Matthew Renshaw's innings of 190 helped Australia recover from a challenging position against South Africa in the first Test. Australia, who were 124 for six, reached a total of 390 all out.
Renshaw, batting at number five, was the last man out just after tea, having batted through two extended sessions. His performance, described as patient and concentrated, was his Test-best and likely career-defining.
South Africa concluded day two at 27 for one before bad light led to an early close. The Durban pitch is anticipated to turn more as the match progresses.
