Some series, in which one opponent completely dominates another, have a signal sequence in which the underlying reason for the gap between the sides is brought into high-definition focus.
In 2010-11, England’s razing of Australia for 98 on Boxing Day brooked no argument as to the space between the teams of Andrew Strauss and Ricky Ponting; in 2013-14, Mitchell Johnson’s destruction of Jonathan Trott on the second morning of the series set the tone for all that followed it.
This time around, there are a few moments that will vie for position. Perhaps it was the first of them all, when Mitchell Starc swung his opening delivery behind the jerky pre-delivery trigger moves of Rory Burns to hit the leg stump. Or maybe it was Scott Boland’s blink-or-you’ll-miss-it destruction of England’s second innings at the MCG.
In Sydney, Pat Cummins’ relentless Australians provided another interlude that illustrated how ready they were for the rigours of a difficult Test series, only to be confronted by an England combination that has never looked close to that sort of level.
On the third morning, after rain delayed the start of Jane McGrath Day and all its pink commemorations, Cummins, Starc, Cameron Green and Boland combined to keep England scoreless for 70 consecutive balls, during which time they claimed three top order wickets.
