Seventeen-year-old Max Clayton scored the goal which sent Crewe to Wembley for the npower League Two play-off final courtesy of a 3-2 aggregate win over Southend.
Substitute Clayton had only been on the field 10 minutes when he tucked the ball home to put his side 3-1 ahead in the 86th minute.
Ajay Leitch-Smith had earlier opened the scoring for the visitors before Neil Harris levelled for Southend in the second half. Clayton's strike appeared to be enough but Chris Barker ensured a nervy final few minutes for the visitors when he headed Southend level on 88 minutes.
