Australia with a first-innings lead of 145 runs in the sole Ashes Test in Taunton after England's declaration at 9-275 before lunch on day four.
England have declared their first innings at 9-275 before lunch on day four, after avoiding the follow-on in their Ashes Test, leaving Australia with a lead of 145 runs.
With England needing the most unlikeliest of victories to keep the series alive, they will hope for a declaration from Australia on a flat pitch to leave them with a viable run chase.
Starting on Sunday on 6-199, England pushed the score onto beyond the follow-on target of 270 when Laura Marsh hit a back-foot drive to the boundary off Sophie Molineux (4-95).
Nat Sciver fell 12 short of a maiden Test century when she chopped the ball onto her stumps, attempting to run a delivery from Jess Jonassen (2-50) down to third man.
Jonassen also dismissed Marsh (28), leading Heather Knight to call her team in.
After hitting two early boundaries, showing the intent that was conspicuously absent on day three, Anya Shrubsole (11) became Molineux's fourth victim.
Australia declared before lunch on day three after Ellyse Perry's 116 led them to 8-420.
Having won the three one-day internationals, Australia only require a draw to retain the Ashes.
