In the first round at Derby, Derbyshire batsmen Alan Hill and Iain Anderson put on a then record partnership for any wicket in limited overs cricket.
The semi-final between Worcestershire and Sussex at Worcester took three days to complete due to bad weather.
At The Oval, Lancashire won by 4 runs Trevor Jesty scored 112 and was man of the match for Surrey.
This was the last big game for Lancashire, and former West Indies, captain Clive Lloyd who retired at the end of the season.
