Oxfordshire Over 40s completed a clean sweep of six matches to win the Masters Challenge Division 1B title in Bournemouth.
The Oxon team of skipper Paul Casey, Dave Buckingham, Martin Graham, Simon Gaines, Nicola Patrick,Jackie Yeulet, Laura Hicks and Jane Parkinson started their campaign bright and early on Saturday, when they overcame Worcestershire 3-1.
Next they faced Hampshire, relegated from the Premiership last year, and also triumphed 3-1.
This was also the scoreline against Devon, while the first day concluded with a 4-0 whitewash of Middlesex.
Despite some sore bodies, Oxon maintained their form on Sunday with a 3-1 success against Sussex.
This meant they needed just a draw in the final match against Wiltshire to take the title, but they again won 3-1 to make it six out of six and secure promotion to the Premiership.
Buckingham and Graham were unbeaten at men's doubles as were Gaines and Patrick in the mixed. Casey, playing with either Yeulet or Hicks, was unbeaten in the second mixed pair.
