Southsea Nomads snatched a narrow victory in the annual Matt Flatman Memorial match.
They edged to a 20-19 success over Tottonians III to lift the trophy for the first time in its three-year history.
It was James Clayson’s first game in charge of the Nomads and he was delighted with their efforts.
The new coach said: ‘I am proud of the way the team pulled together and the positive attitude they showed despite a few injuries.
‘The heart and determination was apparent in both attack and defence, which in the end was key to our success.’
The trophy was the second the Nomads have lifted this month – following their home success in a charity 10s tournament – as their form bodes well for the new campaign.
Club captain Ben Horrod collected the silverware from the sons of Flatman, who represented both clubs before his death three years ago.
He said: ‘It was a determined and fighting performance from all the lads.
‘Once we put into place the strategies we have been working on in training, the match started to turn in our favour.
‘It is a great feeling to win this match for the first time and bring the trophy back to Southsea with us.’
Joby Walsh opened the scoring with his maiden first-team try.
Jonathon Branston added the conversion as he delivered a faultless kicking display to take the man-of-the-match award.
The match raised more than £100 for Flatman’s family.
And his best friend, Chris Hargrave, spoke of his delight at the trophy’s arrival in Southsea.
He said: ‘The trophy is where it belongs now.
‘The club where his heart is.’
Southsea Nomads, who play in Hampshire League division two, are always looking out for new players.
They train on Wednesday evenings on the University of Portsmouth’s 3G pitches at their Langstone Campus (7pm to 9pm).
The Nomads are proud of their family-friendly environment.
This is underlined by many social events throughout the year.
