In Cardiff, Glamorgan have chosen to bat after winning the toss and are unchanged from losing to Hampshire last time out.

Meanwhile, Middlesex have one change from their loss at Hants last night, with South African bowler Kyle Abbott coming in for James Harris.

Glamorgan: Rudolph (capt), Meschede, Ingram, Cooke, Wright, Wallace, Wagg, Parnell, Salter, Cosker, Hogan

Middlesex: Malan, Compton, Morgan (capt), Burns, Dexter, Franklin, Simpson, Roland-Jones, Abbott, Finn, Sowter.

Benny Howell has really managed to subdue the Kent batting line up, with the Gloucestershire man ending with figures of 3 for 18 in his four overs.

After being 54-1 and looking in a promising position, things are slightly stalling here for Kent with just five singles off that over from Tom Smith.

Are they going to be able to get a defendable score here?

James Vince has had a couple of lives now - he should have been run out but a fumble from non-specialist wicketkeeper Marcus Trescothick lets him off the hook. Max Waller concedes just four off the over.

16,000 people are ready and waiting at Headingley, where Lancashire captain Steven Croft has won the toss and opted to bowl. Jos Buttler will take a place in the middle-order alongside James Faulkner.

Joe Root and Gary Ballance have returned to the Yorkshire fold, while Glenn Maxwell will open alongside captain Andrew Gale. Gale is playing in his 100th T20 game for the county.

Yorkshire: Gale (capt), Maxwell, Root, Bairstow, Ballance, Leaning, Pyrah, Bresnan, Plunkett, Rashid, Fisher

Lancashire: Livingstone, Prince, Brown, Croft (capt), Buttler, Faulkner, Davies, Lilley, Parry, Edwards, Bailey

He might have got 96 in his last innings at home, but Sam Northeast is the next Kent player to be heading for the changing room as he is bowled attempting to cut the ball.

Two wickets in an impressive over for Benny Howell.

Very nice catch from Tom Cooper off Lewis Gregory's bowling accounts for Jimmy Adams, who looked as if he had suddenly decided to flick the switch and up the tempo. He mistimed that one though and it's two wickets down for Hampshire - Owais Shah's the next man in.

We're halfway through the Hampshire innings and it's 81-1 - what do you reckon? Decent platform or a few runs short of where they'd like to be? Plenty of wickets in hand though to hit out...

Darren Stevens is slightly unlucky here as he goes for another six off Benny Howell but is caught right on the boundary by Chris Dent.

Gloucestershire's bowlers doing a fine job at the moment in restricting the run rate.

After four overs without a boundary, Sam Northeast hits a maximum with the first ball of Jack Taylor's over.

Darren Stevens takes seven balls to trouble the scorers but adds eight with the final two balls as the Spitfires reach the halfway stage.

Great over from Jim Allenby as he records four dot balls - including the last three of the over - with some faultless yorkers. Just two runs off the over.

James Vince and Jimmy Adams look in good nick - the rough plan so far seems to be to hit the bad ball for four and then not take too many risks with the rest of the over. It's working well enough but the acceleration will need to come at some stage.

Perhaps knowing that Kent have been struggling to reach the rope, Daniel Bell-Drummond has gone for a big shot off Benny Howell and only found the hands of Ian Cockbain.

The visitors good start has come to a halt at the moment.

Bringing the pace off the ball is helping Gloucestershire who have slowed the scoring rate.

It's now 19 balls since Kent hit their last boundary...

Five runs off Benny Howell's first over off the evening for Gloucestershire who are managing to keep the run rate down at the moment.

Jack Talyor's off-spin now on for the visitors at Beckenham.

Somerset opener Chris Gayle owes his side a run...! A misfield sees him try to stop the ball with his feet - he ends up nutmegging himself and allows the second run to be scored by Jimmy Adams. A four off the final ball of the over from Adams takes it up to 11 off the over.

I'm not sure there is a more popular man in Taunton today than Craig Kieswetter.

The former Somerset opener, who announced his retirement this morning after suffering a horrific eye injury, led his side out ahead of the match against Hampshire.

First ball of the new over Tom Smith manages to out fox Sam Billings as he is getting into his stride, and former England wicketkeeper Geraint Jones whips off the bails to stump him.

Sam Billings is not letting Daniel Bell-Drummond have all the fun - he hits his second and third six of the game and moves onto 26 off 20 balls.

Gloucestershire tried a number of fielding changes during the over but Kent's power is too much at the moment.

Michael Carberry is the first Hampshire wicket to go as he holes out in the deep to James Hildreth off Sohail Tanvir's bowling. Somerset needed that...

Meanwhile the Chris Gayle fan club is in full effect in Taunton - the West Indies superstar is getting a round of applause every time he fields the ball!
