Chris Dickson’s goal gave Horsham an interval lead and James Hammond doubled it shortly after half-time before Jasper Mather quickly halved the deficit.
Horsham had Danny Barkjer sent off 10 minutes from time but held on for a win which puts them up to sixth and leaves the Rocks on the bottom of the table.
