Australia are now ahead on Duckworth-Lewis-Stern after that wicket but Pakistan are only nine runs behind.

Australia are looking to build the pressure on Pakistan now. They've got a slip and a gully and four other fielders in the ring.

Oh and it almost pays dividends as a flashing drive by Sarfaraz catches the edge and flies just past gully and away for a single.

Captain Sarfaraz Ahmed is the new batsman and he gets off the mark, first ball, with an inside edge down to the fine leg.

You always feel unlucky caught down the leg side but it happens so often I think pace bowlers are starting to take credit for it. Do they really aim for it? Perhaps it's not the worst ploy.

That is a bonus wicket for Australia.

This is Imam-ul-Haq's 12th score of 50 or more in ODIs, six of which are hundreds.

Even his trousers came off, which shows you how wholehearted he was in stopping that ball.

50 for Imam-ul-Haqpublished at 25 overs

25 overs

Pak 135-2

Oooh, Nathan Coulter-Nile extracts a genuine outside edge from Mohammad Hafeez but it flies past the slip cordon and a magnificent bit of fielding by Pat Cummins restricts him to two.

Imam-ul-Haq again tries to cut a ball that's too straight.

That's better! He gives himself a bit of room and lofts over mid-off for his seventh boundary and half-century.

Half way point and Pakistan need 172 more to win.

That's a cracking over from Pat Cummins. He beats Imam's outside edge with two snorters - the second one leaves the left-hander on his knees. He tried to play a cut shot and it was never wide enough to be cut.

A glorious straight drive from the final ball is well stopped by Cummins.

Pat Cummins - who has figures of 1-18 from four overs - is going to replace Mitchell Starc.

David Warner has strolled off the field. Maybe he's putting his bowling boots on? It'll be interesting to see the reaction of the crowd if that happens.

Tidy from Nathan Coulter-Nile but non-threatening as five runs are added to the total.

At the end of the 21st over, Pakistan were one run behind the DLS par score. A couple of things. Firstly, though it seems like things are going well for them, you can't escape the feeling that they are straining every sinew to stay in the game. A couple of wickets and Australia would be bang on top. Remember, Australia have been here before, only to blow West Indies away.

Aaron Finch has got a few problems allotting overs to bowlers here.

Imam rotates the strike with a dab down to third man. Starc ends the over with a bouncer, at Mohammad Hafeez, that seems miles too high but it's not called.

Hafeez looks at square leg with a look of bemusement while the Pakistan faithful start booing in the crowd.

Starc has figures of 0-25 off his five overs now. You've got to feel Pakistan will be delighted with that.

Shot!

Short and wide from Mitchell Starc and Imam-ul-Haq crashes him to the point boundary.

Mohammad Hafeez is ticking along at a run-a-ball 37 so far.

This massive blow off Glenn Maxwell has been a highlight.

One thing Pakistan have done much better than in previous times I've seen them is rotating the strike. It almost gets them in trouble though as a Glenn Maxwell direct hit sees a strangled appeal but Imam-ul-Haq was comfortably home at the striker's end.

The left-hander then ends up in a heap at the other end as he slips looking for a second run.

Five runs - including two wides - come from Nathan Coulter-Nile's fifth over.

Thanks Matt.

These two have shared 54 now and are building a platform that should give Pakistan a chance. But, you feel they are crucial. If one wicket falls a collapse could follow.
