Moneyfields boss Miles Rutherford joked his side are the best ‘pub team’ in Portsmouth after the Dover Road side beat rivals AFC Portchester 1-0.
Rob Evans got the only goal of the Wessex League premier division contest.
Substitute Dan Gauntlett was later sent off but the 10 men held on for a cherished victory.
They felt they had a point to prove to their high-flying visitors from Wicor Rec.
Rutherford said: ‘Carlsberg reckon we are the best pub side in Portsmouth and offered us a massive sponsorship deal.
‘Joking aside though, this is how our club was labelled some time ago by one of their management team – a pub side – and although it was far from being a sensible comment, I believe my lads wanted to show that the description doesn’t fit us.
‘It worked in our favour and our celebrations at the final whistle told its own story.
‘Okay, it wasn’t the best local derby ever seen, not many are.
‘But we held on to win the match, and deservedly so, for getting stuck in and not giving them any chance of getting back in the match.’
Youngster Evans impressed on the day – both with his defensive qualities in snuffing out the threat of Portchester’s Louie Castles and several deep crosses into the penalty area that stretched Portchester keeper Jon Webb.
It was one of those balls in that found the back of the net on 20 minutes.
Evans cut loose along the line and his far post cross dipped at the last moment and appeared to surprise Webb, who allowed the ball to slip through his outstretched hands into the roof of the net.
For the remainder of the contest, between two equally determined sides, both keepers were mostly only spectators.
Portchester’s best chance was wasted by Jamie Musselwhite after he was put in the clear by Simon Stone’s quickly taken free-kick.
Moneys substitute Gauntlett saw his 300th appearance for the Dover Road club ruined.
He was red carded for his uncharacteristic yet bad challenge on the visitors’ Joe Bye.
Portchester coach Louis Bell felt his men were unfortunate not to end up with a point.
He said: ‘We went 16 matches unbeaten since losing to Winchester City back in August and were unlucky not to have come away from Dover Road with a point.
‘Credit to Moneyfields, they did well to counteract much of what we created.
‘For me, Steve Hutchings was always a threat and young Jack Lee in their defence was excellent.’
Portchester will be looking to quickly put the loss behind them.
Bell added: ‘Graham Rix (manager) sat our lads down afterwards and told them to take it on the chin, deal with it, and begin again with a good team performance and hopefully three points when we travel to Verwood Town on Wednesday evening.’
