Struggling Horsham’s search for a first win of 2013 stretched to 14 matches as title-chasing Dulwich Hamlet ran out comfortable 4-1 winners.
The South London visitors went ahead after just 22 seconds when, virtually straight from kick off Erun Oztumer headed in Nyren Clunis’s left wing cross.
The hosts then had to weather a ten minute storm which saw Hornets goalkeeper Michael Hunter twice deny Connor French.
And having withstood that pressure Horsham found their feet, Chamel Fenelon - recalled from his spell at Dorking Wanderers - had a goal ruled out for offside and Tony Nwachukwu came close with two stinging efforts from range before half-time.
But after working themselves into the game Dulwich scored their second three minutes after the restart, the impressive Oztumer reacting quickly to head his second past Hunter after the keeper had saved Clunis’ initial shot.
That goal effectively killed off any Horsham hopes and the visitors scored again on 55 minutes with a fine team move finished off by Connor French.
Simon Colbran’s Horsham continued to battle for every ball and they pulled one back when their best player Tony Nwachukwu was fouled inside the box and he beat keeper Phil Wilson at the second time of asking.
But that proved a rare moment for the home fans to cheer and after sub Francis Sawyer lashed an effort against the post Dulwich wrapped things up when sub Daniel Carr, who had a trial at Liverpool in the week, headed in a fourth.
The latest defeat leaves Horsham in real relegation danger while Dulwich looked every part genuine title contenders.
