If I had a bingo ticket, and if I had getting out to a reverse sweep to deep point, I don't think I'd ever get house.
WICKET
Naveen c Chapman b Santner 0 (Afg 139-9)
Start the car.
New batter Naveen attempts to reverse-sweep his first ball from Mitchell Santner but can only top-edge to Mark Chapman running around from point.

His front foot was almost off the wicket to the left of him. New Zealand had a good field set with a fine leg.
WICKET
Mujeeb c Young b Ferguson (Afg 138-8)
Mujeeb Ur Rahman hits a four off his first ball, a dot off his second and is out off his third.
It is short and very fast from Lockie Ferguson, luring Mujeeb into the pull. He cannot get on top of it though so can only pick out Will Young on the fine leg boundary.

Rashid Khan was trying to work out how to face Lockie Ferguson, apart from trying to not face him. Ferguson bowled a middle and leg line and it meant Khan had to come back towards that leg side. It tucked him up, so by the time he came to play it down the ground he had an open face bat and it was an easy catch for Daryl Mitchell.
WICKET
Rashid c Mitchell b Ferguson 8 (Afg 134-7)
Rashid Khan goes after Lockie Ferguson, but loses his wicket as the ball skews off a leading edge into the sky and is well taken in the covers by Daryl Mitchell.

Here is how Rahmat Shah fell earlier, with Rachin Ravindra claiming a caught and bowled chance after a lengthy check by the third umpire.
Afg 133-6
Shot.
After a few balls fending off Lockie Ferguson, Rashid Khan takes advantage of the relative freedom afforded by Mitchel Santner and clatters the ball back over his head for six.
Afg 126-6
Rashid Khan is the new batter and he is immediately in the thick of it as Lockie Ferguson bowls an aggressive line from around the wicket, with the ball leaping up off the surface and cramping Rashid for room.
Another maiden from Ferguson means he is 1-15 from his six overs so far.
WICKET
Nabi b Santner 7 (Afg 125-6)
It's not so flat any more. That's a beauty from Mitchell Santner.
Classic left-armer's delivery as it pitches on middle and leg, turns and clips the top of off stump.
It is Santner's 100th one-day international wicket and makes him the joint top wicket-taker in the competition.

Thanks, Mike.
Where do Afghanistan go from here? It is all a bit flat at the moment.
Afg 121-5
Back comes Lockie Ferguson - he had figures of 1-8 from four overs in his first spell.
He's slightly less economical this time around, as Ikram takes two down to mid on before edging for four.
Here's Tom Mallows to take you through to the conclusion.

Afghanistan need to get on with it. They need 8.5 an over.
I'd much rather see them play a few shots, get out and help their net run rate that way, than sit in and see out their overs.
Afg 114-5
Target 289
Ravindra drifts one down leg and Ikram swat-sweeps him to the backward square boundary for four.
WICKET
Rahmat c&b Ravindra 36 (Afg 107-5)
Yes, that's gone - after lots of rocking and rolling of the camera frames, the third umpire decides the ball came cleanly off the bat.
In comes Mohamed Nabi, with 150 ODIs to his name. He averages 26.78 from those, but he'd need a fair few more today if Afghanistan are going to stand any chance of winning.

The side on angle looks quite conclusive. I think that's out.

It was all very, very casual out there.
Umpire review
Possibility of a caught and bowled chance for Rachin Ravindra - does he have the wicket of Rahmat?
It struck very low on the bat - the umpires are taking a look to see if it's a bump ball.
