Gosport & Fareham confirmed their London one south status for another season with a convincing 39-7 win at Hove.
The Blue & Golds made no mistake on the final day when they needed at least a point to stay up.
Head coach Neil McRoberts was delighted with the way his team handled the pressure situation.
‘I’m over the moon and won’t make any attempt to disguise it,’ said McRoberts.
‘I thought the team was fantastic because the bottom line was we had to nail a result.
‘After our defeat at Charlton Park left us with the possibility of still going down, I was concerned.
‘Our backs were against the wall, particularly after we hadn’t performed in the last game.
‘This time we were great all over the pitch and superior in all facets of the game.
‘It was pleasing to see us have the desire to go on and put Hove to the sword and we could have had fifty or sixty points in the end.’
The visitors made just the start they needed with Tom Lewis knocking over an early penalty.
Lewis then scorched in for a try which Keiran McRoberts converted to give Gosport a 10-0 lead after nine minutes.
Two further Wes Dugan tries before the interval saw Gosport stretch into a commanding 22-0 lead.
In the second half Dugan completed his hat-trick of tries and Jack Brawn went over to complete the job.
Lewis kicked three conversions to finish with 14 points for the match – one point behind try-scoring hero Wes Dugan.
‘This win confirms we deserve to be competing in this league,’ said Neil McRoberts.
‘Now we can look forward to the cup final against Havant and the players are certainly up for that one.’
The second team beat Tottonians 40-7 to earn a place in the John Collins cup final to round off a good day for the club.
McRoberts added: ‘It’s great for the club as a whole.
‘Now we have to kick on in this league and make sure we keep playing as well as we did on Saturday.
‘If we can do that then we can become a force in this league.’
