A disappointing display saw Lewes fall to their fifth defeat of the season, as two first-half goals from Jason Prior helped Bognor to a comfortable win in this Sussex derby at the Pan.
Steve Brown made four changes to the side that had lost 5-1 at Farnborough in their previous game, with Chris Breach, Jordan Badger, Ronnie Conlon and Alex Laing being replaced in the starting line-up by Steve Sutherland, Fraser Logan, George Brown and Elliott Levy.
The unavailability of Breach and Badger saw a defensive reshuffle for the Rooks, with Jay Lovett playing alongside Sutherland in the centre and Leon Redwood filling in at left-back. Bognor took the lead after just 11 minutes, as Alex Parsons dispossessed Lovett on the edge of the area and squared for Prior to finish past Will Godmon.
The Rooks suffered a further blow just five minutes later, as Redwood was forced off with an injury and was replaced by Alex Summerfield. Bognor were enjoying the majority of the possession, and looked capable of causing the Lewes back four problems with their pace every time they went forward.
The visitors also boast arguably one of the best strikers in the Ryman Premier in Prior, who sent a header from a Harvey Whyte cross straight at Godmon as Bognor looked to find a second goal. The doubled their lead after 22 minutes, Prior beating Richie Welch to another dangerous cross from Parsons to send a powerful header back across Godmon and into the far corner.
Lewes enjoyed their best spell of the game just after half-time, as they kept the ball better and saw substitute Troy Williams hit the outside of the post from a tight angle after a Logan cross had caught out Grant Smith in the Bognor goal. The visitors were soon back on top though, as Prior sent a powerful far-post header from a Parsons cross against the crossbar.
The Rooks continued to work hard to try and find a way back into the game, with Levy seeing a goal-bound effort blocked in the six-yard box by Whyte after a corner had not been cleared.
Bognor always looked capable of adding to their lead and were unfortunate not to do so, as Alfie Rutherford capitalised on hesitant defending by Sutherland but saw his effort from the edge of the area hit the bar and bounce clear.
Lewes were unable to build a spell of pressure to try and find an unlikely route back into the game during the closing stages, with the visitors looking the more likely scorers, as both Ollie Pearce and Stuart Green went close in stoppage time.
The Rooks will look to put this result behind them when they travel to VCD Athletic on Saturday for a crucial game, kick-off at 3pm.
