Somerset 99-2 v Surrey 195-9

Tom Abell will on strike at the start of the next - he has 39 and Tom Banton is 42 not out.
Yorks 117-0 v Leics 195-5
This game is starting to run away from Leicestershire like a shopping trolley which escapes your grasp at the top of a steep slope.
Two fours for Dawid Malan off Josh Hull takes him to 61 not out and Adam Lyth has 52.
This is now a record Yorkshire opening partnership against the Foxes in T20 cricket - beating the 116 by Andrew Gale and Phil Jaques on the same ground 11 years ago, and by Lyth and Tom Kohler-Cadmore at Leicester in 2019.
Northants 73-5 (9.1 overs) v Lancashire 204-7
Luke Wells sends down a half-tracker, but Justin Broad gets it wrong and picks out Daryl Mitchell at long-off.
A fifth wicket for Lancashire and they will fancy their chances from this position. A lot depends on T20 specialist Chris Lynn for Northants.
Sussex 183-6 (20 overs), Hampshire 13-3 (2.1 overs)
Hampshire's start goes from bad to worse as Ben McDermott follows James Vince and Toby Albert back to the hutch.
He is leg before wicket to Arii Karvelas.
Durham 178 v Derbyshire 104-2 (11.1 overs)
Wayne Madsen had brought up a 50 partnership with Luis Reece to get his team over 100 but he falls to Paul Coughlin to offer Durham some hope.
The home side need a few more of those and quickly.
Somerset 94-2 v Surrey 195-9
Tom Abell is opening up now for Somerset.
A ramp and square drive bring him boundaries off Tom Lawes.
Back to back sixes off Sunil Narine follow in the next over - the ninth - and he is 36 not out from 19.
Tom Banton ends it with four to progress to 40 not out.
Essex 23-2 (2 overs) v Glamorgan
Image source, Rex FeaturesFrenetic stuff at Chelmsford as Feroze Khushi has reached 20 in two overs after both Robin Das and Michael Pepper had fallen to first-ball ducks in Jamie McIlroy's opening over.
Das was caught on the midwicket fence and Pepper was out trying a ramp shot - perhaps not the wisest shot to your first ball!
Sussex 183-6 (20 overs), Hampshire 12-2 (2 overs)
Dodgy start for Hampshire.
Three wides but two wickets in successive balls for Brad Currie - as he gets skipper James Vince and Toby Albert, but just misses out on a hat-trick with a legside wide that could also easily have been a stumping.
Durham 178 v Derybshire 88-1 (10 overs)
Derbyshire reach the halfway point, at almost halfway to their total and with nine wickets in hand.
What's more, they have two batters nicely in, in Luis Reece and Wayne Madsen.
The crowd at Chester-le-Street is a bit quiet right now.
Yorks 104-0 v Leics 195-5
Before this innings, Adam Lyth's highest score in this year's Blast was 32 - but he reached 50 off 28 balls with a four followed by a six off Rehan Ahmed.
Partner Dawid Malan strikes a six of his own to move to 49 not out and a single brings him his fifth half-century of the competition from 31 balls. He is Yorkshire's Mr Consistency.
Another 92 needed from their 10 remaining overs.
Somerset 64-2 v Surrey 195-9
Time for Sunil Narine's leg-spin at Taunton and Tom Banton sweeps his second delivery over square leg for six.
There is also a boundary to long leg in that over for the right-hander, who is 32 not out off 20 balls.
Yorks 77-0 v Leics 195-5
Spin at both ends at the moment from Leicestershire.
Another boundary for Adam Lyth in the eighth over, bowled by Colin Ackermann, but Yorkshire's required rate is now almost 10 an over.
Essex 1-2 (0.3 overs) v Glamorgan 175-6
What a start from Glamorgan and Jamie McIlroy. He is on a hat-trick after three balls!
Northants 47-4 (5.4 overs) v Lancashire 204-7
Image source, Getty ImagesSix and out for Saif Zaib as he is caught down legside off Jake Blatherwick with England white ball captain Jos Buttler taking the catch.
Zaib had hit the previous ball for six!
Germany international Justin Broad comes to the crease.
Durham 178 v Derbyshire 62-1 (7 overs)
Durham have indeed struck with Harry Came going for 34 and veteran South Africa left-hander Wayne Parnell the man with the wicket.
Derbyshire need 117 off 13 overs at exactly nine an over.
Somerset 42-2 v Surrey 195-9
Tom Abell finds the third man boundary with a thick edge off Chris Jordan. Another four, superbly driven away by Tom Banton, ends the fifth over and Somerset require 154 more from 90 balls for their eighth win in nine games.
Northants 35-3 (4 overs) v Lancashire 204-7
Image source, Getty ImagesA quick recap of Luke Wood's incredible three-wicket over.
1st ball - leg bye
2nd ball - Emilio Gay caught
3rd ball - Three runs (one and given as a no-ball)
Free hit - Ricardo Vasconcelos hits it for six
4th ball - Brilliant one-handed return catch by Wood
5th ball - David Willey caught behind
6th ball - no run
Three wickets, 10 runs and a whole heap of drama!
Sussex 183-6 (20 overs) v Hampshire
Sussex have set a decent target at Hove, largely set up by the 98-run third-wicket stand between Oli Carter (64) and Ravi Bpoara (30).
Yorks 56-0 v Leics 195-5
Four runs to Dawid Malan off Naveen-ul-Haq and Yorkshire reach 50 in the sixth over. Adam Lyth adds one of his own and he is 19 not out, with Malan on 35.
Bears 196-5 (20 overs), Worcestershire 175-6 (20 overs)
The Bears beat the Pears in the big derby at New Road.
Birmingham Bears go top of the North Group as they beat Midlands neighbours Worcestershire by 21 runs.
They edge above Notts who did noy play tonight, while it is a fourth straight defeat for the hosts.
A late cameo from Usama Mir (three sixes and a four in his 32, to match his T20 career-best) is not quite enough.
The Bears complete their first win at New Road since 2017 - and will hope to make it a double when the two sides meet again at Edgbaston a week tonight.
But, before then, Worcestershire go to Leicester on Sunday, then the Bears head to Chester-le-Street to face Durham this Tuesday night.
