In their semi-final, Nottinghamshire chased down a target of 371 to beat Essex, with Samit Patel and Steven Mullaney both hitting hundreds.

Scoring 298 to beat Surrey should be easy then....but I very much doubt that will prove to be the case.

Yes, Notts have a powerful batting line-up, with five of their top six having made at least one century in this year's competition, but if Surrey can get in among them with two or three early wickets, this could well turn out to be a close contest.

Although he probably wouldn't want to be classed as a white-ball specialist, Notts opener Alex Hales has developed into a highly effective 'dasher' at the top of the order in 50-over cricket.

His 104 off 103 balls against Durham in May was a reminder of exactly what what he is capable of, and although England commitments have restricted him to six appearances in this season's One-Day Cup, his strike-rate of 101.64 underlines his importance as they prepare to chase a target of 298 to win at Lord's.

Sam Curran and Jade Dernbach may not be the quickest new-ball pair around, but they have shared 31 wickets between them in the competition in 2017 and Curran's swing and Dernbach's variations could be crucial if Surrey are to come out on top.

Curran is still only 19, and a 'baby-faced assassin' to use Hollywood parlance, and it will be no surprise if he follows elder brother Tom into international cricket in the near future.

So, Notts need 298 to win their first List A trophy for four years, and their first in 50-over cricket since 1989. The Outlaws have a powerful batting line-up, but a score of that size certainly won't be a cakewalk against Surrey's talented attack.

And with that, it's time for us to take a munch break for a few minutes, but we'll be back with you for the start of the run-chase when Paul Grunill will be back in the text commentary chair.

Some excellent cricket this morning at Lord's, but the England and Wales Cricket Board won't be happy about the number of empty seats in the ground, having brought the final forwards from September to July as part of a restructure of the season.

Why have people stayed away? What time of the season do you think would be best to stage the final? Should future finals be made day-night in the hope to attracting late arrivals?

Let us know what you think.

If you're not at Lord's this afternoon, here's what you are missing food-wise. Tasty!

For Nottinghamshire, it was all about the middle overs bowled by Samit Patel (3-51) and Steven Mullaney (2-50).

With Jason Roy and Kumar Sangakkara already in the hut, Scott Borthwick, Ben Foakes and Ollie Pope all fell in quick succession to leave Surrey behind the eight ball.

The other major plus - as much for England as Nottinghamshire - was that seamer Stuart Broad survived nine overs unscathed, although his figures of 0-51 weren't necessarily anything to write home about.

That Surrey innings was all about one man - Mark Stoneman.

He struck 12 fours in his 149-ball 144 not out, his personal best score in List A cricket and a knock that gives his side a fighting chance.

No other batsman made more than 30, with Jason Roy, Kumar Sangakkara and Sam Curran all getting starts but failing to make hay.

Surrey have had opportunities to get a very big total but, that said, they've still got basically 300 runs on the board so that's going to take some chasing.

With this being a final it's a par score - but you would be happy chasing that.

Luke Fletcher was quite expensive in the five overs he bowled this afternoon but he did manage to get a little bit of joy by taking Gareth Batty's wicket

You can watch that below...

It's hard to say who'll be the happier with that total at the halfway stage.

After winning the toss, Surrey got off to exactly the sort of flier they would've wanted inside the first 10 overs. But then Notts put the brakes on in the middle third with tighter bowling and regular wickets.

It could've gone even better for them had they held on to their chances in the field early on, especially that catch to first slip offered by Jason Roy to Riki Wessels off the very first ball.

Mark Stoneman finishes two runs short of the highest individual score in a Lord's final, but you have to applaud his application for being there throughout the 50 overs.

Notts will back themselves to chase this, but Surrey will believe they have the bowlers to defend it. Should be finely balanced.

But Mark Stoneman can't connect, settles for a leg bye and falls short of the biggest-ever individual total in a county final at Lord's.

The man who holds that record? BBC Test Match Special's very own Geoff Boycott, of course. His 146 not out - against Surrey - keeps the record.

Nottinghamshire will require 298 to win the One-Day Cup.

This time Jade Dernbach goes down the ground, but again he takes a couple. Mark Stoneman can't get a look in!

Jade Dernbach guides the ball to fine leg - they take two! Dernbach will keep the strike .

Jade Dernbach attempts to blast this out of the ground, but can only hit fresh air.

But that one really hasn't gone to plan for Harry Gurney, who sends down five wides, attempting to follow Mark Stoneman across the crease. I'm not sure that even landed on the strip.

Harry Gurney leads an appeal for leg before against Mark Stoneman, but the umpire is unmoved. Stoneman takes a single.

Nicely done by Luke Fletcher, that. Only five runs come from the penultimate over, as he twice threatens the toes of new man Jade Dernbach.

Mark Stoneman takes a single off the last delivery, though, meaning he keeps a strike and is still homing in on the biggest-ever individual total in a county final at Lord's. More on that in a moment.

Harry Gurney will bowl the final over...

Before we do tuck into the closing stages though, I reckon that run out of Tom Curran a little earlier on is well worth a quick look...
