Horsham YMCA moved to within two points of top spot in County League division one after leaders Eastbourne United failed to win for a third consecutive match.
Tom Manton struck the only goal with an 83rd-minute penalty as YM won 1-0 away to Lingfield.
At the same time Eastbourne United, who had lost their last two games, had to settle for a goalless draw away to Hassocks.
Those results mean YM are now two points behind United with a game in hand.
Arundel also closed the gap, moving to within three points of the leaders after a thumping 4-0 win at home to Whitehawk.
Howard Neighbour led the way with a brace while Gary Norgate and Scott Tipper were also on target.
