Pompey granted their latest Academy product a Football League debut against Carlisle on Saturday.
And Andy Awford believes more appearances are to come for Bradley Tarbuck.
The 18-year-old stepped on as an 82nd-minute substitute for Miles Storey in the 3-0 success over the Cumbrians.
The forward’s entrance arrived more than two years after making his Capital One Cup bow at Plymouth.
Yet on Saturday, Tarbuck made his maiden first-team appearance both at Fratton Park and in the Football League.
And his former Academy boss insists the Emsworth youngster’s appearance in the first team was well deserved.
Awford said: ‘I am delighted for Bradley, he deserves it after originally earning his contract as a youth-team player under me and Paul (Hardyman).
‘I wanted to try to get him on in the Johnstone’s Paint Trophy against Northampton last month but injuries wouldn’t allow us to.
‘Hopefully Saturday is the first of many for him.
‘He had his ankle injury in the summer, he had a massive set-back.
‘But that is part of the learning curve for him and I am pleased I was able to blood him on Saturday and get him out there.
‘He may get a lot more minutes in his future career.’
Meanwhile, the Academy today travel to Plymouth in the FA Youth Cup (7pm).
They drew 0-0 with Gillingham on Saturday, although predominantly fielded an under-16 line-up.
The Blues reached the third round last year, where they lost at Southampton.
