They'll face Bray Wanderers this Sunday.
Athlone Town will be playing in the League of Ireland First Division play-off final.

The final aggregate score was Athlone 1 Wexford 0.
Town manager Dario Castelo says he's satisfied to come out on top after a challenging contest:
The midlanders will face Bray Wanderers who were 2-1 winners over two legs against UCD. The First Division play-off final is set for a 5pm kick off in Dalymount Park on Saturday.
