That's an absolute beauty from Steven Patterson. The paceman, from around the wicket, gets one to lift and bounce just past the edge of Nick Gubbins.
He was so, so close to finding a nick. Gubbins survives.

Somerset beat Notts by 325 runs
For the time being Somerset are the Division One leaders. However, Yorkshire will earn another 16 points if they beat Middlesex taking them to 227 and one clear.

It's an absolute thumping by 325 runs. Somerset go top of Division One - but only a draw at Lord's will see them become county champions.

Middlesex 270 & 30-2 v Yorkshire 390
Nick Gubbins is a lucky lad. He tries to flick Tim Bresnan through the leg side but gets a leading edge down to the third-man boundary.
He's up to 19, Middlesex are just chipping away at this lead. They're 90 behind.
Hampshire 411 & 113-6 v Durham 361

Hampshire's lead is 163.
Middlesex 270 & 26-2 v Yorkshire 390
Middlesex's Dawid Malan also owes his county some runs after his first-innings duck. He's already played one lovely drive off Jack Brooks.
Middlesex 270 & 22-2 v Yorkshire 390
Nick Gubbins has been the only Middlesex batsman to show any real resistance in this match, and the 22-year-old is showing plenty of guts once again.

Somerset need two more with 40 minutes left on day three.
Hampshire 411 & 108-5 v Durham 361
That's a big blow for Hampshire's survival hopes. Sean Ervine, who is in the form of his life with the bat, is caught by Mark Stoneman in the covers off Ryan Pringle.
Hampshire, who need to win unless Lancashire chase down an unlikely 347 at Edgbaston, only lead by 158.
And Lancashire have just lost a wicket. Rob Jones goes lbw to Keith Barker and the visitors are 4-1.
Somerset 365 & 313-5 dec v Notts 138 & 182-7
Nottinghamshire may be heading for defeat but the one bright spot is a maiden Championship fifty for Billy Root, younger brother of Joe.
The 24-year-old hasn't hung around either, reaching his half-century off 56 balls.
Notts still trail by too many to matter though.

Peter Carr: Poor Somerset, the title race could be all but over by tonight
Middlesex 270 & 2-2 v Yorkshire 390
That is an absolute peach from Jack Brooks. The paceman gets one to just nip away from Nick Compton who is beaten all ends up.
Yorkshire are now huge favourites to lift their third County Championship title in a row.
Somerset 365 & 313-5 dec v Notts 138 & 149-7
Nottinghamshire's innings is collapsing. Chris Read goes lbw to Jack Leach before Brett Hutton is bowled by the Somerset spinner two balls later.
Notts are seven down.
And there's been another wicket at Lord's....
Middlesex 270 & 2-1 v Yorkshire 390
The ball is doing all sorts out there. Every Ryan Sidebottom delivery looks threatening.
It's been an extraordinary, hearts in the mouths sort of day at Lord's - but we wouldn't have wanted it any other way.
