Khawaja is no stranger to solving problems for Australia. During the one-day World Cup in 2019 he was thrown in at No 5 despite never having batted there in List A cricket. In the current match he was asked to bat there despite never having done so in Tests. By this point of his career the details such as where he bats don’t seem to faze Khawaja. He walked in on the first evening with Australia 117 for three, with trouble looming for the team if he failed, and instead made sure that he didn’t. He first batted through to stumps, then through the first session of the next day with Smith, before assuming the senior role once Smith was gone.
