Yorkshire are hoping to end the monopoly on the Women's County Championship when they meet Sussex in a play-off on Sunday.
The White Rose are on the cusp to taking the title north 11 years on from their last triumph, with Sussex and Kent having each won the championship fives times since.
The teams, who finished first and second in Division 1, will meet at Campbell Park in Milton Keynes to determine who will be champions.
Although both sides have a similar record - six wins and two defeats - Yorkshire might hold a psychological advantage having beaten Sussex back in May.
In that game, Yorkshire made 179 for nine in their 50 overs with England star Danielle Hazell hitting 58.
Arran Brindle made a half century as Sussex went close but Yorkshire's bowlers remained disciplined and eked out a tense seven-run victory.
There are three other play-off matches which will decide promotion and relegation between the divisions.
Essex, who finished second bottom in Division 1, will need to beat Division 2 runners-up Somerset at Wellingborough if they are to avoid swapping places with the West Country outfit.
Durham, bottom of Division 2, will play Division 3 winners Netherlands at Moseley.
In the final match, Division 3 basement side Oxfordshire will meet Division 4 front-runners Suffolk at Wokingham.
