Portsmouth chalked up a fourth consecutive London two south west win by overpowering Basingstoke 34-0 at Rugby Camp.
Greg Hoolihan grabbed a brace, while Darren Crabbe, Damian Gibbs, Jackson Clarke and Ryan Wilkie added scores of their own as the Hilsea club proved too good for their visitors.
‘Recent results have ben very pleasing,’ said Portsmouth player-coach Ben Dudley.
‘It was nice to keep a clean sheet because we have been doing a lot of work on our defence in training.
‘We had the lion’s share of possession and territory and it was a case of breaking down a spirited defensive effort from Basingstoke.’
Playing into the wind in the first half, Portsmouth established a 12-0 lead at the break through Hoolihan and Crabbe tries.
In the second half, Hoolihan showed good control at the back of a driving maul for his second and Gibbs added the bonus-point try.
Further tries from Clarke and Wilkie emphasised the home side’s superiority.
Elsewhere, United Services completed a league and cup double over Camberley with a 22-15 win in London three south west at Burnaby Road.
Services, who earlier this season knocked the table-toppers out of the RFU Cup, surprised them for a second time.
‘This is absolutely our best performance yet this season,’ said director of rugby Matt Davis.
‘We remained structured and composed throughout and our discipline was immense.
‘All game we only conceded four penalties and that was in the most difficult of conditions.’
Camberley took an early lead with a converted try but Services responded with a Scott Carter score and a Jimmy Taylor penalty.
In the second half, hooker Dave Reed peeled around the front of a line-out for a try – also converted by Taylor.
Camberley roared back to level at 15-15 with a converted try and a penalty but Services had the last say.
With 10 minutes remaining the home side were awarded a penalty try when Camberley collapsed a driving maul close to the line.
In Hampshire two, Southsea Nomads lost 27-14 at Overton.
Sam Price and Jonathon Branston scored the Nomads tries with Branston converting both.
In a tight affair the dominant Overton scrummage proved the key to their win.
