Sophie Molineux, the 21-year-old all-rounder, has been added to Australia's Ashes squad for the one-off Test, set to be played in Taunton from July 18.

The Victorian all-rounder, who made her international debut in March 2018, has played 3 ODIs and 15 T20Is, but is uncapped in the longest format. She has picked 21 international wickets but hasn't made a significant contribution with the bat as yet.

She has joined the squad for its first training session at Marlborough College on Tuesday (July 9).

Australia hold a six-point advantage in the ongoing Ashes, having won all the three one-dayers. The Test match carries four points. The points accrued in all three formats will determine the winner of the Ashes.

Australia's squad for one-off Test: Nicole Bolton, Nicola Carey, Ashleigh Gardner, Rachael Haynes, Alyssa Healy, Jess Jonassen, Delissa Kimmince, Meg Lanning, Sophie Molineux, Beth Mooney, Ellyse Perry, Megan Schutt, Elyse Villani, Georgia Wareham, Tayla Vlaeminck.
