Notts reach 298-6 with 13 balls to spare to win the trophy
Hales (187*) makes highest score in a Lord's final
The England opener was dropped on nine
Surrey made 297-9 after skipper Batty opted to bat first
Stoneman hits 144* after missing out on Test selection
Mark Stoneman may only have struck 12 boundaries in his 140, but his running between the wickets has been absolutely immense, typified by a brilliant two at the start of that latest over
His score here is also his best-ever in List A cricket, passing his previous best of 136 not out against Scotland for Durham in 2012.
Twelve to go...
Surrey 279-7
And it most certainly did bounce first, so Gareth Batty remains. In fairness to Chris Read, there was no real appeal, more an asking of the question to check.
On we go...
Surrey 279-7
Now then, has Gareth Batty nicked the ball behind? Chris Read takes the catch, but we're having a look to see if it bounced first...

Stoneman 136, Batty 10
Interestingly, both batsmen actually show a little more adventure facing England quick Stuart Broad, who sees a loose delivery chopped away for four - although substitute fielder Billy Root is guilty of a poor error on the rope.
Harry Gurney replaces Luke Fletcher, 18 balls to go...

Nottinghamshire have really stuck at it today because I get a feeling that this is a good wicket especially for facing the quicker bowlers.
Luke Fletcher is back for a little bowl then, very much your classic county seamer doing the hard yards for his team.
What surprises me here is almost the lack of ambition from Gareth Batty and Mark Stoneman, wandering through for the singles Notts will be more than happy to limit them to.
Six come from that over.

They were running so well all day but that was almost one too many. Tom Curran felt he couldn't get back and was left stranded and sacrificed himself and rightly so, doing the right thing for his side.
A shame for Surrey, that partnership was big in getting up to 300 or 310.
Surrey skipper Gareth Batty joins Mark Stoneman in the middle and immediately gets a healthy dose of good fortune from his second ball, edging Stuart Broad past Chris Read for four. Fortunate.
Five overs to go. Luke Fletcher is on.

Every cricket fan loves to see a fast bowler beating a batsman all ends up with a quick delivery that clatters into the stumps.
You can watch James Pattinson doing exactly that to Sam Curran below...
Surrey 255-7
Oh Tom Curran, what've you done here?
The recently-capped England T20 international clips Stuart Broad away and runs a speedy single but, despite Mark Stoneman's calls for a second, is hesitant and both batsmen end up at the bowler's end.
Curran, however, had strayed from his ground and so he's the man to go - which is probably just as well for Surrey, who still have Mark Stoneman unbeaten on 126.
Well bowled, Samit Patel. After two leaky overs in succession he limits his final set to just five runs for figures of 3-51.
Now then, how are we sharing the remaining six overs? Stuart Broad has three to bowl, while Harry Gurney, Luke Fletcher and Steven Mullaney are all options from the other end.

Pattinson finishes with figures of 1-48.

Nice bit of bowling there from James Pattinson, coming round the wicket, good pace, angling into the stumps.
It was poor footwork from young Sam Curran who's inexperienced at this stage.
Mighty talented, but no footwork there was his undoing.
That's a good over for Surrey having just lost Sam Curran, 10 coming from it, the final four of which were courtesy of a nicely-guided cut down to third man from Mark Stoneman.
James Pattinson is on for his final set.
The very impressive Mark Stoneman has been the glue that's held this Surrey innings together.
He's had a bit of luck along the way and he got some here as he brought up his century...

Nottinghamshire have had some good overs in the middle overs, taking those crucial wickets, stemming the flow of runs and wrestling back that initiative.
Image source, Rex FeaturesJames Pattinson is really steaming in here, twice beating the outside edge of Tom Curran without reward. Of the Nottinghamshire quicks, he's looked the pick I'd say.
Is Mark Stoneman in danger of running out of partners?
Big Samit Patel's on his way back...

Surrey 228-6
Got him!
Sam Curran is done for pace - all 87mph or so of it - by Australia's James Pattinson, who clatters his timbers and breaks what was looking a crucial partnership for Surrey.
Curran and Mark Stoneman, still going on 115, had shared 48 for the sixth wicket.
Out goes Sam Curran, in comes brother Tom.
Image source, Rex FeaturesStuart Broad lets out a cry of "NO!" as another tight delivery is worked away for a single. For as tidily as he's bowled, 11 runs have now come from his last two overs. Ever the competitor, he's cutting a frustrated figure at Lord's.
Ten more overs to come.
