Leicestershire 101-3 (8.3 overs) v Notts Outlaws 173
And Leicestershire lose another key figure in their run chase.
Arron Lilley is stumped by Tom Moores to give Calvin Harrison another wicket.
Colin Ackermann and Harry Swindells take up the challenge now.
Birmingham Bears 169-5 v Worcestershire 57-2 (8.3 overs)
Jake Libby (21no) and Daryl Mitchell (16no) regrouping well, if slightly slowly, for the Pears at Edgbaston.
Just as I say that, Mitchell goes for a big six and Kyle Mayers almost catches it on the boundary, one-handed, but can't hang on. Stops the six but it's four - and not a wicket.
Lancashire 199-5 v Durham 78-0 (6.0 overs)
Six overs gone. After the powerplay Lancashire were 75-0. Durham are 78-0.
We're in for an absolute thriller!
David Bedingham has 47 from 18, while Graham Clark has 28 from 18.
Middlesex 38-6 (8.3 overs) v Kent 157-8
This could be over pretty quickly at Lord's.
Kent well and truly in command as they reduce Middlesex to 38-6. Marcus O'Riordan dismisses Max Holden for nine to a smart catch on the boundary by Calum MacLeod.
Meanwhile in the stands, Middlesex legend Tim Murtagh is caught on camera downing a pint on command from some of the crowd. About the only thing that's gone right for the hosts in this innings so far!
Decent effort from Babar Azam tonight in the international T20.
Watch all the best shots from Azam's 85 off 49 balls as Pakistan post 232-6 in the first Twenty20 against England at Trent Bridge.

Somerset 181-5 v Glamorgan 35-2 (5.4 overs)
That earlier six would make Colin Ingram's highlight reel. This shot won't.
He attempts to pull a big one but gets his timing just off, I think he ends up hitting it off his own helmet and it loops up for the easiest caught and bowled Craig Overton will ever have.
Lancashire 199-5 v Durham 53-0 (4.0 overs)
A brilliant start from Durham who are making a go of this monster chase.
Graham Clark has 10. David Bedingham has 40 from 14!

Good response, this, from Glamorgan to losing the early wicket of Kiran Carlson.

He's now on 20 from just 8 balls.
Hampshire v Sussex 156-5 (18.1 overs)
Big effort from David Wiese but the ball doesn't quite carry over the longest part of the boundary.
Good finish so far from Hampshire.
Birmingham Bears 169-5 v Worcestershire 22-2 (4 overs)
Worcestershire might not make hay.
Lancashire 199-5 v Durham 21-0 (2.0 overs)

Very early days though.
Birmingham Bears 169-5 v Worcestershire 18-1 (3 overs)
Almost a second wicket for the Bears as Carlos Brathwaite tempts Jack Haynes into a slog.
Will Rhodes sprints and sprints and almost gets under it but the ball slips through his fingers. Tough catch that, good effort but not to be.
Will Worcestershire make hay from that narrow escape?
