Australia looks vulnerable against South Africa. South Africa has a stronger batting lineup when their opening pair fails like today, the other batsmen takes the responsibility. Matthew Breetzke made 88 out of 78. While for Australia, Its either Travis Head, Mitchell Marsh and Josh Inglis. If all three works they get to a good total otherwise they are all out for a small one like today. This makes Australia one of the poor team. I wasn't expecting it to lose to South Africa back to back with such huge margins but they seem struggling every matches. India, New Zealand looks to be in better shape than Australia.
I don't understand the logic in selecting Marnus Labuschagne to the playing XI. When was the last time this guy performed? He is essentially a test player, and it doesn't make any sense in getting him to the limited overs side. Inclusion of such players in turn increases the stress on Mitchell Marsh, who seems to be the only in-form Australian batsman. Travis Head is not in good form ever since the last IPL. It seems he needs another season of the IPL to get back to form.
