It is six years since England batted out the final day of a test match to scramble a draw but that is the challenge they faced overnight, otherwise Australia will retain the Ashes. Somehow they will have to muster the defiance to repel a rampant Australian attack without their captain Joe Root, who was bowled first ball by Pat Cummins as England were cut down by the new ball in the final seven overs before the close.
Cummins was on a hat-trick after he dismissed Rory Burns, caught off a leading edge, and bowled Root to leave England nought for two.
England limped to 18 for two thanks to Jason Roy showing some mettle in defence, but Australia are just eight wickets away from taking a 2-1 series lead and look unstoppable in their quest to win their first Ashes series in England since 2001.
If that happens, Root will face serious questions about his future. There was a time when it was normal service for an England captain to lose Ashes series home and away and survive. But these days England are accustomed to beating Australia on their home turf and Root has always dreamt of emulating Michael Vaughan's 2005 victory. It is not going to happen now and, even worse, Root's form has deserted him. This was his third duck in five innings, two of them first-ballers, and to rub it in even more, Steve Smith continued his dominance with an innings of 82.
When Burns was dismissed, Root could have opted for the protection of a nightwatchman. There are times to seize the initiative and times to back away. But Root took on the responsibility, walked out to bat and a couple of minutes later was walking back shaking his head. The crowd were stunned, Australia jubilant.
