Haddin rested for Twenty20 clashes
Wicketkeeper Brad Haddin will be rested from the two Twenty20 internationals against South Africa and will be replaced in the Australian side by West Australian Luke Ronchi.
Haddin's workload in Test series against India, New Zealand and the Proteas has led to the decision to rest him ahead of the five-match one-day series against South Africa beginning on Friday.
"Brad arrived in Melbourne yesterday feeling the effects of his heavy workload over the past three months," Australia's chairman of selectors Andrew Hilditch said in a statement on Saturday.
"In accordance with our policy of managing the workloads of players involved in all three forms of the game, it was decided that he would benefit from not playing in the two Twenty20 internationals.
"Despite being initially selected in the squad, we wanted to assess Brad once he had arrived in Melbourne after playing five tough days of Test cricket in Sydney and, before that, equally as tough matches in Perth and Melbourne.
"It is the same process we employ for all players in that we assess them after they have had a chance to rest and recover immediately following a match, especially if they have been involved in a lot of cricket as Brad has been.
"Given the high intensity of Twenty20 cricket and the upcoming schedule of one-day international matches, it was decided that this was an appropriate time to manage Brad's workload with his and the Australian team's long-term interests in mind.
"It now provides a deserved opportunity for Luke Ronchi to come back into the Australian squad after he impressed in the West Indies last year."
Australia play South Africa in Twenty20 internationals at the MCG on Sunday and the Gabba on Tuesday.
