THE ROCKS run of five successive wins ended when they were forced to settle for a scoreless draw at Walton & Hersham.
The draw, coupled with another win for Dulwich Hamlet, means they remain top of Ryman one south but only on goal difference.
Bognor had the better of the first half but failed to take advantage of their several chances.
In the 17th minute, leading scorer Jason Prior squandered a great goalscoring opportunity from a Steve Harper cross when he hit the ball over the bar.
A few minutes later Prior again was put through by Dan Beck but the Walton keeper saved well.
On 34 minutes Harper should have scored when he was put through by Prior but he took too much time and the ball was cleared.
The home side had a good chance in the 42nd minute when lively Graeme Purdy came close with a header which hit the crossbar from a free-kick.
From the resulting corner Walton’s Michael Gordon’s tricky play meant the ball had to be scrambled clear.
At the end of the half a good move by the home side saw Moraes fire wildly over the bar.
In the 51st minute Ben Johnson’s cross was met by Prior, but his header went tantalisingly wide.
Four minutes later, a Johnson cross was met by Harper who slipped the ball to Prior but his shot was well saved by the Walton keeper.
A minute later Walton’s Purdy was put through but Stoner made a great save.
In the 65th minute, Gordon hit the ball wide over the bar after a promising home side move.
Three minutes later Harper picked up the ball on the left and cut inside but Chiweshe in the Walton goal got down to save well.
In the 70th minute Johnson cut in from the left but fired just wide.
Ten minutes later, a Bognor corner was met by Prior who hit the bar and the ball was cleared. Two minutes later, sub Terry Dodd, back from a hamstring injury, was put through but the ball was scrambled clear.
A minute later Bognor sub Callum Saunders missed an open goal following a great move as the ball sailed over the bar. In the 89th minute Dodd fired wide from a Prior cross.
In the final minute Saunders cleverly won the ball, but his lob went well over the bar with the goal at his mercy.
