Is Gulbadin Naib run out?
That's another brilliant throw and direct hit from Glenn Maxwell.
It has gone upstairs. But the way Australia are celebrating suggests this is out.

Is Gulbadin Naib run out?
That's another brilliant throw and direct hit from Glenn Maxwell.
It has gone upstairs. But the way Australia are celebrating suggests this is out.
That is a decent over in the end from Pat Cummins, just the one run from it.
There's a few nervous expressions on the Australia players though. This is not going to plan.
Ooh, so close to a brilliant catch from Glenn Maxwell.
It is airborne from Gulbadin Naib. Maxwell is running in from long-on to claim, but the ball is dying on him so he ends up taking the ball on the bounce.
He could not have done much more there.

Afghanistan can legitimately start thinking about getting a famous victory here.
And another! Ibrahim Zadran has smashed it through the covers for a one-bounce four.
17 runs from Kane Richardson's over.
This is bubbling up to a thrilling finish here.

A wonderful effort out there in the deep by Steve Smith but he just couldn't get there in time. Unlucky!
Gulbadin Naib has absolutely creamed that.The ball has flown towards deep mid-wicket and beyond the despairing dive of Steve Smith, who tumbles over the rope.
The next ball fizzes off the edge and away fine for four. Afghanistan re getting going!
Afghanistan were wobbling a bit at 40-2 but Ibrahim Zadran and Gulbadin Naib have steadied the ship, with seven coming from that Adam Zampa over.
90 needed from 54 balls.

There's good reason for Afghanistan to beat Australia because if they finish in the top four they qualify automatically for the next World Cup.
The BBC TMS team have been crunching the numbers and they think that if Afghanistan reach 119 Australia will not be able to better England's net run-rate, which means they will definitely progress with a victory over Sri Lanka on Saturday.
That is easier said than done, of course.
Australia may be ahead in the run rate, but Afghanistan are scoring well and it looks unlikely that Australia will be able to restrict them enough to affect England too much.
Although, it's still a must-win match for England.
Target 169
Oh dear, Adam Zampa.
Ibrahim Zadran cuts the ball away towards third man and Zampa fumbles the ball on the boundary and it trundles over the rope.
A single off the final ball moves Afghanistan to 72-2 at the half way stage.
He did. He was well home to be fair.
Ooh, a bit of confusion between the Afghanistan batters as they consider a single.
The throw is a direct hit as Ibrahim Zadran dives into his crease. Did he make it in time?
The third umpire is going to have a look.

What a shot that is from Gulbadin! That's come out of almost nowhere.
Absolutely nailed!
Gulbadin Naib has just mullered Cameron Green over mid-wicket for six. That's a massive hit.
That's a good response from Adam Zampa. After going for eight from his first three balls he concedes just one from the next three.
Australia are managing these middle overs well.
That's a lovely shot from Gulbadin Naib.
He was offered a bit of width by Adam Zampa and Gulbadin has slapped the ball through extra cover for four.
Cameron Green is the new bowler - Australia do have plenty of options with the ball this evening.
It is a good over as well. Green repeatedly beating the outside edge of Ibrahim Zadran's bat.
Just the one run off the over. Four off the last two. Australia cranking up the pressure.

Economical over by Zampa.
But how do Australia juggle their bowlers and how do they attack?
