Benson sealed the Ladies 2-Pair Division 1 title with victory over Kingston Bagpuize.
Knowing that a draw would be enough to seal the crown, Benson were on the brink after the first round which saw them lead.
It still left them needing to win one of the final round of matches - but Jan Glover and Nicola Barclay-Watt were up to the task.
They beat Peta Lloyd and Olivia Lloyd 6-2, 6-2 to give their side victory.
Ally Bremner and Sam Quinn made up the victorious Benson side.
In the 3-Pair League, there was little between the sides in the game between Woodstock and Banbury West End, which ended in a 5-4 win for the hosts.
Clare Abbott and Karen Taylor were in fine form for West End, winning all three matches at first pair.
But they were offered little support as Woodstock ran out narrow winners.
In Division 2, Witney A won two of the last three rubbers to clinch a 5-4 victory over North Oxford B.
Laura Hicks and Debbie Hempstead at No 1 pair, as well as Karen Londesborough and Carol Roughton won the crucial matches.
