Portsmouth will next meet the south west champions on April 7 for the right to be promoted into Women’s Championship south west two.
Whitcher said: ‘It has been a fantastic effort.
‘This is the best way to finish our league programme.
‘London Welsh threw everything at us and our defence was superb.
‘To prevent them from scoring on their own turf is a big achievement.
‘When we made our substitutions it didn't weaken us and none of the players took a backward step.
‘It shows the strength in depth that we have in the squad.
‘Having got this far we want to go on and win promotion.’
