Eight T20 Blast matches
Wins for Surrey, Sussex, Durham, Birmingham Bears & Derbyshire
Hampshire, Kent & Worcestershire also win
Northants v Worcestershire 157-4
Worcestershire still going well at Wantage Road - until they lose Jake Libby to the first ball of the 18th over.
Ross Whiteley is stil there, well set on 23 as he is joined by Ben Cox, who loves these sort of situations.
Somerset 187-6 v Surrey 27-0
Two huge back-to-back sixes from Surrey and England's Jason Roy off the bowling of Marchant de Lange.
We're only in the second over. What a start.
Kent 140-4 v Middlesex
Jordan Cox comes down the track and lofts Nathan Sowter away for six to bring up a 35-ball 50. It's been an excellent innings for his side and with three overs to go, Kent will still be hoping to go beyond 170.
Leicestershire 2-1 v Derbyshire 209-6
When you are chasing over 200, you need a good start. Leicestershire don't get one as Scott Steel tries to smear Logan van Beek's opening delivery to goodness knows where and is caught by Billy Godleman at mid-off. A night to forget for Mr Steel.
Durham 181-8 v Yorkshire 10-0
England's Jonny Bairstow takes guard after a single by Adam Lyth and punches his first delivery through the covers off the back foot for four.
Three balls later, another four, but this one is less authoritative as tries to drive a wide one from Brydon Carse and only manages a thick edge.
Handy opening over for the Vikings, though.
Joe Weatherley c Plom b Neesham 42 (Essex v Hampshire 131-5)
Joe Weatherley won't reach his second ever T20 Blast half-century today.
New Zealand's Jimmy Neesham has a first Blast wicket of the season with Jack Plom taking a nice catch.
Two overs remain.

Jason Roy and Will Jacks will open for Surrey, chasing a tough 188 to win.
Other chases in the 18:30 BST games are also getting under way.
Notts 1-1 v Birmingham Bears 229-5
Alex Hales is cauight by Bears skipper Will Rhodes for a second-ball duck at Trent Bridge as Danny Briggs claims his 200th wicket in T20 cricket.
Brilliant start for the Bears - and deserved reward for the bravery of starting with a spinner.
The Bears must have had a scout at New Road the other night watching Hales and Joe Clarke tuck into the Worcestershire pace attack early on.
You'd have thought it would take a big knock from Hasles fopr Notts to get anywhere close tonight - but rhey still have big hitters like Clarke, Ben Duckett and new man in Peter Trego, who has already hit two sixes.
Northants v Worcestershire 132-3
Northants claim a third wicket in the 15th over as Brett D'Oliveira departs for 42.
Kent 114-4 v Middlesex
Jordan Cox and Jack Leaning have posted a 50 partnership for Kent at the Spitfire Ground after the home side had been reduced to 47-4. Cox is 35 not out, one more than his partner, and there are five overs to go.
Essex v Hampshire 124-4
Shot!
Joe Weatherley carves away a short one to move to 41 from 32 balls.
He's helped steady the ship for Hampshire after the loss of four early wickets.
16 overs gone.
Durham 181-8 v Yorkshire - end of innings
That's a lot healthier than seemed likely at one stage, and it's thanks to Brydon Carse, who makes 51 off 31 balls for Durham, with two sixes and four fours.
Carse was caught at long-on from the final ball of the innings as Jordan Thompson returned figures of 4-44 for the Vikings.
Notts v Birmingham Bears 229-5
All over for the Bears after knocking up their highest T20 score away from Edgbaston.
They have only twice before bettered their total of 229-5 - when they hit 242-2 against Derbyshire in 2015 and 231-5 against Northants in 2018 - but they were both at Edgbaston.
Ed Pollock (62 off 13 balls), Sam Hain (53 not out) and Carlos Brathwaite (44 off 18) were the stars, hitting 11 of the Bears' whopping 13 sixes between them.
Just 230 to win then for holders Notts, who have never been caned for a bigger total in 19 summers of T20 cricket.
Gloucestershire 177-7 v Sussex
A fine innings comes to a close as Gloucestershire finish on 177-7.
Glenn Phillips top-scored with 42. The hosts have set a mean total for Sussex to chase.
Leicestershire v Derbyshire 209-6 - end of innings
Image source, RexA fantastic final over for Derbyshire at Grace Road as they add 24 to boost their total beyond 200 for only the seventh time.
Matt Critchley hits two sixes and two fours off Ben Mike to finish unbeaten on 80 not out from 45 balls - his highest score in a T20 game.
Somerset 187-6 v Surrey
A big total from Somerset who finish on 187-6 against a very strong Surrey side. Tom Abell was the standout with 69 from 44.
We're in for some chase folks.
This is what it feels like to take a wicket when you are 16 years old and making your first-team debut.
Well bowled, Archie Lenham, who took 1-34 from his four overs for Sussex Sharks against Gloucestershire.
His victim? Gloucestershire skipper Jack Taylor.

Moeen Ali is second Worcestershire man out for 52 at Trent Bridge after four sixes and three fours
Big-hitting Ross Whiteley is next man in.
Gloucestershire 157-6 v Sussex
