England moved another step closer to securing an Ashes double on Tuesday, as the women's side won the first of three Twenty20 matches against Australia.
The 15-run victory has given the hosts an 8-4 lead on points in the first series ever to be played in the new seven-match format.
And with two points available for each of the remaining T20 matches, Australia must win both to retain the urn.
The sixth match of the series takes place at the Ageas Bowl in Southampton on Thursday, and a win for Charlotte Edwards' side will see England celebrate another famous Ashes victory.
Here's a look at some of the key players set to take part in Thursday's vital match.
Sarah Taylor, England
England's hero in their most recent victory, Sarah Taylor, is a woman in form going into Thursday's potentially decisive match.
Taylor was her country's top scorer at Chelmsford, managing 77 off just 58 balls to help post a total of 146-4 which the Aussies couldn't beat.
She was rightfully given the match award and will be looking to put in a similarly impressive display in Hampshire.
Jenny Gunn, England
All-rounder Jenny Gunn also played a key role in England's win in Essex, taking 2-33 to severely limit Australia's potency with the bat.
The 27-year-old removed the visitors' top-scorer, Jess Cameron, for 36 and captain Jodie Fields for just six, denting the visitors' hopes of winning the series.
A danger with the bat in her hand, too, Gunn could have a major say in whether England can wrap things up with a game to spare.
Jess Cameron, Australia
Despite defeat to their fierce rivals, there were some positives for Australia to focus on heading into the second Twenty20 fixture.
Jess Cameron was one of those, top-scoring for the visitors with a respectable 36 and showing positivity in difficult circumstances.
The 24-year-old is capable of even better, though, having managed 81 in the second one-day international last week.
Meg Lanning, Australia
After enduring a miserable performance at Chelmsford, Meg Lanning will be determined to improve on the two runs she scored in Australia's latest defeat.
The 21-year-old has far more move to give, as her 64 in the last ODI of the series at Hove proved.
If the visitors win the toss and choose to bat, Lanning could make life very tough for England's bowlers if she can recapture her best form.
