Around 5,000 fans turned out at the home of cricket

Pro40 D2, Lord's: Middlesex 199-6 (38 overs) beat Derbyshire 196-9 (40 overs) by four wickets

Ed Joyce hit 68 as Middlesex celebrated Lord's first floodlit game with a four-wicket Pro40 win over Derbyshire.

Set 197 to win, Middlesex got home with 12 balls to spare with Andrew Strauss (43) and Ed Smith (32) also among the runs to keep hopes of promotion alive.

Tim Murtagh had earlier taken three wickets in five balls as Derbyshire slipped from 179-4 to 181-7.

Michael Dighton top-scored with 67, from 78 balls with 10 fours, while fellow Tasmanian Travis Birt made 47.

But Jamie Dalrymple broke the stand before Murtagh had Greg Smith leg before for 31, bowled James Pipe for a duck and did the same to Hassan Adnan for 21.

More than 5,000 fans were at the ground to see the temporary lights - which cost �20,000 to hire - switched on between innings.

Lord's has never previously held a game under lights because of complaints from neighbours.

But officials expect to install permanent floodlights, hoping to host games in the 2009 World Twenty20.

MCC secretary Keith Bradshaw said: "It's been a great success. We've learnt some things and we're going to do it bigger and better next time."

"We have a process with a view to the Twenty20 in 2009 because we believe it should be at the home of cricket."
