From a Yorkshire point of view, that's a bit more like it. No boundaries off Steven Patterson's fifth over of the day, just four singles.

We have a change at the other end as 17-year-old Matthew Fisher replaces Tim Bresnan.

Chris Dent has clearly seen what his partner is doing and wants a piece of the action. He clips Tim Bresnan over mid-on for four, before another boundary with a superb cover drive.

The Vikings really need to get one of this pair out soon.

No changes yet in the Yorkshire attack. They are relying heavily on Steven Patterson and Tim Bresnan with teenagers Karl Carver and Matthew Fisher both in the side.

After five tight deliveries from Patterson, Michael Klinger shows what he's about by comfortably hitting him back down the ground for four.

This is a very solid start for the visitors.

Chris Dent, after mis-hitting the first ball of the over from Tim Bresnan for a fortunate two runs, then hits a lovely cover drive to add three more.

From the final ball of the over, Dent punishes an overpitched one, smashing it for four down the ground.

And presumably the One-Day Cup side as well.

Michael Klinger is looking like a man in prime form as he hits Steven Patterson's first ball of the over straight over mid-on for four. He was so pleased with that he just watches it roll to the rope, rather than run.

The Australian strikes another boundary through the covers before getting two from a careless mis-field at mid-on from Alex Lees.

Michael Klinger is on the offensive, and he adds three runs off Tim Bresnan. But the England bowler goes after Chris Dent, who comes close again to nicking the ball behind.

Michael Klinger is having a sterling year in the One-Day Cup, and he brings up his 400th run from seven matches with a four off Steven Patterson. A solid start from Gloucestershire.

Huge appeal from Tim Bresnan's first ball of the day to Michael Klinger, but it just appears to be going over the bails. It's a tight rest of the over from Bresnan, with only a single conceded.

Incidentally, he might not playing in the game but Liam Plunkett is in the crowd supporting his Yorkshire team-mates, after his one-day appearance for England against Australia on Saturday.

Chris Dent almost feathers the second ball from Steven Patterson to the wicketkeeper, but the ball just missed the egde of the bat, and Dent composes himself to hit two runs to get off the mark.

Everything is set at Headingley and Gloucestershire are out to bat. Chris Dent will face Steven Patterson with the new ball.

For those of you just joining us, here's a recap of the Yorkshire innings.

Adam Lyth, who struggled fruitlessly against Australia in the Ashes this summer, hit a masterful 96 off 88 balls to get Yorkshire off to a flyer.

But after he fell the middle order struggled for runs, with only Gary Ballance, Jonny Bairstow and Tim Bresnan making any sort of meaningful contributions to leave Gloucestershire win 264 to win.

We also can't forget to mention Liam Norwell dropping an absolute dolly of a catch off Bairstow, seemingly celebrating a tad too early.

Gettable? We'll soon find out.

This isn't the first semi-final in which Yorkshire and Gloucestershire have faced each other. Back in 2004 they did so in the C&G Trophy at Bristol.

Yorkshire also batted first on that occasion, making 243-6 from 50 overs, thanks mainly to an unbeaten 80 by Australian Darren Lehmann, now coach of the Australia national team.

It was not good enough, however, as New Zealander Craig Spearman hammered 143 not out from 122 balls to see Gloucestershire home with 3.5 overs to spare. They went on to win the trophy at Lord's, beating Worcestershire by eight wickets at Lord's, their last piece of silverware. 

Of course, Gloucestershire have a New Zealander in their current side - will Hamish Marshall be the match-winner at Headingley?

But that's tomorrow, coming up we have the second half of today's match, with Gloucestershire looking to chase down a target of 264 and reach their first Lord's final since 2004. 

We will be back with you in time for the start of their reply to Yorkshire's 263-9, when Phil Shepka will be describing events at Headingley.

But injury has affected Nottinghamshire's plans for Monday's semi-final at The Oval...

Tomorrow it will be the turn of Surrey and Nottinghamshire at The Oval and we'll be bringing you full match coverage from about 11:15 BST.

Surrey have named their squad for the match, it is: Batty(capt), Ansari, Burke, Burns, S Curran,T Curran, Davies, Dernbach, Dunn, Foakes, Kapil, Sangakkara, Wilson.

So, 263-9 by Yorkshire - is that going to be enough? They'll certainly need to get rid of Gloucestershire skipper Michael Klinger early - he's scored almost 400 runs in the One-Day Cup this summer, with two hundreds and two half centuries.
