Glenn Maxwell takes two off the first ball of the 11th over, but hits Ollie Freckingham's third ball straight to Jigar Naik, who takes a fine catch.

The Foxes are right in this.

Daryl Mitchell was leading the charge for Worcestershire at New Road - but a desperately unfortunate run-out has seen him dismissed.

Mitchell was anchoring the innings nicely, with 34 from 26 balls, but Josh Cobb deflected a straight drive from Colin Munro on to the stumps and Mitchell is on his way.

A Northants total of 193 is looking a big ask.

Hampshire badly need to find a way to take a wicket to stem the scoring rate or face the prospect of having to chase a big target at Chelmsford and off-spinner Will Smith finally induces an error from Essex opener Mark Pettini, who has hit three sixes and nine fours in his 74 off 45 balls.

Jesse Ryder is still there at the other end, though, having brought up his half-century off only 28 balls in the previous over.

BBC Sport Wales's Dafydd Pritchard at the Swalec Stadium: "As the pace has been taken off the ball and the brakes applied to Surrey's run-rate, the volume has certainly risen at the Swalec Stadium.

"A healthy crowd of 6,000 or so are basking in a Surrey collapse as the visitors have folded from 104-1 to 131-6, with all six wickets falling to spin."

Jonny Bairstow has the field spread as he smashes a six and a four in successive Ben Raine balls to bring up the 50-run partnership with his skipper, Andrew Gale.

But Raine has his revenge next ball, flattening the stumps as the wicketkeeper goes for another big hit. Three maximums in his 37 from 22 balls.

Just the small matter of Glenn Maxwell to cope with now for the Foxes bowlers.

Jim Allenby and Johann Myburgh both bring up their half-centuries in the space of a few minutes. Middlesex have managed to bowl the odd tight over, but the lack of wickets means this match is drifting away from them increasingly quickly, and neither opener has looked in much trouble so far.

Lancashire captain Steven Croft keeps the Bears guessing, and succeeds in slowing the scoring rate, with frequent bowling changes and Varun Chopra eventually loses patience and lofts left-arm spinner Stephen Parry straight to Arron Lilley at long-off. It is a major setback for the visitors, who are looking to repeat their victory over Lancashire's in last year's final.

Somerset may be lacking their World Boss now, but you have to fancy them from their current position. Openers Jim Allenby and Johann Myburgh are going about things in assured fashion and Somerset are almost halfway there already.

Jason Roy's departure has led to a bit of mini-collapse for Surrey against Glamorgan.

Vikram Solanki and Gary Wilson both quickly followed Roy back to the pavilion and now their innings is in danger of falling well short of what seemed likely, with 118 on the board and just four overs remaining.

We're now under way in our final match, between Derbyshire and Nottinghamshire, which means all eight of this evening's T20 Blast matches are in progress!

Yorkshire took only 33 runs from their powerplay as Ollie Freckingham and Niall O'Brien come into the attack for the hosts.

But England wicketkeeper-batsman Jonny Bairstow is finding his feet. He smacks a six, four and single from the last three balls of O'Brien's first over, and then a six from Jigar Naik's opening delivery.

Andrew Gale also helps himself to a four as Naik's first over goes for 14.

Oliver Robinson takes the wicket of former England wicketkeeper Geraint Jones with an artful piece of deception, but the final over of the innings goes for 11. A competitive total from Gloucestershire - how will George Bailey and co get on in their reply?

Essex are going like a train at Chelmsford and after hitting a six off spinner Danny Briggs, Mark Pettini brings up a 31-ball half-century with a single in the same over, his third of the season. Jesse Ryder has had far less of the strike, but has already cleared the rope twice.

BBC WM 95.6's Mike Taylor: "That went so high and in the strong wind it was a difficult one to judge. It was an outstanding running catch by Steven Croft."

Bears skipper Varun Chopra collects four over mid-wicket and then flicks another boundary through fine leg, but there is disappointment for the Old Trafford crowd as partner Brendon McCullum attempts a straight six from the final ball of Jordan Clark's over, but gets underneath the ball and the catch is superbly taken by home skipper Steven Croft.

Jason Roy's impressive innings comes to an end for 61 off 47 balls against Glamorgan in Cardiff, as he's caught by Michael Hogan off the bowling of Dean Cosker.

An eye-catching knock by the England ODI and T20 opener, though, clearly returning from his international duties with a fair dose of confidence.

England wicket-keeper Jonny Bairstow is at the crease as Leicestershire continue their brilliant start, Ben Raine trapping Andrew Hodd leg before for two.

Bairstow is under the cosh immediately as he survives an lbw appeal from Raine from his first ball and a caught behind enquiry from his second.

Clint McKay then restricts the visitors to just four from the next over. Game on?

Meanwhile, Tom Kohler-Cadmore and Daryl Mitchell have shared 36 runs for the second wicket as Worcestershire look to recover from the early loss of Moeen Ali.

BBC Coventry & Warwickshire's Clive Eakin: "I don't think McCullum's got hold of one yet."

Well, he's not doing too badly. He's already notched up four boundaries for the Bears and has 18 off 12 balls.

Solid start from Somerset in their reply at Uxbridge, with Jim Allenby hitting three boundaries off the third over. With a required run rate of 8.6 an over, a few more of those and Somerset will be more than happy.
