It is time for me to pass you back over to the safe hands of Marc Higginson to guide you through the rest of the day.

Australia call for a review, saying the ball touched the ground before Knight could grasp it at first slip. The video replays are inconclusive and the umpires give Blackwell the benefit of the doubt. She survives. England are not happy.

Drama at Canterbury. Heather Knight takes a low catch at first slip that appears to dismiss Alex Blackwell and give Anya Shrubsole another wicket.

But wait just a moment. Australia are not happy. We have a review.

Jonassen on the attack again. She dances down the track and launches her shot away, with the ball bouncing just inside the rope. England need to dismiss the dangerwoman. And do it quickly.

A full delivery from Kate Cross, but a well-timed drive from Alex Blackwell and the ball races away for four. Australia will not need too many more runs before the task will look too steep for England.

Will a batting collapse on Thursday cost England the Ashes?

Well, it won't be all doom and gloom, but a defeat at Canterbury means England would need to win all three T20 matches to retain the Ashes.

"You feel that the pace of the game has changed now that Jonassen has come in. She is the one who could take the game away from England."

Jess Jonassen's 99 in the first innings, before she narrowly fell short of a century on her Test debut, could well prove to be the decisive part of the match.

She does not take long to get off the mark in the second innings, sending one back past the bowler for two off her second ball. She then dispatches Laura Marsh away for four.

A short ball from Laura Marsh and Nicole Bolton latches on to it, pulling a single into the leg side. An otherwise tidy over.

Kent skipper Rob Key has popped his head round, all smiles, as Kate Cross induces a play and miss from Nicole Bolton. She's getting decent pace too, 75mph when she bends her back.  Just a single from the latest set of six.

"We're now at the stage where England would need a record run-chase to beat Australia."

We have fans of all ages who have braved the elements at Canterbury. A couple of youngsters are shown with tiny cricket bats working on their enthusiastic techniques.

Meanwhile, in the serious stuff out in the middle it is another tight over from Kate Cross. Her 18 deliveries so far have only cost one run.

"Trying to chase down anything over 200 tomorrow will be a tough ask for England."

As Alison says, with every run Australia score it just adds to what is already a difficult task for England.

Nicole Bolton scores the first run in three overs as she finds a gap through extra cover, to the right of mid off for a single.

"Charlotte Edwards has to keep her attacking options on. She can't let Australia run away with it by scoring runs. It's about containment too."

"I think Anya Shrubsole could come round the wicket to Blackwell. She's clearly uncomfortable with that line and would ask a different question."

It is a crucial phase in this match, as England do not have many runs to play with after being bowled out for only 168 yesterday.

Anya Shrubsole continues with a probing line and length and claims a maiden. Her 10 overs this innings have seen figures of 1-11. A great effort. But will she be celebrating a victory tomorrow?
