Live coverage from the NatWest Trophy quarter-final match between Yorkshire and traditional rivals Lancashire. This year, Lancashire are on course for that unprecedented clean sweep of all four domestic cricketing trophies that so narrowly eluded Warwickshire last year. Plus, regular roundups from the other grounds. Warwickshire will play Derbyshire, for whom the competition represents the only hope of success in what has been a dismal season, while championship contenders Northamptonshire have put aside poor one-day form to earn a tie against Gloucestershire. Meanwhile, Middlesex face a difficult game against Glamorgan at Cardiff. Introduced by Tony Lewis.
