Afg 91-5published at 24 overs
Another bouncer (obviously!) ends the over.
Gulbadin Naib plays it much better than his colleague did the previous ball.
Afg 91-5published at 23.5 overs
That's a snorter from Pat Cummins!
This over has been much much better from the Aussie quick and his latest short-pitched delivery raps Najibullah Zadran on the glove and flies down towards third man.
Najibullah didn't play that particularly well at all.

End of twitter postAfg 90-5published at 23 overs
There's a run-out opportunity off the final ball of the over as there's more confusion between Gulbadin Naib and Najibullah Zadran.
Thankfully for Afghanistan, Aaron Finch's throw misses and the non-striker gets home.

Vic Marks
Ex-England spinner on Test Match SpecialThe shots are getting better. It was over-pitched by Stoinis but beautifully timed by Gulbadin.
Afg 90-5published at 22.3 overs
Gulbadin Naib has raced to 14 off 11 balls after picking up his third boundary with a lovely flick through the on-side for four.
There were shouts of catch but Usman Khawaja had no chance at short mid-wicket.

Zampa's 20 ODI wickets in 2019 is the joint most of any spinner (Kuldeep Yadav also 20).

Luca: Four games into the World Cup and there hasn't been a competitive game yet. Remind me again why the likes of Scotland, Ireland et al were squeezed out?
Afg 86-5published at 22 overs
Nine runs from the over - a very profitable one from Afghanistan.
Afg 85-5published at 21.4 overs
Much better, Pat Cummins!
An improved length draws a false shot from Gulbadin and has Alex Carey oohing and ahhing behind the stumps.
Afg 85-5published at 21.3 overs
And again!
Short again and Gulbadin again finds the leg side boundary.
Odd bowling with a slip in place.
Afg 81-5published at 21.1 overs
That's a loosener from Pat Cummins!
Gulbadin gives it the treatment is deserves and it races to the cow corner boundary.

Pat Cummins replaces Adam Zampa for Australia.
Aaron Finch really is mixing his bowlers up...

A maiden for Marcus Stoinis - with the wicket coming from a run-out.

Gulbadin Naib was not moving at the non-strikers' end there!

BBC Test Match Special commentatorAfghanistan have burned one of their best batsmen there, and certainly one of their best strikers of a ball. A dramatic waste.
WICKETpublished at 20.2 overs
Nabi run out (Smith) 7 (Afg 77-5)
That is brilliant from Steve Smith!
You just can't keep him out of the action.
Mohammad Nabi creams a back-foot drive and Smith sprawls to his left to stop it brilliantly. He jumps to his feet, composes himself, and throws it to Alex Carey who takes care of the rest.
Nabi was still half way down the pitch.

Adam Zampa hasn't even bowled that well so far but has two wickets.
Encouraging signs for Australia.
