Portsmouth’s difficult start in London two south west continued with a 63-15 defeat at Cobham.
It was the Rugby Camp outfit’s third successive loss of the campaign.
Player-coach Ben Dudley accepted his team came up against opponents who were just too good.
‘It was a tough day at the office and we were always up against it,’ said Dudley.
‘We did well for the first half-hour but couldn’t keep them under any sustained pressure.
‘Every time we made a mistake they were ruthless and punished us.
‘We trailed 30-8 at the beak and that left us chasing the game.’
Portsmouth right-winger Mark Ovens marked his first start of the season with two tries.
Josh Palmer knocked over a penalty – with Simon Morgan adding a conversion.
United Services suffered their first defeat of the season as they went down 13-6 at Battersea Ironsides in London three south west.
‘Our players gave it their all and the game could have gone either way,’ said director of rugby Matt Davis.
‘We got stuck in traffic and didn’t arrive until 15 minutes before kick-off.
‘That isn’t why we lost but it didn’t help.
‘In the first 15 minutes we were ill-disciplined and gave away too many penalties.
‘The game turned into a physical battle of attrition in midfield and the stop-start nature didn’t suit our style.
‘We have to be happy, though, after coming away with a losing bonus point.’
Scrum-half Ben Smith scored the Services points with two penalties.
Southsea Nomads powered to a 29-13 win at bottom club Aldershot & Fleet in Hampshire two.
‘We went into the match with a clear game plan,’ said Nomads coach Jamie Clayson.
‘The players followed it to the letter and got their rewards.
‘Despite missing a number of first-choice players we still managed to dominate.’
Alex Kasote grabbed a brace of tries with Toby Cutler and England Def international Aaron Beesley also crossing the line.
Jon Branston added two conversions.
