More good fortune for Corey Anderson, who miscues to the fielder but is reprieved by a no-ball call for height, giving Somerset a free hit. The batsmen crossed and Lewis Gregory can only take one from it.

I think it's Sussex's game to lose - it is interesting to see the approach that Jofra Archer has taken if you look at how Worcestershire defended their total earlier today they went into the pitch quite a lot, bowled cutters, took the pace off the ball and tried to use the pitch as much as they could.

Archer is very fast who might be looking to go more into block hole yorkers and not give the batsman any width or any room to hit the ball.

Chris Jordan is up the next as a section of the crowd amuse themselves with an inflatable banana.

Full length just outside off stump is what he's looking for and Lewis Gregory can make nothing of the first four deliveries. Every dot ball is a hammer blow to Somerset's chances.

Gregory finally escapes the strike with a leg bye, leaving Corey Anderson to deal with the final ball - but it has the same result. No runs from the bat in that one - surely Somerset have too much to do now.

Jofra Archer has the ball. The required rate is almost 15.

Just three singles until the final delivery which Corey Anderson slams down the ground where a diving Delray Rawlins can only shovel it into the rope. Four runs - 62 from 24 needed.

No need to look so nervous Sharks fans...

Just three from the over, as well as Tom Abell's wicket. That's come at a very bad time for Somerset, who were just gathering some decent momentum - they need 69 from 30 balls.

Corey Anderson and Lewis Gregory have hit 50 T20 sixes between them this season - the Cider Boys need a few from them now.

Tymal Mills is back for his third over - and you can only imagine what he must be thinking as Jofra Archer is too casual at backward point and concedes a needless boundary.

Mills attempts a slower ball from the final delivery, but Anderson - who has changed his bat - lifts it over deep mid-wicket for his third six. Somerset need 72 from six overs - the partnership is worth 83.

David Wiese resumes and Corey Anderson cross-bats down the ground for two.

Wiese helps the Somerset cause with a couple of wides, but Anderson has to scurry to make his ground from the next as Chris Jordan's throw comes in from the deep.

Finally, Anderson gets hold of one and clears the rope at square leg for six before smashing the final delivery over long-on for another. Anderson has 27 and Tom Abell is on 46.

If Corey Anderson can get going I think we are in for a really big treat in this second half of this innings.

A couple of Tom Abell boundaries boost the total as Somerset's 100 comes up with eight overs to go. The required rate is heading towards 13 an over.

Corey Anderson throws the kitchen sink at Will Beer's first ball, but makes no contact. It should be an easy stumping but Michael Burgess fails to gather cleanly.

The next delivery comes off the top edge, but David Wiese cannot hold the catch as he dives forward in the deep. Two let-offs in two balls for Anderson.

Chris Jordan back into the attack and Corey Anderson is certainly giving it some welly, but the boundary riders prevent him finding the rope.

Tom Abell attempts a ramp shot but fails to make contact - and there is an appeal for a catch by the keeper from the final delivery, but the umpire says the bat struck the ground.

You don't actually know that you've touched the rope, you have an idea but don't know when you've let the ball go.

Another good over by Will Beer as Somerset are unable to penetrate the in-field. Sussex were 91-3 at the half-way point of their innings, so not much difference in that sense.

But do Somerset have someone to play a Luke Wright-style innings?

An anxious moment for Tom Abell as Laurie Evans takes a catch on the boundary edge and throws to Phil Salt before he steps back over the rope. The replay shows, however, that he trod on it as he took the catch, so it's six.

Abell celebrates the end of a productive over with a square drive for four - 25 from it.

Somerset 69-4 - target 203

There's a slog sweep by Tom Abell and he times it well, depositing Danny Briggs into the crowd. A reverse paddle and a lofted cover drive follow and both find the boundary. This is more like it for Somerset.

Corey Anderson is now at the crease and you feel he will have to 'go big' if Somerset are going to be competitive for the remainder of their innings.

Will Beer is the new bowler and one to long-on by Anderson takes the total to 50. It's a good over, though, which yields six singles and nothing more.

David Wiese made 52 off 29 balls in Sussex's innings and now it's his turn with the ball.

He lopes in, but James Hildreth lofts the ball over his head for four and also drills the final delivery past a diving mid-on fielder for another boundary as he goes past 400 T20 Blast runs for the summer.

Better over for the Cider Boys.
