Women's Ashes 2013: Natalie Sciver replaces Georgia Elwiss

Natalie Sciver has been called up to England's Ashes squad for the three one-day internationals and three Twenty20 matches against Australia.

The 20-year-old Surrey bowler replaces Georgia Elwiss, who has failed to fully recover from a back problem, in the 14-strong squad.

Sciver was originally only named in the Test side, as England drew the only four-day match at Wormsley.

The first one-day international takes place on Tuesday, 20 August at Lord's.

A new points system has been put in place this summer to determine the overall winner of the Ashes.

Six points were up for grabs for the winners of the Test but as it finished as a draw both teams received two points apiece. Two points are then on offer for the winners of each of the limited-overs matches.

England Women's Ashes Series ODI squad: Charlotte Edwards (Kent) (Captain), Tammy Beaumont (Kent), Arran Brindle (Sussex), Katherine Brunt (Yorkshire), Holly Colvin (Sussex), Lydia Greenway (Kent), Jenny Gunn (Nottinghamshire), Danielle Hazell (Yorkshire), Heather Knight (Berkshire), Laura Marsh (Kent), Anya Shrubsole (Somerset), Natalie Sciver (Surrey), Sarah Taylor (Sussex), Lauren Winfield (Yorkshire).
