Quote MessageEngland's ground fielding has been great in the last 10 overs - they have reined Australia in with a series of brilliant pieces of fielding.
Coyte run out (Brunt/Taylor) 7 (Aus 221-8)
Is this another run-out? Coyte guides the ball to Katherine Brunt at long leg and comes back for a second run, Taylor whips the bails off and that's four run-outs! Superb from England, their coaches can take a bow for this excellent fielding display.
Sarah Coyte, with large tattoos covering her left bicep, smashes her first ball from Brunt through point for four, then adds a single to keep the strike.

Quote MessageAustralia have kept the momentum going even when they have lost wickets. That's the exciting things about these teams - they bat right the way down.
Osborne run out (Edwards) 1 (Aus 213-7)
Another direct hit! This time it's the veteran Charlotte Edwards. With only one stump to aim at from backward square leg, she sends Osborne back to the pavilion. Brilliant from the skipper.

Quote MessageI think we've seen more direct hits today than in the whole of the World Cup from the men.

Quote MessageThe run-outs are what have caused the damage for Australia.
Erin Osborne replaces Perry - thankfully we've avoided the world of party politics today as it would have been difficult if we'd had to talk about the effectiveness (or not) of a Cameron-Osborne partnership... Australia have four overs left but their biggest guns have gone.

Quote MessageBrilliant catch, but Perry has played an absolutely blinding innings. Coming in at a tough time with her team three wickets down, she built a partnership and set her team a nice platform to kick on from.
Perry c Sciver b Knight 78 (Aus 207-6)
Perry goes! Knight floats one up, Perry lifts it over mid-wicket and is pouched by Nat Sciver on the boundary. Her 78 came from 96 balls and has been crucial to Australia's chances.

Quote MessageAnya Shrubsole bowled OK. I'd like to have seen more nip from her, but she's been tidy. She will want a little bit more from herself in the rest of the series.
Shrubsole will be the first England bowler to complete her spell here - yielding five runs to the Australia sixth-wicket pair.
Yes, I've got Ashes fever both men/women, also had Open golf fever and still got TDF fever. In fact I've got every known sporting fever going.

With Kate Cross expensive last over, England turn back to vice-captain Heather Knight for some more off-spin from the Old Pavilion End. After a quartet of singles, Healy reverse-sweeps her first four to bring up 200 for the Southern Stars.
In other news, Hong Kong have qualified for the men's World Twenty20 next year after winning a thrilling qualifying game against Afghanistan, who have one more chance to qualify.
Australia wicketkeeper Alyssa Healy - niece of ex-Aussie stumper Ian Healy, and recently engaged to current left-arm terroriser Mitchell Starc - is the new batter. Healy and Perry work Shrubsole for a few singles and a two - seven overs to go.
Cameron run out (Greenway) 23 (Aus 187-5)
Cameron calls Perry for a quick single, Perry has no interest and the ball's straight to England's gun fielder Lydia Greenway at cover point - a rapid throw, Sarah Taylor demolishes the stumps and the retreating Cameron is run out.
Perry digs out a yorker to finish the over - she has 69 from 85 balls, while Cameron has raced to 23 from 21.
England need to put the brakes on here - and turn back to Kate Cross, who can bowl up to four of the last nine overs here. But she drops far too short for Cameron, the ball sits up and is smacked towards the Andy Caddick Pavilion where the players change. Another firm strike over the bowler's head, that's four more and Cross is taking some punishment.
