Derby, the Racecourse Ground, is the windiest place to play, especially early season. You can lean into it and end up at about 45 degrees.

Width from Ball, and Guptill lashes it through the covers for a boundary. New Zealand have had enough of this prodding around, letting England bowl at them. Ooft, that's glorious from Williamson. A straight drive, just the tiniest shuffle forward and nudge of the bat, and Moeen gives up the chase as the ball races down to the rope. Nine from that over.

Williamson picks up his first boundary with a flick off the pads that races past Alex Hales. These two might be starting to find a bit more of a groove now, working the singles and playing with the bounce.

David Hoy: Don't know why TMS & reporters are moaning about weather at Cardiff, it's been heavy rain all day here in Edinburgh

Four! The first boundary of the New Zealand innings goes to Guptill as he cracks a straight drive past Ball. Ooh and another, Guptill slicing a wide ball beyond a leaping Jason Roy and into the ropes. This is Ball's most expensive over, which doesn't please him, and he ends it with a vicious delivery that cuts Guptill in half.

Mike Bell: Interesting that Aggers mentions old 'Sunday League run-up'. Maximum eight paces, with two hours ten minutes to bowl 40 overs!

A groundsman has appeared with a mallet, which he uses to knock the stumps a bit further into the ground. Guptill drives and then flaps his right hand as the ball ricochets off the bottom of the bat. Wood rounds off another excellent over for England with a nice length delivery that Williamson can't resist a little fiddle at.

This is grim for everybody. It's a day for the heavy bails. There's some trees at one end which look like they're about to snap and fall into the River Taff.

The bails are flashing away on the ground, but it's the wind that's dislodged them, rather than the bowler. It can't be easy for Jake Ball, having to charge into that wind and keep his shape and his rhythm, but it's been an admirable performance so far. Williamson gets a single off the last ball, driving with the feet of the ground, as Morgan mis-fields slightly.

Tone: Wickets, wickets, wickets. Early wickets required to get ahead of D/L.

Ah, Kane Williamson. Up on his toes and driving, elbow high, away for three runs. It is really, horribly windy out there. The bails have already come off once and I've no idea how Bruce Oxenford has kept his floppy hat on his head. That's a belter from Wood, 89mph and straight through Williamson's shovel forward, the batsman glued on the back foot.

This is a middling sort of score and sets up a good game. If either side plays particularly well with the bat or ball, they'll win.

A good over from Ball, only conceding a bye. He's found his rhythm; full, straight and keeping Guptill on the defensive. Here is that dismissal of Luke Ronchi, gone for a golden duck.

Ah, the British sporting summer. Sunshine, simultaneous black clouds, permanent anorak...

Here's Mark Wood, getting Williamson onto the back foot. Wood's found that bit of extra bounce and Williamson can't resist a little flirt at a tempter outside off stump. The crowd ooh's and Williamson readjusts, getting his first run with a little tap into the covers.

I think the wind has got stronger all of a sudden. Ball keeps checking his run-up, he can't just get there. In the olden days, he'd just adopt his Sunday league run-up in this circumstance.

Ronchi looked in good touch against Australia. To get him with the first ball he's faced in Cardiff is excellent for England. That brings Kane Williamson to the crease. Get him early and, well...

Ball pulls out of his delivery stride twice as the wind lashes across the ground, and gets a huge round of applause as he bowls the last ball of the over.

That was straight, relatively quick and it skidded on. Ronchi was not quite acclimatised. He's a wildcard at the top of the order. He's out there to play his shots but he won't be playing anymore today.

Thanks to those of you who pointed out that it is indeed June, not July... it feels like February. Jake Ball which take the new ball, while I check my calendar.
