Pagham remain third in division one of the county league after a 1-1 draw at home to Rye.
But it was a day to forget for the other two local sides in the top flight.
Chichester crashed 4-0 at Three Bridges while Selsey went down 6-1 at home to East Grinstead.
City have slipped to 12th in the table, Selsey 14th.
In division two, Midhurst lost 2-1 at Storrington, while in division three there were 1-1 draws for Barnham and Sidlesham - who were playing one another - and Bosham, who were held at Walton Lane by Forest.
