Australia was one of the first teams to implement the player rotation policy. This time they went with a bunch of inexperienced players (Nathan Ellis, Jason Behrendorff, Ben McDermott.etc), and still managed to perform. However in the 3rd ODI things didn't worked as per the plan. Both the opening batsmen (Travis Head and Aaron Finch) were back in pavilion before they managed to score the first run. When Marnus Labuschagne got out, the score was 6/3 after 5 overs. And from there, things went downhill for Australia.
Ok so its because of this player rotation policy not because there players are gone for IPL? I thought Warner, Cummins,
Hazelwood etc are gone for IPL but read in following link that CA has allowed its player to play IPL after conclusion of Pakistan tour. Shaheen Shah got two early wickets and that proves to be trump card for Pakistan.
