South Africa took their time on day 2 and now have a 20 run lead which is handy as this pitch will be difficult to bat on as the test match goes one. If they can get a 100 run lead it will make it hard for Australia. Just like the Australian innings most batsman got starts but couldn't go on to make a century, AB de Villiers has a good chance at 74 not out to make a century and will be a huge benefit for South Africa if he can as that would take a decent lead in the match.
This could be very interesting test as South Africa trying to level series and Australian Batsmen collapse in first inning if de Villiers stay on crease for some time then South Africa will be in safe and good position as he is game changer and need to stay on lets see what will be Australian strategy for tomorrow as they need some early wickets to stay in this test
