Full-back Andy Vance grabbed a hat-trick of tries as London two south west leaders Gosport & Fareham secured a 29-6 win at third-placed Old Reigatians.
The visitors turned on the style in the second half after struggling to make an impact in the opening 40 minutes.
‘It’s my job to make sure this team performs for the whole 80 minutes and in the first half we were poor,’ said head coach Mark Wells.
‘It wasn’t as if we hadn’t prepared properly or were not focused, because we were, but it didn’t happen for us.
‘We kicked off poorly, did some of the basic stuff wrong and fell foul of the referee at the rucks.
‘At half-time we talked about all the hard work we have put in since the summer and how we didn’t want to have that losing feeling at the end.
‘In the second half we stayed on our feet more, played off the line-out and it worked.’
Vance put Gosport 5-3 up at half-time with his first try before going on to complete his hat-trick in the second period.
Alex Heron stepped inside two defenders for an excellent try, following a good offload from centre Sam Foster, and Wes Dugan ran in for a trademark close-range try.
Alex Duncombe added two conversions.
