You'd swear that there's nobody here now. Every time there's a boundary from Nottinghamshire, the crowd fall silent.
These are just good cricket shots from Notts, nothing more than that. You have to sit back and admire that.
Hales 29, Wessels 9
Image source, Rex FeaturesBOSH! Riki Wessels carts Neil Wagner over cover and it races to the boundary.
Alex Hales is also motoring - he flays the New Zealander through the covers and is up to 29 off 13 balls.

Alex Hales looks like he's taken to being back in Notts colours like a duck to water, Jake Ball less so.
But they're both county-contracted players and if they're asked to play, they will play despite the disappointment they felt earlier this week with England.
Hales 22, Wessels 4
Cheeky. So, so cheeky from Riki Wessels.
The Notts batsman gets down on one knee and scoops Jamie Porter to the boundary behind square.
Alex Hales also found the rope in that over with a clip through mid-wicket. It's such a good batting wicket - 370 might not be enough.
Hales 17, Wessels 0
Yep, television replays suggest Alex Hales hit the ground rather than nicking behind.
Fast start for Notts, but Essex have grabbed that all-important wicket of Michael Lumb already.
Notts 26-1
Howzaaaat? Not out. Neil Wagner screams at the umpire thinking Alex Hales has nicked him behind, but he shakes his head.
Bat on ground maybe?
Hales 10, Wessels 0
Riki Wessels is the new man in and sees out Jamie Porter's final ball of the over.
Notts 21-1
Early breakthrough for Essex!
After a couple of boundaries past slip and through the covers, Michael Lumb tries to flick Jamie Porter past square leg but spoons up a catch to Simon Harmer at point.
Big wicket for the hosts.
Lumb 3, Hales 9
Halesy is away immediately. Short from Neil Wagner, slapped over mid-wicket for four.
Next ball, the England opener places it through the covers to the boundary.
12 off the first over. They've just got to keep that up for another 294 deliveries now!
Lumb 2, Hales 0
Image source, Rex FeaturesHere we go. Neil Wagner opens things up for Essex and Michael Lumb is off the mark with a punch through square for two.
Essex 370-5 (50 overs) v Notts
Thanks Adam.
Well, what a chase we've got on our hands with a certain Alex Hales set to open for Notts.
Don't forget, Nottinghamshire scored 429 a few days ago to beat Somerset - but they've got the old 'scoreboard pressure' to deal with this time around.
The players will be back out shortly...
Essex 370-5 (50 overs) v Notts
So, not long now until the second innings of this game gets started.
371 is the victory target for Nottinghamshire to get to Lord's, where they last appeared in a domestic final in 2013.
Essex haven't been back to the Home of Cricket since 2008, so they'll be keen to do all they can to get there.
Gary Smee will take you through the start of the Nottinghamshire reply shortly....
So, where does that 370-5 rank on the all-time list for Essex? Fourth is the answer. And the second best against a first-class county.
Here's the top five...

Ryan ten Doeschate lit-up the closing overs of that Essex innings with a flurry of boundaries in his 64-ball century.
He here is taking the applause of the Chelmsford crowd as he walks off.
