Johnson puts Australia in command

Two wickets in four deliveries from Mitchell Johnson helped Australia take control of the first Test against South Africa, with the hosts collapsing to 158 for eight at lunch on day three – still 109 runs short of the follow-on.

The paceman struck in the seventh of a nine-over spell when he had JP Duminy (17) and Mark Boucher (0) both caught behind by Brad Haddin, with the hosts’ only resistance coming from AB de Villiers on 63 not out.
