Michael Clarke's fourth Double Century scores this year

Another good innings played by Michael Clarke:

Clarke finished the afternoon unbeaten on 224. That's two innings in this series for two double-hundreds. David Warner struck a highly entertaining 119 earlier in the day, at better than a run a ball. Michael Hussey scored his second consecutive century, an innings that ended only when he played on to Dale Steyn from what became the last ball of the day for 103. If that wasn't enough for South Africa, they also spent most of the day one bowler short after Jacques Kallis left the field in the first session with a hamstring injury.
