If you bowl straight at him he's OK.
It's when he's got to move that he struggles!

He really is a very average wicketkeeper Mohammad Shahzad, I'm afraid.
He was about a week and a half late on that.
More sloppy play from wicketkeeper Mohammad Shahzad as he lets another one slip through for five wides.
An attempted slower-ball sits up nicely but David Warner perhaps tried to hit it too hard, he skies it and Australia run two.
Gulbadin Naib oversteps for a no-ball to end the over. That will be a free hit.
Next up is a wide, so ANOTHER free hit....
Lovely shot from David Warner. Gulbadin Naib looks to cramp him for room but Warner plays a delicate cut down to third man for four.
Khawaja is the leading ODI run scorer in 2019 - hitting 769 runs at an average of 59 from 14 knocks so far this year.
Mohammad Nabi comes into the attack.
Usman Khawaja is able to nudge a quick single to get off the mark. Nabi then fires one very wide, Mohammad Shahzad cannot get there and the ball disappears for five wides. Sloppy again from Afghanistan.
Eight from the over.
Thanks Callum.
All fairly comfortable for Australia so far. Afghanistan need wickets and fast.
Tom Mallows is going to take you through to the close of play.
That's poor from Afghanistan.
David Warner works it off hips and Hazratullah Zazai down at fine leg completely misses the ball.
Gulbadin Naib has pain etched all over his face.
Gulbadin Naib will get us going after the break.
He might be back in the shed now, but here's how Aaron Finch brought up his half-century.
It's time for a drink. Or a hydration break, if you're the ICC.

That's the adaptability of David Warner, going for finesse rather than power.
That's a lovely bit of timing from David Warner.
Rashid Khan is straight but Warner carves it down to the third man boundary.
He played that so late it was almost in Mohammad Shahzad's gloves!
If that was the first take Jim, I'm impressed!

Usman Khawaja is the new batsman.
The batsmen crossed so David Warner safely negotiates the rest of the over.
Australia need another 110 to win.

Ex-Australia batter on BBC Test Match Special
A fantastic start to the World Cup for Aaron Finch. He played with intent, particularly against the spinners, right from ball one and he has set Australia up beautifully.
