Yorkshire 139-4 v Lancashire (17 overs)

Marchant de Lange managed to survive the hat-trick ball though.
Yorkshire 120-4 v Lancashire (16 overs)
Harry Brook takes a single to mid-on and reaches 50 off 35 balls.
Yorkshire have lost Gary Ballance, who was stumped off Matt Parkinson for two in the previous over.
Durham 115-4 v Leicestershire (15 overs)

Somerset 118-5 (14 overs) v Middlesex
Somerset struggling to build a big partnership in their innings having lost in-form Devon Conway and Will Smeed in successive overs earlier.

Worcestershire 48-1 v Derbyshire (5 overs)
A clean opening for Worcestershire in Derby until now, and a first wicket for Derbyshire's new signing Jade Dernbach on his debut.
The former England bowler's arrival on loan from Surrey for the final four games of the season was announced earlier today and he's straight into the action, as Worcestershire's Australian batsman Riki Wessels is out for 17 after a catch by Luis Reece.
Hampshire 48-3 (6 overs) v Gloucestershire
Plenty to interest both sides at the Ageas Bowl after the first six overs of Hampshire's innings.
The hosts are 48-3 having lost the wickets of skipper James Vince (13) and overseas players D'Arcy Short (17) and Colin de Grandhomme (1) inside the powerplay overs.
Gloucestershire will be very pleased with that return having lost the toss earlier.
Yorkshire 107-3 v Lancashire
Adam Lyth isn't happy with his execution of that stoke. He attempts to drive Luke Wells but the ball slides across the face and it's comfortable catch for Alex Davies, ending a stand of 77 with Harry Brook.
Notts 116-4 v Birmingham (13 overs)
This could be an important breakthrough at Edgbaston.
Notts have been keeping the scorecard ticking over nicely, but Birmingham's Jake Lintott jumped for joy after Notts' Ben Slater was caught out for 18 off the bowling of Will Rhodes.
That introduced Steven Mullaney, who Rhodes dives to catch out for just 2 after an awkward bounce.
Kent 44-2 (5.3 overs) v Surrey
Image source, Rex FeaturesZak Crawley falls for a spritely 24 off 16 balls just as he looked in danger of giving Kent a big platform and taking the game away from Surrey.

Yorkshire 107-2 v Lancashire (13 overs)
Yorkshire opener Adam Lyth reaches his second T20 fifty of the season with a lofted drive for four off Luke Wood. It's the fifth of his innings, to go with two sixes. Lyth made 51 not out against Leicestershire on 15 June. A better over for the Vikings.
Yorkshire 97-2 v Lancashire (12 overs)
A good over by Tom Hartley until he drags one down short and Harry Brook is able to pull it away to square leg for four. Seven from it and Yorkshire's strike-rate is now a shade over eight an over.
Yorkshire 90-2 v Lancashire (11 overs)
A new Matt Parkinson over and Harry Brook is immediately down the pitch to loft for six over long-on.
That should have been it for Adam Lyth as Parkinson turns one past the inside edge but Dane Vilas is unable to gather the stumping chance.
Durham 81-4 v Leicestershire (11 overs)
Leicestershire have started the second half of this innings with visiting bowler Gavin Griffiths reaching 50 wickets in his T20 career.
Graham Clark is the man caught but he made a very useful 40 that has helped restore confidence for Durham in this match after a shaky start against the excellent delivery of Naveen-ul-Haq.
Yorkshire 77-2 v Lancashire (10 overs)
Four to Harry Brook before Adam Lyth lobs one just out of the reach of a leaping Steven Croft. Brook pulls the spinner away for another boundary and that's a much better over for Yorkshire.Brook has 25 and Adam Lyth is 42 not out.
Sussex 201-7 v Glamorgan 21-0 (2 overs)
David Lloyd collects the first boundary of Glamorgan's run-chase from the bowling of Mitch Claydon - but it's a lucky one flying high over the Sussex wicketkeeper.
Lloyd makes better contact three balls later and picks up six over square leg before ending the over with another four.
Yorkshire 65-2 v Lancashire (9 overs)
Another good over for Lancashire as Tom Hartley restricts Yorkshire to singles with his left-arm spin. The Vikings need to press the accelerator.
