Australia today scored 10th highest team total in ODI history. The target is huge but I am surprised to see batting of South Africa, the whole team got out for just 155 runs. You are right, though Australia already lost the series but their today's performance clearly sends a signal that they are not a weak team. Look at batting figures of Australia, only four batsmen scored 431 runs today. Three Australian batsmen were centurion while Alex Carey is the only one to score half century today.
I think when things come to Aussies ego and team dignity then we will have always such kind of new surprises and record to be wrote. No doubt Australian were really off colour and completely out track in recent two match, but now they scored almost same of previous match proteas target combinely in single match and brutally punished thier opponent in order to keep his dominance alive. Honestly I had already predicted their victory as it's huge shame to be White wash back at home for such legendary team. Anyway Aussies rest of lineup were on fire and really dominate things in both field. Hope things will be much more spicy for them in coming series and tournament.
