John Mousinho has been nominated for the Sky Bet League One Manager of the Month award for March.
Pompey's head coach is recognised after maintaining the side's promising position at the top of the table with just a few games of the season remaining.
An unbeaten month saw the Blues secure wins over Oxford, Burton, Peterborough and Wycombe, as well as a draw at Blackpool.
Mousinho will have to see off competition from Charlton's Nathan Jones, Lincoln's Michael Skubala and Derby's Paul Warne to land the prize.
He has previously been named the division's Manager of the Month for both September and February, as well as being shortlisted in October.
The winner will be announced on Friday and is decided by a judging panel that includes former Barnsley boss Danny Wilson, Sky Sports’ EFL expert Don Goodman and Sky Bet EFL trader Ivor Davies.
