James Pattinson, after being beaten all ends up by Jade Dernbach, runs hard for another two and takes Notts a single blow from One-Day Cup glory. Six needed.

James Pattinson plays a nice-looking stroke through the covers first up for a couple of runs.

The chase is now down into double figures for Notts - nine needed from 24 balls.

Alex Hales has just played a couple of weary-looking shots in that last Jade Dernbach over, which goes for five.

The double century surely is no longer on. But will he care? I wouldn't have thought so, providing he has his hands on that trophy in half an hour or so.

44 overs

Hales 184, Read 50

Fantastic. Chris Read, retiring at the end of this season, reaches 50 in what will surely be a Notts winning cause. Fairytale stuff.

He reaches the milestone in slightly weird fashion, ducking a bouncer but seeing the ball cannon off his vertical bat.

These two are seeing it home.

You wonder now, too, whether Alex Hales may just begin to free his arms once more to make sure Chris Read doesn't scupper his double century hopes.

A couple of sharp twos helps his cause, and a single from the final ball keeps him the strike.

Notts need 26 from 42. Coasting.

Ravi Rampaul's race is run, his 10 overs going for 2-52. Just the three from that last set.

Just 33 more runs from 48 balls needed for Nottinghamshire.

Alex Hales is showing no signs of fatigue, no heavy breathing or panting. He's hardly even sweating.

Surrey are looking a little bit despondent, they've got to maybe try to get the ball reverse-swinging and keep the ball dry.

Gareth Batty has kept things ridiculously tight today, going for just 34 runs from his eight overs so far.

The issue for him is that Alex Hales has been sublime against the quicks. Is a double century still just about in sight?

MB: I know one knock doesn't get you a test place but certainly another look from the ECB at Alex Hales to open the batting.

Taha Hashim: Hales on for the double ton here. Sublime batting.

Glenn Inniss: Hales batting Surrey into submission. As a good a one-day innings as we're ever likely to see.

Daniel Stevanato: Hales has nearly 72% of Notts' runs today. What's the record for individual percentage of runs in a completed List A innings?

IRD: Alex Hales' back must be absoluty killing him.

A streaky inside edge for four moves Alex Hales onto 171, which is the new highest-ever List A score at Lord's, beating David Boon's 166 for Australia against the MCC in 1989. The records are tumbling!

Hales has also equalled his personal-best List A score. And, all the while, this partnership is now worth 107 too.

Notts, from here, are surely well on their way.

A handy over from Surrey captain Gareth Batty, limiting the damage to just two runs.

Notts need 51 from 66 balls. Surrey need five wickets.

Surrey have come at Notts all day with the same thing - 80mph good-length balls - and Alex Hales has been quite happy to hit those away at will and they haven't really had a plan B.

Alex Hales is closing in on another Lord's record now - we'll cover that one if and when it happens - but it looks like Chris Read might spoil his double century party.

The Notts wicketkeeper/batsman has 38 from 39 balls, including another four from that latest Ravi Rampaul over.

Now Chris Read's getting in on the act too, pulling Tom Curran for four. Surrey are becoming frustrated here, but still a wicket could open this final right up. Make no mistake about that.

See the moment that Alex Hales broke the record for the highest-ever individual score in a county final at Lord's...

Duncan Mitchell: Ollie Pope could well have handed Notts the trophy today. Dropped Hales on 9....

Josh Verrills: Can always rely on Surrey to bottle it in the final every year after playing so well to get there

Nigel Goodwin: So can I ask why hales is not considered for a test place?

I did pose the question earlier, Nigel! But also, in part, answered it.

It's one thing flashing the blade in this format - and, don't get me wrong, he's been fabulous today - but he'll need to prove he's ironed out his weakness outside off stump with the red ball.

Jade Dernbach's into the attack, but a clip behind square for four from his second delivery moves Alex Hales onto 163.

It's 70 to win from 83 balls for Notts. Surrey badly need a wicket, obviously.

Tom Curran's back and he's again proving a little expensive, this over going for seven - including an 18th four for Alex Hales. He's only 15 short of his best-ever List A score now.

His partnership with Chris Read, which I was talking about a moment ago, is unbroken on 70.

Alex Hales just goes on, and on, and on. But more importantly than that, he now has a partner willing to stick around with him for a bit.

Chris Read's unbeaten 24 has been really important in just ensuring Notts are well in contention because, when he came to the crease, they were arguably looking up against it.
