Usman Arshad tightens things up as he goes for just six off his first over, including a boundary from Tom Kohler-Cadmore.

The Worcestershire opener is in imperious form it seems.

Worcestershire 30-1 v Durham (3 overs)

Tom Kohler-Cadmore looks in the mood here. The Worcestershire opener smashes Paul Coughlin for back-to-back maximums to finish the over.

Wonderful striking from the 21-year-old, who moves up to 24.

Barry McCarthy picked up a five-wicket haul in Durham's last County Championship game, but T20 cricket is a different kettle of fish.

Tom Kohler-Cadmore hits the paceman for back-to-back boundaries and Worcestershire are away.

After a cautious start, Worcestershire captain Daryl Mitchell finishes the over by driving Paul Coughlin for a magnificent straight drive for four.

Mitchell will just play his normal game here, while the others can blast it around him.

Worcestershire openers Daryl Mitchell and Tom Kohler-Cadmore make their way to the middle at New Road alongside the Durham Jets team.

The Rapids have won three T20 matches in a row against Durham Jets. Can they make it four this evening?

It's 12 years since Glamorgan reached the semi-finals of the domestic T20 competition, but they have pulled off quite a coup for this year's tournament by signing South African paceman Dale Steyn.

Still in many people's eyes, the best fast bowler in world cricket, the 32-year-old has taken 639 wickets for the Proteas in all forms of the game - including 58 in 42 T20 internationals.

Steyn will play in Glamorgan's first seven games - starting at The Oval against Surrey next Thursday - before handing over to Australian T20 specialist Shaun Tait.

"I'll do all I can to give the team the best possible start," he said.

Nothing much has changed from last year - the 18 teams are separated into two groups of nine, North and South.

Each side will play 14 group games with the top four from the North and South qualifying for the quarter-finals.

Finals Day takes place at Edgbaston, a weekend earlier than 2015, on 20 August.

In the 13 years since Twenty20 cricket made its arrival in England, there have been ten different winners.

Surrey were the first in 2003, Lancashire picked up last year's trophy and Leicestershire have won it three times.

But which team will win the 2016 T20 Blast?

Worcestershire and Derbyshire fans, is this the year you make Finals Day for the first time? Will Lancashire retain their title?

Two months ago, Mitchell Santner was a member of the New Zealand team beaten by England in the semi-finals of the World T20.

The 24-year-old all-rounder had a first taste of county cricket when he played in Worcestershire's Championship game against Glamorgan - and is now looking forward to helping the Rapids in the T20 Blast.

"It should be a good experience and hopefully I can help Worcestershire out with a few wins. They have done pretty well in the last few T20 competitions," he told BBC Hereford & Worcester.

"T20 cricket these days is played on pretty flat wickets, but I am excited. I talked to Colin Munro and Mitchell McClenaghan, who both played for Worcestershire, about what to expect, what the wickets are going to do.” 

News from the middle at New Road is that Durham have won the toss and asked Worcestershire to bat.

Worcestershire Rapids have New Zealand duo Matt Henry and Mitch Santner in the side. Captain Daryl Mitchell and Tom Kohler-Cadmore will open the batting.

Durham Jets are without Paul Collingwood so Graham Clark comes into the team. 

Worcestershire: Mitchell, Kohler-Cadmore, Clarke, Whiteley, Santner, D'Oliveira, Cox, Leach, Barnard, Henry, Shantry.

Durham: Stoneman, Mustard, Jennings, Clark, Richardson, Pringle, Borthwick, MacLeod, McCarthy, Arshad, Coughlin.

We'll have to wait a little bit longer to see him, but the World Boss, or is it the Universe Boss, will be back for Somerset in this year's competition.

The last time we joined you for T20 Blast action was back in August for Finals Day 2015, when Lancashire claimed their maiden title, having finished runners-up on two previous occasions.

Alex Davies' 47 from 26 balls led the way for Lightning as they set Northants 167 to win at Edgbaston.

The Steelbacks looked on track to chase down Lancashire's target at 74-2 from 10 overs, but they could not up the run rate and fell 14 runs short of the target.

Earlier, the Red Rose had cruised to a six-wicket win over Hampshire, and Northants chased down defending champions Birmingham's 131-6 with two overs to spare in the other semi-final.

This year, Lancashire will be looking to make it to their third consecutive Finals Day appearance, while Worcestershire and Derbyshire will attempt to end their runs as the only teams never to make the last four.

Here's how the opening night of the 2016 T20 Blast lines up:

17:30 - Worcestershire v Durham - New Road

18:30 - Gloucestershire v Sussex - Bristol

18:30 - Leicestershire v Northamptonshire - Grace Road

18:30 - Nottinghamshire v Birmingham Bears - Trent Bridge

19:00 - Kent v Somerset - Canterbury

When you think of a typical Friday night, what does it entail? A fish and chip supper? A nice glass of red to unwind after a hard working week? Maybe a film with a loved one?

Well, what about 20-foot high flamethrowers and lads dressed as beer bottles? Because that's what tonight's T20 Blast could serve up.

It's back, it's bigger and better than ever, and we've got live text and radio coverage from all of the opening round of games coming up.
