The tie was all but over as a contest but Sussex did not relent and stretched their advantage further through Pagham’s Jack Parkinson on 55 minutes, when he drilled home at the far post through a posse of players, despite Joe Toscani’s attempted clearance.
AFA then enjoyed their best spell of the game as Sussex took their foot off the pedal, and the visitors went close twice in quick succession - first through Mentor Ramadani, who was denied by Glover - and then Christian Gyasi-Tuffour’s goal-bound follow-up which diverted to safety off Alfie Headland.
Moments after Glover had kept him out with a wonderful reflex save, Routledge exchanged passes with Junior Mubiayi and fired beyond the advancing keeper to pull a goal back and cap an impressive individual performance.
Fittingly, though, Sussex had the final say when Pearson of Eastbourne Borough, who had stepped off the bench, added gloss to the scoreline when he fired in the final flourish having been released by hat-trick man Gould in added time.
