Despite losing partner Daniel Bell-Drummond, Joe Denly has carried on carting the Glamorgan bowlers around the park.

Craig Meschede is the latest bowler to suffer at Denly's hands as he's struck for a huge six as Kent take 15 from his over.

Sam Northeast can barely get hold of the strike but his quick running has kept the score ticking over.

Brute force from Rory Burns sees him clear the straight boundary from a free-hit offered by Jim Allenby. He's then dropped by Jamie Overton, who is given some stick by the home crowd after spilling an earlier chance.

Just to compound Somerset's misery, Jason Roy lofts a superbly-timed straight hit back off Max Waller that goes well back into the OCS Stand.

Surrey have moved past 150, the rate is up above 10 runs an over and Surrey could be on course for a score in excess of 200.

Roy, meanwhile, will be eyeing three figures. He's 89 not out.

Glenn Maxwell's miserable campaign continues as he is caught by David Willey off Steven Crook.

The over before Alex Lees went for 46 - his highest T20 score for Yorkshire this season - after he was caught and bowled by Graeme White.

It wasn't the quickest innings, taking 42 balls with two boundaries and one six, but considering Yorkshire were two wickets down inside the first three overs, it was what the side needed.

Yorkshire will do well to reach 140 from here.

Lancashire have been pegged back again by Birmingham.

Jeetan Patel's grabbed his second wicket of the evening and has gone for just seven runs off three overs.

Luke Procter's the latest man to succumb for the visitors after a fifth-wicket partnership of 41 with Steven Croft as they continue to struggle against the North Group leaders.

Nottinghamshire have recovered well from the loss of Alex Hales at Durham, with Michael Lumb leading the way on 26.

Riki Wessels has also shown plenty of attacking intent as the Outlaws have raced to 54-1 at the end of their first six overs.

Big big game at Chester-le-Street tonight.

Sussex have made a breakthrough after a strong start from Hampshire at Hove.

Michael Carberry drives a touch too early at a ball from Chris Liddle and Ollie Robinson dives forward to take a smart catch at mid-on.

BBC Radio Derby's Iain O'Brien at the County Ground:

"It's not been Derbyshire's best start in the competition. They've averaged 51 in the powerplay this season but they'll be hard pressed to find that here."

Derbyshire have their work cut out to save this game, as Worcestershire have taken a third wicket at the County Ground.

Shiv Thakor is the latest man to fall, caught by Brett D'Oliveira from the bowling of 19-year-old seamer Ed Barnard.

The Falcons are 27-3 at the end of the powerplay.

Former captain and newly-appointed Essex cricket committee chairman Ronnie Irani would have been happy with the Eagles' start, but not the way that Middlesex have now started to fight back.

Graham Napier's over has disappeared for 16, including a sweet strike down the ground from Nick Gubbins for a maximum, moving him to 26 from 16 balls.

John Simpson has 17 from 11 at the other end.

10 overs have been bowled in Lancashire's innings at Edgbaston and they're in need of some urgent impetus.

Luke Proctor and captain Steven Croft are trying to rebuild the damage from 34-4 amid some tidy bowling from the hosts.

Durham's tidy start is rewarded when Nottinghamshire's Alex Hales attempts to hammer John Hastings over the leg side boundary, but instead picks out Scott Borthwick in the deep.

The hosts have taken a mere 13 runs from their first three overs.

Jason Roy has displayed the kind of form that earned him an England call after that early let off, going to his half-century with an easy two off Jim Allenby.

He then scoops the seamer for another three runs to keep the Surrey momentum going as they reach the halfway stage of their innings.

Ah. Just as Yorkshire were mounting a tiny recovery, with Jonny Bairstow smashing Graeme White for six, the stand-in captain has fallen.

He's tries to launch Josh Cobb's spin for six but instead lofts a catch to Ben Duckett at deep mid-wicket.

He's replaced by Glenn Maxwell, another international star who has had a quiet season with the bat.

Wow, the T20 stars are falling like flies at the moment!

Somerset look relieved to have finally ended a Surrey opening stand of 84 that had been threatening to take the game away from them, even at this early stage in the game.

It was a leg break from Max Waller that did the trick, turning between bat and pad of the left-handed Kumar Sangakkara, allowing New Zealander Luke Ronchi to complete a simple stumping.

Joe Denly and Daniel Bell-Drummond aren't hanging around down in Tunbridge Wells.

Michael Hogan's first two overs have cost 26, with Denly smashing five boundaries and one six off the right armer's bowling.

Dean Cosker has fared slightly better, with his first over costing 11 runs. Kent are looking to get this over as quickly as possible.

The nightmare start continues for Lancashire at Edgbaston.

Birmingham Bears have claimed four wickets now as Karl Brown is the latest man to depart trapped lbw by spinner Jeetan Patel.

Think they might need a few more runs on the board to keep Brendon McCullum quiet.

Worcestershire are off to the perfect start at Derbyshire, as Joe Leach finds the edge of Hamish Rutherford with his second delivery.

Tom Kohler-Cadmore makes no mistake in the slips, and Rutherford has a long walk back to the pavilion.

Leach's dream over continues as he bowls Chesney Hughes with the final ball.

Steady start at Hove from the visitors Hampshire as James Vince tucks in to Michael Yardy's opening over with a couple of fours.

What a start for Essex as Reece Topley gets one to leave Dawid Malan and his attempted drive is easily taken by wicket-keeper James Foster.

Essex are desperate for a win to keep their quarter-final hopes alive.
