Day two snapshot of third Test

Snapshot of day two of the third cricket Test between Australia and South Africa at Adelaide Oval.

* Score: Australia 6-307 in reply to South Africa's 9(dec)-259

* Man of the moment: Usman Khawaja. The elegant left-hander bats throughout the day to post his fifth Test century, underpinning Australia's innings with a superb unbeaten 138 to become the leading run-scorer in the series

* Key moment: Australia held its collective breath when captain Steve Smith was run out: would it prompt yet another batting collapse? But new chum Peter Handscomb (54) and Khawaja combined for a 99-run partnership to give the host nation a lead

* Stat of the day: 285. The number of balls Khawaja has faced. Perspective: Australia's entire first innings in the second Test lasted just 197 balls and the whole second dig totalled 361 deliveries

* Summary: Australia hold a handy 48-run lead with four wickets remaining, taking the upper hand for the first time in the series. Khawaja will hope the tail wags on day three as an advantage of more than a 100 runs could be match-winning

* Quote of the day: "It was awesome." Test debutant Handscomb.
