Surrey 152-6published at 19.4 overs
And again. Just one. This is an excellent final over from Toby Roland-Jones.
Surrey 151-6published at 19.3 overs
Just another single. No boundaries so far in this final over.
Surrey 150-6published at 19.2 overs
Slow ball from Toby Roland-Jones and Tom Curran is way early on it. The ball hits him on the side but they scamper a single through tho the wicket-keeper.
Surrey 149-6published at 19.1 overs
Toby Roland-Jones to bowl the final over. Can Surrey make 160?
Full toss but Sibley can only manage a single.
Surrey 148-6published at 19 overs
Sibley 17 Tom Curran 2
Decent over from Tim Southee. He bowls a wide but still only goes for six runs and claimed a wicket.
More drama. The Sky commentators are saying Middlesex are tight on finishing their overs in time but surely the delay around Kevin Pietersen's runner should be taken into account?
Pillans powerpublished at 19:54 British Summer Time 21 July 2017
Around the grounds
Seam bowler Mathew Pillans has been rather impressive for Leicestershire today as he has taken three wickets to keep Northants down to a final total of 165-8 after 20 overs.
A fine was to celebrate having his loan from Surrey extended by a further month.
Richard Levi top scored with 41 on his return to first-team cricket.
WICKETpublished at 18.3 overs
S Curran c Finn b Southee 1 (Surrey 144-6)
Sam Curran comes and goes with little impact. Tim Southee bowls it slow and wide and the left-hander skews the ball straight up in the air. Steven Finn mops up at short third man.
Notts crushing Derbyspublished at 19:52 British Summer Time 21 July 2017
Around the grounds
Image source, Getty ImagesThis could have been a closer match, but in the final over Derbyshire show why it's not.
Brendan Taylor - already having reached his half century - is dropped in the final over by Harvus Viljoen and Notts get an extra two, symptomatic of some poor fielding by the visitors at Trent Bridge.
He goes on to hit two more sixes and Notts finish on 227-3, their highest ever T20 score.
It's also the second highest total in T20 cricket by anyone against Derbyshire The highest score Derbyshire have ever made themselves before is 222-5...
WICKETpublished at 18 overs
Pope c Higgins b Malan 31 (Surrey 142-5)
Ollie Pope continues to up the scoring for Surrey but eventually falls to a catch in the deep off Malan.
Theat was not before the youngster managed to add three more boundaries to the total. A decent knock. 31 from 24 after a slow start.
Surrey 121-4published at 17 overs
Finally a boundary for Surrey! A heave from Ollie Pope but the crowd don't mind one bit. The kids are dancing in the stands again.
Four more! Not one from the textbook but Pope reverse hits Roland-Jones down to third man.

And here is the big talking point of the match so far.
Kevin Pietersen turned down a single, ran out Aaron Finch and it seems caused further damage to that troublesome calf.
The Aussie was not impressed. Just look at that stare back in KP's direction...
Birmingham set 180 to winpublished at 19:44 British Summer Time 21 July 2017
Around the grounds
Yorkshire have finished off their innings against Birmingham Bears, and have David Willey (70) to thank for their 179-5. Is that a getable total for the visitors at Headingley?
A 75-run partnership between Rob Keogh and Alex Wakeley put Northants back into the game against Essex - but the former was bowled by Matthew Pillans for 37.
At the halfway stage of Hampshire's innings against Essex, Michael Carberry (26) is doing his best to keep Hampshire in the game at 77-3
Image source, Rex FeaturesSurrey 115-4published at 16 overs
Sibley 11 Pope 12
The strike rates of both of these batsmen has dipped below 100. Malan is still bowling his part-time leg spin and Surrey can't get the ball to the rope.
Malan bowls a horrible half-tracker but Pope had already premeditated a scoop and can't any bat on it.
Still no major damage to Middlesex.
Surrey 111-4published at 15 overs
Tim Southee is back for a second spell. His experience is clear as he keeps on bowling slower balls into the pitch.
It is tough to bat out there now on this used pitch. Just two boundaries since the sixth over and one of those was as a result for a mis-field.
Taxi for Dawid Malan!
Will we get a game at Glamorgan?published at 19:34 British Summer Time 21 July 2017
The prospects of play still aren't great at the Swalec Stadium. As you can see from BBC Sussex's Adrian Harms' photo, many of the covers are still on.

Surrey 103-4published at 14 overs
Sibley 6 Pope 5
How many can Surrey get from here? 160? 200 looked possible earlier.
Another good over for Middlesex. Just six from it as Dawid Malan bowls his part-time leg spin.
Wessels outpublished at 19:33 British Summer Time 21 July 2017
Around the grounds
Image source, Getty ImagesRiki Wessels out for 110 and he gets a rapturous applause from all sides of Trent Bridge. He has basically put Derbyshire out of the picture in this match.
Elsewhere, since David Willey was run out, Birmingham Bears have slowed up the run rate and Yorkshire are currently 153-5 after just over 17 overs.
At Chelmsford, Hampshire opener James Vince helped himself to 29 runs before being caught behind off Ravi Bopara as the visitors are 66-2.
Surrey 97-4published at 13 overs
Ollie Pope is the new batsman. Roy, Finch, KP and Sangakkara are all back in the hutch. It's over to the Surrey's young guns.
Here is how Kevin Pietersen's bizarre innings ended.
He ended up with just four from nine balls, called for a runner and ran out Aaron Finch.
