"Afghanistan have really struggled to get into the game. The opening bowlers were excellent but since then there has been no movement. They've bowled a bit too short."

Smith might be the senior man, in the 90s, but he is allowing Maxwell to be the aggressor here. The 26-year-old claims another four off Dawlat courtesy of an inventive reverse-sweep. The partnership is 51 off 28 balls.

Australia: 316-2 (41 overs)

Batsmen: Smith 92, Maxwell 22

"Australia's is the 17th total of 300 or more in this WC, which equals the most for one WC tournament. There were 17 in 2011 and 16 in 2007. No other WC has seen more than 9."

The 300 is up as Smith drives through extra-cover for four off Nabi. Maxwell then takes over and spanks two consecutive full deliveries for six (one over mid-on, one over square-leg). They are gifts that Afghanistan cannot afford. Maxwell has 29 from 12 balls and Australia are eyeing 400.

Dawlat is back and hoping for a more economical over now that Warner is gone. Maxwell ensures he doesn't get one, though, by smashing a back-foot drive over extra cover for an almighty six. After missing with a clumsy reverse sweep (that leaves him looking like Bambi on ice) Maxwell ends the over with a cut that flies past short third man for another four.

"I think Australia might not be able to get to 400 now that Warner is back in the pavilion. Then again, Maxwell is out there now."

I said Maxwell was capable and he proves it by reverse sweeping his second ball from Nabi for four. It is the highlight of an over that adds eight to the Australian total.

Glenn Maxwell comes out to partner Smith, who carries on where Warner left off with a steered shot down to third man for four. That wicket may well prevent us witnessing a world-record threatening score here now, although Maxwell is more than capable of some big hitting.

"It went miles in the air, but Mohammed Nabi positioned himself very nicely underneath, bringing to an end a brilliant innings. I'm surprised not to see Michael Clarke come in next, considering how little cricket he's played."

Warner's wonderful innings comes to an end, just seven runs short of the highest Australian ODI score of Shane Watson (against Bangladesh in 2011). He looks to smash another ball straight from Shapoor but doesn't connect properly and sends the ball into the stratosphere, allowing Nabi to get underneath it and claim. 178 from 133 balls. Not bad lad, not bad.

Hassan only concedes one run off his first three balls. Then Warner almost takes Smith's head off with a drive down the ground for one. Sweet timing from Smith means the over ends with a boundary, steered past point. This is now Australia's highest ever ODI partnership - 258 and counting.

"Warner is toying with the bowling at the moment, hitting it wherever he wants to. The coaches tell you, 'Do not bowl the length ball when the batsmen are looking for big runs', but that's exactly what Dawlat has done."

Comedian Andy Zaltzman: Warner's the 7th 150+ score in 52 ODIs this year - as many as there were in the first 830 ODIs over 22 years.

Dawlat is heading to some horror figures today. He is heading for a 10+ economy rate after Warner slaps away a full toss through cover point for four before Smith hits the first six of his innings straight down the ground. Warner compounds the bowler's suffering by opening the face to slice a four away to backward point.

There was actually a few decent balls in that over, but you can't expect to serve up a 50/50 ratio of good to bad balls at this level and expect to get away with it, especially when Warner in destruction mode.

A final couple of lines from Napier where Pakistan beat UAE by 129 runs in today's Pool B match.

Here's what both captains had to say in the post-match presentation.

Pakistan captain Misbah-ul-Haq: "That was a much needed win for us. We won by a margin so we can relax now, the next game is really important and we need to focus on that. We have a good net run rate now also."

UAE captain Mohammad Tauqir: "340 was a big total for us, but we batted 50 overs and we are happy with this effort. Anwar is very confident and in great form. We wanted to but on some decent performances, going forward we want to do well."

Hassan has the breeze behind him from the northern end and it serves him well with a wicked inswinger that beats the prod of Smith and flies a few inches past off stump. It is the first time Smith has looked in any way uncomfortable this innings. Just the two runs from the over. It is a rare minor victory for Afghanistan.

"Warner has set a new record for Australia's highest World Cup score. The previous best was 158 by Matthew Hayden against West Indies in North Sound in Antigua in 2007."

"Smith has been the perfect foil for Warner. It's been a very good knock by him in terms of time in the middle."

The young fan who was hit in the stands has now got a bandage (presumably packed with something cold) wrapped round his shoulder. He looks a bit glum but otherwise OK. There aren't many unhappy faces amongst the Australian crowd around him, though. A trio of singles is followed by consecutive boundaries (a straight four and a whipped six) off Shapoor, who looks to the sky in frustration. It is becoming a very familiar sight in Perth.

Warner now has his highest ODI score, beating his previous best of 163 against Sri Lanka in 2012. These two have now put on 232 together, with Smith only scoring 66.
