Brothers Wes and Wayne Dugan crossed for five tries between them as Gosport & Fareham crushed Teddington 52-10 at Gosport Park.
Centre Wayne led the way with a hat-trick, while scrum-half Wes also shone with a double.
Gosport have now secured a place in the London two south west play-offs as they go for promotion.
They are likely to meet Maidstone at Gosport Park in the battle to go up to London one south.
Gosport director of rugby Mark Wells felt some great individual displays were key.
He said: ‘It wasn’t the best of performances team wise.
‘But there were lots of outstanding individual contributions.
‘In the first half, we weren’t as structured and organised as we should be.
‘We scored some great individual tries and though the result was never in doubt we only led 17-10 at half-time.
‘When we did start to play more as a team, Teddington just fell apart.’
The home side lost hooker Tommy Russell, with an injury early on.
Jordan Humphrey moved into the centre from the wing and scored a good second-half try.
Prop forward Tom Blackburn celebrtaed his debut with a try and experienced forward Chris Thompson also crossed.
Alex Duncombe kicked beautifully to add six conversions.
In Hampshire two, Locks Heath Pumas closed the gap on second-placed Fareham Heathens with a 15-6 win over Southsea Nomads.
Pumas fell behind to an early penalty.
Nick Di Stefano levelled with a penalty before Pete Moore added a try on the stroke of half-time.
A Matt Newton try, converted by Stefano, in the second half proved enough to see Pumas home.
‘It was a scrappy affair and for the fourth-consecutive game we won without playing to our true potential,’ said coach Jim Pearce.
‘The breakdown was a bit of a mess for both teams all game and, once again, we had to work hard for it.
‘With Heathens slipping up there is all still to play for.’
Heathens saw their hopes of securing second place dented by a 35-25 defeat at Chineham.
