Derbyshire and Essex have progressed through to the final of the Twenty20 Floodlit competition.
The second leg of the semi final between Derbyshire and Glamorgan at Derby produced a first for cricket as it was decided in extra-time after Glamorgan had won the full match to make it one leg each. The four-over-per-side decider went the way of Derbyshire as they defend 43, with Tom Lungley and Jake Needham producing tight overs, and restricted Glamorgan to six off the final when 11 were needed. Glamorgan had sealed the full match with five balls to spare after Richard Grant's 50 and a rapid 34 from Ryan Watkins enabled them to chase down 157. Derbyshire's innings was based around Travis Birt's 51 and although it wasn't enough, they held their nerve in extra time.

Essex were left waiting for news of their final opponents after a comfortable six-wicket victory over Sussex at Chelmsford. Sussex failed to capitalise on an excellent start given to them by Chris Adams (51 off 23 balls) and Mike Yardy (36 off 33 balls) as they lost wickets regularly in the closing stages. Ryan ten Doeschate picked up wickets in each of his four overs to claim 4 for 24 as Sussex were pegged back to 181 for 8. Alastair Cook, drafted into the Essex side ahead of England's ODI series, gave his side a rollicking start with 38 off 20 balls. After a flurry of wickets, Ravinder Bopara (58 off 35 balls) and ten Doeschate (38 off 20 balls) hurried their team to victory with 10 balls to spare.

Essex meet Derbyshire in a two-legged final on September 13 and 15, with the first leg at Chelmsford. Sussex and Glamorgan feature in a third-place play-off over the same nights.
