Too easy at the moment this for Derbyshire. They're getting short stuff and width from the bowlers.

Delightful little late cut from Godleman for four and he collects another boundary, far more fortuitously with a thick edge at Payne that flies just wide of short third man. The Bristol faithful looking rather ruefully into their beverages.

Would he have caught that if he was right on the rope the fielder there?

It was a flat hit, but that extra couple of paces back may have given him a chance.

Der 25-0published at 2 overs

2 overs

Target 136

That's not going to put much pressure on, 19 from it, including a bouncer that sails over everything and goes for six no-balls, while Reece, his blue rinse safely under his helmet, pulls one low and flat for the first six.

It may be that Godleman and Reece have said to each other, if we get this done quickly, it will get rid of any nerves in the dugout.

Australian AJ Tye is also cracked through the covers by the Derbyshire skipper.

I'm just wondering how Derbyshire approach chasing this sort of target, but Billy Godleman with his first two shots has just maybe indicated what the plan will be!

Godleman is not going to hang around, he steps down the wicket to thump one over cover for the opening boundary of the innings.

Derbyshire have two men who have passed 400 runs in the Blast this year, South African Wayne Madsen and skipper Billy Godleman have both made four fifties, left-hander Godleman making 92 against Worcestershire and half centuries in his last two Blast innings.

By far the lowest first-innings total of our four quarter-finals then, 24 runs short of the 159 Lancashire made against Essex.

No side at Bristol has scored 138 or fewer batting first and won the game.

Stats not on Gloucestershire's side.

Gloucestershire are going to start with their leading bowler this season, left-arm seamer David Payne, who helped them to the 50-over cup title at Lord's in 2015 and has 16 wickets from 12 innings in the Blast this year, with a best of 3-32 and another three-wicket haul in his last T20 outing at Sussex.

And Ravi Rampaul showed he can still deliver the goods.

"I've got it lads.." How about this for a caught and bowled from Matt Critchley...I thought he had revealed too much at first but it was the bar towel on the back of his trousers.

But Derbyshire gradually put the brakes on - and key man Klinger was run out for 15 in the ninth over.

The Gloucester openers made a good start after being put in and the hosts were 29-0 after only three overs.

Thanks Adam, well it has been a bowling night so far hasn't it? Some impressive four-over spells from the Derbyshire bowlers in that innings; Rampaul 1-23, Hudson-Prentice 2-26, Hughes 1-19 and Critchley 2-21. remarkable coloured pitch too, a sort of sage green. Let's take a look at some highlights.

Well then - are Derbyshire on their way to Finals Day or can Gloucestershire's bowlers pull rabbits out of hats?

The last two nights Jamie Lillywhite's had some batting masterclasses to describe as targets have been chased down with ease.

Are we in for more of the same this evening? Over the man himself to reveal all....

Gloucestershire will have to bowl out of their skins to keep their hopes alive.

Great last over from Ravi Rampaul for Derbyshire who perfects his yorkers at exactly the right time.

Gloucestershire stutter their way to just 135-7 as Ian Cockbain makes 45 not out off 34 balls but can't find another boundary.

Derbyshire's bowlers have given them a great chance to reach Finals Day for a first time - 136 will be the victory target.
