Joe Mason is edging towards challenging for a Pompey starting spot.
The on-loan attacker came through the Blues’ reserve draw with Reading on Tuesday with a 90-minute run out.
It was a display operating as the lone striker in a 4-2-3-1 system which impressed watching first-team coach Jake Wigley.
Also present at the Royals’ training ground complex for the 1-1 draw was boss Kenny Jackett.
Mason has yet to appear in League One action for the Blues following his Wolves loan switch, although featured as a substitute in the Checkatrade Trophy.
Yet Wigley was encouraged by the ex-Colorado Rapids performer.
He said: ‘Speaking to Joe, it was his first full 90 minutes for a while.
‘He played up top by himself. It was a hard role for him but he did well. He worked hard for himself and the team.
‘Joe created a couple of chances. He probably didn’t get any clear-cut chances himself but was very much involved in the attacking side of our game.
‘He is very, very good on the ball. Technically he is very good and he works the channels to open up the game a little bit.
‘His touch is excellent bringing people into play and very much the focal point of our attacking football.
‘You can train as much as you want, day in, day out but it’s nothing compared to 90 minutes of football, so it was a vital game for all our players.’
Pompey travel to Peterborough on Saturday.
