Pompey Academy talent Adam May has signed first-year professional terms with the club.
The 17-year-old midfielder made his Blues bow at the tail end of last season, replacing fellow youth-team graduate Ben Close for the last five minutes in the 1-0 home defeat to Bury in April.
And having impressed in Mikey Harris’ under-18s side all season, notching four goals in 30 appearances, May becomes the latest name off the Academy conveyor belt.
The teenager is now the fifth homegrown talent under the stewardship of youth-team boss Mark Kelly and coach Harris to turn professional.
Conor Chaplin, Brandon Haunstrup, Snorre Nilsen and Chad Field are also graduates of the class of 2015.
