West Newport will join Williamstown Colts (1st), Grand United (2nd) and Bellbridge (3rd) in the Williamstown and District Cricket Association A turf finals.
With one round to go in the home-and-away season, all that is left to be decided is positions in the top four.
Only two premiership points separate second to fourth.
Williamstown Colts is the only side cemented in its position and will finish as minor premiers.
