Yorkshire, whose last appearance in the final was in 1969, are in a buoyant mood after the two-wicket win over Lancashire in the quarter-finals.

Support for Glamorgan at Cardiff in their semi-final against Warwickshire will be equally vociferous, as the Welsh county have yet to win a knock- out trophy and their only appearance in a final was 18 years ago. Warwickshire, on the other hand, were within a match of completing the hat-trick of titles last season, losing the NatWest final to Worcestershire.
Nick Knight, their opening batsman who suffered a head injury during the fifth Test, is expected to declare himself fit.Reuse content
