Havant remain in trouble in London one south after slipping to an 18-17 defeat against Sidcup at Hooks Lane.
Captain Joel Knight had a chance to snatch the win with the final kick of the game but for once his boot failed him and he put his conversion wide.
‘We are still in the bottom three and that is not the place we want to be,’ said Havant coach Will Knight.
‘The encoraging thing is we have now played everyone in our league and I don’t believe there is anyone we cannot beat on our day.
‘We do, however, need to start delivering results.
‘This was a game where I feel we threw away three points because we could easily have won it.
‘We paid the price for not taking our chances early on and ended up in another dogfight.
‘If we are to succeed we have to be more clinical.’
Havant led 6-0 at half-time through two Joel Knight penalties and it continued to be a tight affair after the break.
With 10 minutes remaining, Sidcup led 18-12 after crossing the Havant line for two tries. The home side spent the closing stages trying to save the game and at the death Josh Blackburn forced his way over for a try.
Joel Knight has rescued his team on at least two occasions this season with last-ditch kicks but this time it wasn’t to be.
Locks Heath Pumas moved up to third in Hampshire two with a 10-5 win over fellow promotion chasers Ventnor at Brookfield School.
The only score in a tight opening 40 minutes came from a penalty kicked by Pumas scrum-half Nick Destefano.
When the Pumas lost Matt Lawrence at the start of the second half the game went to uncontested scrums.
Pumas grabbed the initiative with the first try when skipper Tom O’Grady chased a Charlie Hayes chip.
Destefano’s conversion extended the Puma’s lead before Ventnor hit back with a try in the closing stages.
‘It was too close for comfort,’ said Pumas’ Damien Sambrook.
‘A lot of credit has to go to the players who got a late call up and played out of position.
‘We had fantastic support on the sidelines, too.’
