Guernsey got revenge for November's loss to London South Africa
A dominant second-half performance by Guernsey Rugby Club saw them beat London South Africa 37-17 at Footes Lane on Saturday.
At half-time the two sides were locked at 10-10 but three second-half tries saw Guernsey surge to another win.
Guernsey are three points clear in eighth spot in London South West Three, two points off their opponents.
"At the end of the day we were the better side," player-coach Jordan Reynolds told BBC Guernsey.
"It was a great two points but I don't think we can get ahead of ourselves really.
"I think we've got to be consistent through until the end of the season and try and build on something big. If we can get a few more wins under the belt I don't think it'll be a problem," Reynolds added.
