George Nikaj saw his effort go in after visiting keeper Ryan Hall failed to collect on 77 minutes and the Rocks couldn’t find the leveller in what was a spirited display at the Megger Community Stadium.
Blake handed a league debut to 16-year-old midfielder Toby Kingswell at and Preston Woolston, 18, came on as a second half substitute to make his first appearance for the Rocks after signing on trial following his departure from Havant & Waterlooville. Tommy Block saw second-half action after recovering from an injury that has seen him miss more than two months of football.
The injury-ravaged Nye Camp outfit went into the game against their third-place hosts desperate to find some form after being beaten by Sittingbourne in the FA trophy on Saturday and not enjoying much success in the league so far this season.
And they managed to deliver a gutsy 90 minutes that on another day would have given them at least a draw in Kent.
As it stands, the defeat leaves Bognor in 18th position in the league standings with a game against Canvey Island, who sit in 19th position, at Nyewood Lane on Saturday.
