Here's Poonam Yadav, the leg-spinning wrecking ball crashing through Australia's middle order.

If Gardner is still there at the end, Australia win this game.
Target 133
Gardner keeps the strike as she moves to 27 from 22 balls. Hundred up for Australia, who need 33 from 24 balls.
Gardner goes massive! Australia need a boundary - and the right-hander launches an enormous six into the crowd at long-on!
So, India keep Poonam Yadav's last over up- their sleeves - and turn back to Gayakwad's left-arm spin. Gardner cuts a single to deep extra cover, a lot of pressure on young Annabel Sutherland now - she repeats her getting-off-the-mark shot with another single to long-off.
Target 133
Reddy finishes her four-over spell with a dot, she finishes with 0-33 and Australia need 42 from 30 balls.
I'm so pleased we've got an exciting finish for the first game of the tournament.
Aus 90-6
...but it's good running from Gardner and she's safely back for two.
Gardner pushes a single, they come back for two, the stumps go flying...
Ashleigh Gardner eases the pressure somewhat - Reddy strays down the leg side and quick as a flash, Ash cashes in, helping herself to a four.
Sutherland shows Reddy a straight bat as she's off the mark, drilling a single to long-off.
Target 133
Annabel Sutherland is the new batter - and if her surname sounds familiar, she's being watched from the stand by her father James Sutherland, the former Cricket Australia CEO. And she nearly edges her first ball to the keeper.
They need 51 from 36 balls.

The crowd have come alive. India are on a roll. Australia will have to do very well to win it from here.
Jonassen c Bhatia b P Yadav 2 (Aus 82-6)
And another! Jonassen sweeps and gets a bottom edge to the keeper.
Poonam Yadav, incredibly, has 4-15 from 2.5 overs.

This is where you need to be able to sweep. I'd be looking to get outside the line and sweep everything.
The India fans are dancing in the stands, as well they might - Poonam Yadav, with 3-14 from her first two overs, has the ball on a string. Ashleigh Gardner is playing her late but pokes the ball away for a single, while Jess Jonassen is befuddled by Yadav's googly.
Target 133
Suddenly, Australia are on the back foot, and India are on their toes in the field. Ash Gardner and Jess Jonassen have a rebuilding job on their hands.
Five singles from Reddy's over mean the Aussies need 52 from 42 balls to avoid a shock defeat at the start of their own tournament. At this stage, India were 82-3, this is very close to call.
We're just catching up with the highlights from before that clatter of wickets - with Meg Lanning edging behind, before Alyssa Healy hit a six to bring up her fifty. Enjoy.
Target 133
Well, well, well. That over from Poonam Yadav may have blown this game wide open.
Aus 76-5
Oh, so nearly! The left-handed Jonassen gets an edge, keeper Taniya Bhatia gets a glove to it but can't hold on!
Had she left it, it would have gone straight to Harmanpreet at slip.

This is a massive moment in the game. Again it was the wrong 'un. I'm not sure I've ever seen Perry get a duck before.
Jess Jonassen to face the hat-trick ball. Harmanpreet Kaur brings herself in at slip!
