The final League Two Player of the Month award this season will be won by either Adam Barrett, Connor Goldson, Kemar Roofe or Jed Wallace.
Veteran centre-back Barrett started every one of Southend's seven wins in April as the Shrimpers didn't let in a single goal to move within touching distance of automatic promotion.
Another defender to enjoy a successful month was Shrewsbury Town's Goldson, who helped his side to clean-sheet victories in all four games that he played in.
West Bromwich Albion loanee Roofe netted five goals in six games for Oxford United, including a fine individual effort against Cambridge United.
Finally, Portsmouth youngster Wallace shone with three long-range strikes and was also named in the division's top 10 players.
The winner will be announced tomorrow morning.
