Sittingbourne made three changes from the XI that started against East Grinstead last Saturday and one of them, Dartford loanee Ikechi Eze, was to prove the match winner.
Sittingbourne keeper Jordan Perrin was the busiest of the two keepers in the first half turning a shot from Tom Tolfrey round the post on nine minutes and punching a free kick effort away on 36 minutes.
Enoch Adjei had Sittingbourne’s first serious effort when on 24 minutes he fired in a shot, the ball speeding narrowly past the far post.
Sittingbourne left their best spell in this first half to the last ten minutes, first Ikechi Eze’s free kick was headed out by a Three Bridges defender, but only as far as an unmarked Brodie who fired his shot way over the bar.
Sittingbourne were not to be denied and took the lead right on half time when Chris Barnard beat a couple of players to set up Ikechi Eze who fired past Bridges keeper Kieron Thorp.
Sittingbourne stepped up a gear in the second half and with Tom Fagg joining the fray they looked a lot more dangerous.
However, Three Bridges were still a real threat and finished strongly they hit the woodwork twice in the second half.
In the 90th minute Three Bridges had the ball in the back of the net but it was given offside.
This was not a vintage performance but Brickies will be pleased they still managed to get three points. The victory puts Sittingbourne in 10th place in the league, just three points off of a play-off place.
With all the bottom three teams losing, as happened last week, Three Bridges remain third from bottom.
