Birmingham Bears 63-5 v Worcestershire (8.5 overs)
Rob Yates arrives - and then goes six balls later, chipping up a pretty tame caught and bowled to Brett D'Oliveira.
Carlos Brathwaite, what you got?
Sam Hain (31no) needs some help here. He needs a partner.
Lancashire 101-1 v Durham
Finally a breakthrough after 8.1 overs.
Finn Allen mistimes a slower delivery and loops one into the air, being caught on the long-on boundary.
A fine knock comes to a close. 66 runs off 28 balls. Alex Davies is the new man in.
Birmingham Bears 56-4 v Worcestershire (7.4 overs)
Boom. Back past bowler Ed Barnard and rising, rising, rising.
Kyle Mayers then tries to repeat the feat three balls later but doesn't get hold of it and Brett D'Oliveira takes a pretty regulation catch.
Quickfire cameo debut that, departing for 13 but you fancy Birmingham needed him to get a few more.
Lancashire 101-0 v Durham (8 overs)
Incredible. After just eight overs Keaton Jennings (28 not out) and Finn Allen (66 not out) bring up the 100 partnership.
What a start. But hang on...
Somerset 67-2 v Glamorgan
Will Smeed tries to up that Somerset rate back to where it was a few overs ago but he just holes out in the deep as Timm van Der Gugten clings on.
Sussex 4-1 v Hampshire (0.2 overs)
Early wicket!
Sussex and England opener Phil Salt falls second ball off the bowling of Liam Dawson.
Ravi Bopara is in at number three.
Leicestershire v Notts Outlaws 86-2 (7.4 overs)
The Joe Clarke show is over at Grace Road - much to Leicestershire's relief I'm sure!
The same combo that did for Alex Hales does for Clarke as Arron Lilley takes the catch in the deep off Colin Ackermann.
Clarke 57 off just 27 balls, including five sixes.
Somerset 67-1 v Glamorgan (8 overs)
Somerset's run rate has slowed slightly but that was still a very decent powerplay for them.
Lancashire 87-0 v Durham (7.0 overs)
A brilliant 50 for Finn Allen comes up off 23 balls with a six.
It's his fourth half-century of this year's T20 Blast campaign.
A great knock and we've only had seven overs.
Leicestershire v Notts Outlaws 78-1 (7 overs)
Some pretty devastating hitting from Joe Clarke.
He reaches 50 from just 24 balls with four fours and four sixes.
Two of those maximums came in the same over off Ben Mike straight down the ground over long-on.
Brilliant display.
Hampshire v Sussex 4-0 (0.1 overs)
Our final fixture tonight gets going with Sussex batting first.
Phil Salt starts us off with a four.
A reminder, Hampshire have already played - and won - early today, with an 18-run victory over Essex.
Lancashire 75-0 v Durham (6 overs)
Not a bad power play for Lancashire.
Finn Allen has 45 from 19. Keaton Jennings is on 23 from the same amount of balls.
Durham need quick wickets to get back into this game.
Middlesex v Kent 93-2 (10 overs)
Kent are looking set for an imposing total at Lord's at the halfway stage of their innings.
Heino Kuhm has 41 off 32 balls in a partnership worth 40 for the third wicket with Harry Finch (15 not out) so far.
Birmingham Bears 36-3 v Worcestershire (4.4 overs)
Wickets becoming a concern already for Birmingham Bears as skipper Will Rhodes is caught by Ish Sodhi for Dillon Pennington's second wicket.
Recent signing Kyle Mayers in. Big contribution needed from the West Indies man.

That's HUGE!
Finn Allen takes on Matty Potts who bowls one far too short.
A massive swipe from Allen who makes great contact and sees the ball fly into the stands. He's on to 44 not out.
Leicestershire v Notts Outlaws 62-1 (6 overs)
No signs of slowing down for Notts despite losing Alex Hales midway through the powerplay.
First six overs done sees them move on to 62-1 with Joe Clarke rattling off 37 from just 20 balls so far.
Could be a long couple of hours in the field for Leicestershire at this rate.
Somerset 52-1 v Glamorgan (5.3 overs)
And those were Steve Davies' final runs of the evening.
The next edge doesn't go as planned, straight to wicketkeeper Chris Cooke.
Good opening stand from the visitors though.
Somerset 52-0 v Glamorgan (5.2 overs)
Somerset's Blast destiny is in their own hands - win their final two group games and they'll be in the last eight.
And they are flying at Sophia Gardens, bringing up the half-century after 32 balls against Glamorgan as Steve Davies edges one away for four.
Lancashire 51-0 v Durham (4.2 overs)
Change of attack as slow left-armer Liam Trevaskis takes the ball.
Keaton Jennings instantly hits him for six first ball.
50 up for Lancashire without loss. Top start.
Birmingham Bears 30-2 v Worcestershire
Birthday boy Sam Hain follows a lovely cover drive for four a few balls later with a cheeky scooped six over the wicketkeeper that drops just over the ropes.
Decent recovery here from 7-2 for Bears.
