Spin hasn't done it for Australia so Tim Paine is going back to Kane Richardson, who has 1-19 off his three overs so far.
ENGLAND WIN BY THREE WICKETS
Morgan (69) & Root (50) top-score for England

Australia should encourage Joe Root to play across the line - he might miss one and be lbw or not get his timing right and give a catch.
Stanlake 7-1-32-1
Joe Root and Eoin Morgan continue to do a fantastic job of steadily grinding down Australia.
Just two singles from the over but another six balls of the dangerous Billy Stanlake seen off.

Barney: Doesn’t matter how depleted their stocks are the Aussies always manage to field a highly competitive side. Very rarely do they get pummelled; I begrudgingly respect them for it.
Need 105 runs
Right, that's quite enough of just tapping Glenn Maxwell around for Eoin Morgan as the England skipper belts a conventional sweep shot away for four.

As a captain, you have to understand that England will get 215 if they bat the overs out. You have to take the runs out of the equation and ask yourself "how am I going to get seven wickets?" Get a slip or another catcher in place. You have to bowl England out.
Root 32, Morgan 39
Is this Paine's gamble? The Aussie skipper recalls Billy Stanlake to the attack, in real need of a wicket.
That's not great though - a short, wide one that Eoin Morgan can't quite get enough of, picking up two.
And that's worse. Stanlake strays onto the pads and Morgan clips it firmly away, with Travis Head fumbling it on the boundary.
He just about pulls it back in time to avoid conceding four though.

Tim Paine has to gamble a little bit.

David Wallace: Amelia Kerr has made a day of it in Dublin. Having scored 232 not out, she's just taken 5-17!
Yep, not content with setting a new record for the highest women's ODI score, the 17-year-old Kerr has also helped rip through Ireland to secure a crushing 305-run victory.
I was just happy to bowl a six-ball over and not get a duck at that age.
Target 215
Tidy enough from Maxwell to start as Root and Morgan milk him for four singles to bring the 100 up for England.
Australia are going to add more spin to the mix. Glenn Maxwell is on after drinks...

Nathan Lyon was an English tormentor-in-chief during the Ashes, not only with the ball, but any time he got near a microphone. Today, as 12th man, he's been having a proper chinwag with Tom Curran. New era, handshakes, even Garry has bought into the culture of kindness.
Clever shot. Joe Root drops to one knee to deftly flick the ball high and wide of wicketkeeper Tim Paine, picking up four.
Ashton Agar grimaces - it had been a tight over until then.
That's the cue for drinks.

That boundary brought up the 50 partnership, from 59 balls.
Root 24, Morgan 32
A bit more dross from Andrew Tye, short and right in Eoin Morgan's slot as the England skipper whacks a pull shot through square leg for four.
Nowhere near short enough to test Morgan that.
Sure enough, Eoin Morgan had slid his bat in before the ball broke the stumps. On we go.

Morgan looks as though he was home. It was a nice piece of fielding.
Eoin Morgan scampers a quick single to mid-off, Shaun Marsh picks up cleanly and throws down the stumps.
We're going to have a look upstairs. Morgan looked safe though.

Andrew Tye has a lot of tricks and variations. He's a difficult bowler to face, especially in T20. But when you're in a position where the run rate is so easy, you can just sit in your crease and not look to do too much. He has to do all the work.
