Rashid Khan’s here to have some fun it seems.
Australia’s preference to keep banging the ball in short hasn’t been without its success today, but at times it has seemed a little bit premeditated.
Plenty for Aaron Finch and co to ponder as the tournament goes on.

Daniel Davies: If Afghanistan aren't your favourite team at the Cricket World Cup, then you're lying.
Simon Mann
TMS commentator
That flew into the crowd! It was a magnificent blow.
More runs for Rashid Khan!
First he squeezes one beyond midwicket for four. Then, next up, he sends a straight-batted slap beyond mid-off for another boundary.
Then, to complete the over, he sends a pull over midwicket for six!
21 from the over!
Afghanistan aren't going down quietly.
Rashid Khan strides forward and dispatches Marcus Stoinis back over his head for six.
Lovely shot.
Dawlat Zadran c Carey b Cummins 4 (Afg 166-8)
That was coming. Some more short stuff from Cummins, Dawlat Zadran tries to pull but can only glove the ball through to Carey.
It's all happening now.
Some oohs and ahhs from Pat Cummins has he dangles the ball just outside off stump. Dawlat Zadran has a swing but doesn't make contact.
Cummins then bangs in one short and Dawlat has no idea where that is, but somehow his no-look pull disappears down to fine leg for four.
Dawlat Zadran is the new batsman. Can Afghanistan last the distance?

Afghanistan are now in danger of not seeing out their innings.

Najibullah Zadran has done exactly what Gulbadin Naib did there. It is another wasted opportunity.
Najibullah Zadran c Carey b Stoinis 51 (Afg 162-7)
Two in the over! Another short ball is skied into the air and Carey takes a simple catch!
Marcus Stoinis comes in... and it should be another wicket! A top edge from new batsman Rashid Khan lands between square leg and fine leg!

That was a decent knock but like Rahmat Shah earlier he needed to find a way to just go on.
Gulbadin Naib c Carey b Stoinis 31 (Afg 160-6)
Oh dear. After playing so well Gulbadin Naib looks to pull a short one from off to on, but only succeeds in top-edging it into the sky and Alex Carey takes the catch.
Mitchell Starc is nudging 90 mph but Afghanistan somehow deal with it. The final ball is banged in short and Najibullah pulls. sending a top edge over the wicketkeeper for four to bring up his fifty.
Well played sir.

This is the highest six-wicket partnership against Australia in World Cup cricket since 2003.
Geoff Lemon
BBC Test Match Special commentator
That has gone a long way back.
Afghanistan are starting to up that run-rate now. It's coming together.
Afghanistan are battling hard.
Najibullah Zadran sends a Nathan Coulter-Nile delivery back whence it came for another big six over long-on.
Graeme Swann
Ex-England spinner on BBC Test Match Special
This is good from Afghanistan. It's going to make more of a game of it.

Gulbadin Naib is basically fielding at mid-on with Adam Zampa at the moment.
He doesn't want the strike with Mitchell Starc bowling.
