing against a younger team and with us being an experienced team you would expect that.
‘The disappointing thing was we didn’t finish those chances off.
‘But when you are creating those chances it is good.
‘It was a good attitude from the lads and we asked for a bit more professionalism in the second half and got that.
‘We capitalised with the three goals to finish the game off comfortably.
‘We should have had another couple of goals on top of that, if not more.
‘The keeper did make some good saves but we created some good chances.
‘I added up 17 shots in the first half and of that 17, nine shots were on target which shows how much we dominated the game.’
Hardyman was delighted to see East and Barcham get some match action.
He was also pleased to see Ertl make an impact after coming on.
‘It was really pleasing Danny East came on after a long-term injury and Andy Barcham, with both scoring,’ said Hardyman.
‘Johnny Ertl also came off the bench to score, so perhaps the substitutes might have felt they had a point to prove!’
Meanwhile, Pompey’s clash with Tranmere at Fratton Park on Saturday, January 3 has been postponed after Rovers reached the third round of the FA Cup.
The new date has yet to be announced.
