Guernsey FC were the latest team to be beaten by high-flying Burgess Hill Town in Isthmian League Division One South as they went down 2-0 at Footes Lane.
Greg Luer gave the visitors, who have now won their last 11 successive matches, a ninth-minute lead.
Mark McGrath and Dave Rihoy went close for the Green Lions.
But Luer increased Burgess Hill's lead shortly after half-time as his shot squirmed through the hands of Guernsey goalkeeper Chris Tardif.
The loss means Tony Vance's side have won just one of their last five matches.
