Nathan Lyon struck three times as Australia boosted their chances of victory in the first Ashes Test by reducing England to 85-4 by lunch on day five.
The hosts resumed at Edgbaston on 13-0 chasing an unlikely 398 in the fourth innings, with a more realistic aim being to bat out the day to salvage a draw.
However, their survival hopes were hurt when they lost first-innings centurion Rory Burns for 11, the opener getting into a terrible tangle when trying to deal with a short delivery from Pat Cummins, leading to the ball taking the glove and looping kindly to Lyon at gully.
Captain Joe Root joined Jason Roy (28) and the pair added 41 for the second wicket before the latter perished trying to take the positive approach to Lyon, the ball turning through the gap between bat and pad to hit middle stump after he had given the off-spinner the charge.
Lyon then combined with Cameron Bancroft to dismiss Joe Denly (11) and Root before the interval, both right-handers pouched at short leg following inside edges.
Root had twice used the review system to overturn lbw decisions given by umpire Joel Wilson, though there was no doubt over his dismissal as Bancroft snared a sharp chance straight off the bat to send England's skipper on his way for 28.
Jos Buttler ended the session unbeaten on one with Ben Stokes still yet to get off the mark, the pair facing a monumental task as England aim to avoid falling 1-0 behind in the five-match series.
