Even given the pace at which events unfold on subcontinental pitches, Sunday’s Australian collapse was of epic proportions. Unexpected as well as unedifying, it once again showcased their questionable techniques and addled mindset as they handed over a Test they had appeared in slight control of at the end of the second evening on a platter to India.

Ahead by 62 and with nine second-innings wickets in hand at the start of the third day, Australia swept to their doom in a stunning encore of their shabby second-dig effort in the first Test in Nagpur. The track at the Arun Jaitley Stadium tested the skillsets and the adaptability of batsmen, but was by no means unplayable, which made Australia’s slump from their overnight 61 for one to 113 all out in 91 minutes and 19.1 overs even more inexplicable.
