Havant completed their South League premier division one campaign with a comfortable 4-1 win away at Lewes.
There were four different goalscorers in a much-changed side for the visitors.
Mike Deller-Merricks, James Lester, Ollie Nail and Satchi Reddy were all on target in the final game of the season.
The victory means Havant finish third in the division with 48 points from 22 games.
Their opponents, meanwhile, were scrapping to avoid a potential relegation play-off match against a side from South League premier division two.
However, it was confirmed after the match that even though Lewes lost, they will not have to contest a play-off match.
Havant were not at their best in Saturday’s encounter but had enough quality in the side to see off their opponents.
Coach Ady Adams said: ‘It was a very open, scrappy game in general.
‘It was a little bit too open at times and our goalkeeper had to make a couple of good saves.
‘At half-time we talked about keeping the passing short and moving the ball around Lewes.
‘We had that bit of quality that came to the fore, which won it for us in the end.’
The opening goal was created by good work on the baseline by England youth international Laurie Bowden, who set it up for Nail to smash home.
Lester doubled the advantage with an excellent solo effort.
He cut in from the left, drove into the D and fired home an unstoppable shot.
Deller-Merricks took his goal tally to 14 for the season with a cheeky deflected effort into the bottom corner.
The final goal came courtesy of a penalty corner strike from South African Reddy.
With several first-team players unavailable for the season finale, Adams took the opportunity to give England under-16 player Tomek Bruml his debut.
‘Tomek is one of our up-and-coming stars and he came in and played right back,’ added Adams.
‘It was a good game for him to play in and get his feet under the table.’
Ady Wilkinson, who has been playing for the seconds, was also drafted into the first team.
